Thanks! By far the best video tour of the inside of the Appartamento I have seen. I've had my Appartamento for about 3 years now and love it. I have had to replace the vacuum relief valve. Have a new issue that just popped up. The machine seems to be overheating and have water coming out of that little "button" under the group head. The safety valve is being tripped due to overheating. I contacted Rocket so we'll see what they say, hopefully it's an easy fix!

[@Wholelattelovepage]

Hey austin, Thank you a whole latte for the comment! Hopefully Rocket can help you out. Overheating sounds like pressurestat or relay.

[@IbHustln]

@@Wholelattelovepage Have a new Pstat on the way from Rocket. Do you guys at WLL happen to know how easily a new one can be installed? Obviously there are the two wire connections on top, but does the bottom silver metal base of the Pstat need to be unscrewed from the tube below as well? Or can the plastic part be pulled out and just slip a new one into the silver metal base? Thanks!

[@IbHustln]

UPDATE - For anyone having the same issue with their Appartamento. Ordered a new P-stat from Rocket USA. It does not look like the one in this video and is the same as the original P-stat in my machine (Round in shape, brand name MA-TER). Unfortunately a new P-stat did not fix the over-pressure issue in my Appartamento. Just FYI for anyone replacing the P-stat at home themselves you have to take the entire casing off of the machine. The P-stat sits on top of a rounded pipe below and a bolt threads into it below securing it to the pipe. So basically you have to turn the bolt below the P-stat counter to get it off.

[@nolanreed7090]

@@IbHustln Have you been able to fix the issue? My machine is starting to over-pressure and releasing steam above the drip tray on a fairly regular basis. I'm hoping I can fix it at home and not have to box it up and ship it across the country for a warranty repair.

[@MikeFLHT]

This is a great video, thanks WLL. It's really great to get the visuals of what's happening inside the machine and to see what does what. This is the first time I have heard there is a water level marked on the water tank of the Appartamento. I checked my owner's manual, and it didn't mention it there. I've been filling it as close to the top as I can for more than a year now.

Hey MA, You are welcome. Stay tuned - more Appartamento videos to come including housing removal/install. While you can adjust the P stat to increase boiler pressure/temperature keep in mind that increases your brew temperature as well. Can deal with that by using a longer cooling flush before an extraction.

[@genericgymvlogsph9739]

Awesome detailed walk-through! I run my Appartamento in a little cafe in the Philippines and it keeps up all day long! The only downside is that it cannot be plumbed! I have been thinking of a way I can setup a 5 Gal Jug underneath the counter and pump water in the machine whenever the machines empty water sensor goes off. Some sort of relay that goes into a timer that will pump water into the reservoir for 'X' amount of secs till the reservoir is full, then it stops. So I don't have to refill it every 15 mins. 🙂

[@jdpst20]

I've had my Appartamento since 2017 which I got from you guys and It's been running like a champ since! Only one small repair under warranty which got the part out to me super quick and with Customer Support was able to diagnose the issue and get me back to brewing in a few days. Other than that, I keep the machine clean and she runs like a champ and my wife and I use it pretty much every day sometimes twice a day since we bought it. I too have recently saw some videos about the brew pressure and brew water temp and am going to try this for myself as mentioned below. I've had no issues with whatever my machine BAR is set to however after diving deeper into the topic I could say that the machine pumps water maybe slightly on the high end and am wondering if lowering the pressure to 9-10 will yield in a better extraction by allowing the coffee more time for full extraction potential. I typically run the same coffee day in and day out with the occasional fancy brew. I have a triple basket and am usually always running 20g and while shooting for 40g yield am usually way short of that 25-30 second from 1st drip. If I go to 30 seconds I'm usually at 60g. The 60g usually does task good and produces good crema I'm just wondering if I can make the flavor or extraction better by adjusting anything or if I'm almost spot on. The coffee is in no way "watery" but initial extraction does come out I would say on the faster side and that slow drip you see with naked basket is just not there. I ordered a temp gauge too for the Group Head to really dial in brew temp after playing with the pressure I'll see what happens. I also grind on a Silencio and am usually at 1.5 grind setting almost the lowest it will go. Lastly I've ordered an IMS screen to see if that improves water distribution on the puck. All in all I still LOVE this machine.

[@jdpst20]

well... I dialed the Silencio Grinder to basically 1 with 0 being bur on bur and I've yielded a nice shot of 20g in 42g out in about 28 seconds. The flow rate is MUCH slower out of the extraction and the flavor of the shot is totally different. Ended up with about 45ml of espresso with a nice layer of Crema. I did a 5 second pre infusion too. I'm anxious to see what difference if any it will make when I can monitor the brew pressure and see if adjusting it to say 9-10 Bar if it's currently set to 12-13 will make a difference. Then I once BAR is set I'll install the temp gauge and see about the difference it makes once the brew temp is fully up to temp and I'm not just guess. Finally I'm really interested in possibly trying the Flow Control Valve for the Rocket Appartamentto and messing around with those settings.

[@Wholelattelovepage]

Hi Joshua, Thanks for the long-term owner report! Glad our CS staff got you squared away quickly. As a pressurestat controlled machine for temperature cooling flushes are the way to work the temp - guessing you knew that. I would not worry too much about extraction timing so long as flavor is good. As for brew pressure, manufacturers like Rocket, Bezzera and others set the OPV to a slightly higher pressure on their vibration pump machines as compared to their rotary pump commercial machines. Typical rotary pump puts out 10-11g/s while the vibration pump in your machine and others does 7-8g/s. It's unlikely you're hitting the OPV set pressure when brewing as some pressure is dumped through the coffee and the OPV is much further back in the brew water hydraulics. While pressure and flow are not the same they are related. Manufacturers set higher OPV on vibration pump machines to keep the flow rate closer to rotary pump machines.

[@jdpst20]

@@Wholelattelovepage Thanks for the reply... Yes usually I will wait about 20-25 min before using machine for it to heat up... do a 5 second flush before pulling shot. IF the machine sits on for a longer period of time Ill flush until I don't see water with steam about 10-15 seconds. Usually if I'm making milk drinks I'll grind a bit Corser and have a 1:3 or even 1:4 ratio get good crema still and the flavor is still good to me mixed with milk... I was messing with a 1:2 ratio this morning with a much FINER grind and I could def tell a difference in flavor. If it wasn't ground fine enough and I had say a 1:2 ratio 20g to 40g in 50ish ML in say 10 seconds the coffee was bitter and sort of one dimensional. Grinding finer to get a longer extraction really changed the taste I think. Instead of just adjusting brew pressure at the OPV would you suggest investing in a Flow Control Valve to experiment with restricting flow? I did see your videos on brew pressure and how it can effect taste ect.

[@tommer5008]

Unfortunately, i purchased mine there in 2018 and only 8 months out of warranty it now goes overpressure in the boiler. I now live near the Cape in Mass and no one repairs over here.

Interesting! Mine looks a little bit different though. I still have an older model. The pressostat looks different and has a a slotted head-screw on it and also it doesn’t yet have the eco mode. It’s great to see and to understand better how the machine works, but to be honest the only things I would do as an mechanically unskilled user is to change the brew pressure via the opv valve if I had a grouphead manometer, adjust the boiler pressure via the pressostat if I had a grouphead thermometer or, and that‘s the only thing I have done so far as I don‘t own the appliances above yet, descale the water sensor when the machine won’t fill even though there‘s water in the tank.

[@back_to_the_bike8820]

The factory settings are amazing. It should not be up to the buyer to open the machine, but he should know that there is a real qualitative gain in cup by lowering the extraction pressure to 9 bars, and by lowering the boiler pressure to 1, or even 1.1 bars (almost no impact on the steam pressure which is powerful on this machine, except if you have to make more than 4 or 5 milk drinks). Of course, for the boiler, it could be argued that this may depend, among other things, on the origin of the coffee or its roasting. But we are on a group E61 which is not intended, it seems to me, for light roasting. Moreover, many consumers say they are sensitive to temperature and forget to have hot cups (many baristas also neglect this variable). It would be interesting to have a customization of the machine so that these two adjustments are accessible without disassembling (that must be imaginable for the pressure of the boiler, on the other hand for the access to the OPV it would be less, obvious).

[@Wholelattelovepage]

Hi bttb, Thanks for adding your thoughts. As an HX boiler machine with temps controlled by pressurestat variations in brew temperature are typically done using cooling flushes prior to making an extraction. Fairly typical among machines at this level the brew pressure and boiler pressure adjustments are under the hood. Marc

[@back_to_the_bike8820]

@@Wholelattelovepage Thanks Marc. I'm sure you've already tried (especially on the Rocket Appartamento) to touch the OPV to lower the extraction pressure to 9 bars and to lower the boiler to 1 bar. The coffee is then so much better.

I've never used that model but it should work on any single boiler machine were you can divert some water from the brew group to the steam wand while brewing. AJ

The video was excellent. I appreciate it. I recently purchased a new Rocket Giotto Cronometro R machine, and I've had it for around 1.5 years. I've noticed a significant amount of rust and deterioration in the front area of the bottom plate, where all the machine parts rest. What could be causing this rust, and what steps can I take to prevent it?

[@Wholelattelovepage]

Hi n, Rust happens when frame paint coat gets scratched and moisture makes contact with bare metal. To prevent be careful when removing drip tray to avoid damaging paint and keep the area dry.

[@johnmorrison7171]

Thanks for this, can I adjust steam pressure with this style of pressurestat? the older ones had a screw, this one is waxed in place. I have already adjusted brew pressure down to 9 bar but the steam is to high and (for me) makes steaming milk very difficult.

[@Wholelattelovepage]

Hi JM, Thanks for the question. It likely is adjustable if it's the box type stat with wax mark. But, understand the manufacturer put the mark there for a reason. Likely to hold the position set and/or to alert for tampering. Don't advise changing the setting - lowering pressure in the boiler will lower the brew temperature as well. As an alternative you could bleed some steam through the wand before frothing to reduce pressure or take water out through the hot water wand until the pump kicks on and adds cool water to the boiler which will lower the pressure. Hope that helps!

[@adventurebranding]

Superb video, if my pressure is dying every now and then, like in the morning after heat up, would it be that the pressure valve is faulty at the bottom that sets the bar?

[@Wholelattelovepage]

Hi Alex, Pressure drop can be caused by a pressure leak or by the boiler not heating. Most likely place for a pressure leak is from the vacuum relief valve on top of the boiler. Once closed when the boiler reaches boiling temp it's unusual for the valve to leak. If it leaks it would make a sound. Leaks of pressure from anywhere would generally have a sound of some kind. Pressure dropping after initial heat up could indicate a bad component like a pressurestat or relay that fails when it gets warm.

[@kelvinlee4295]

Are you able to adjust this Campini pressure stat? The screws are covered in red plastic, making them very difficult to access. I want to lower my boiler pressure.

[@Wholelattelovepage]

Hi KL, The pressure stat is adjustable. They put the red stuff on the adjustment to discourage end users from adjusting. Know that if you lower the boiler pressure you will also reduce the brew water temperature - lowering the pressure reduces the temperature in the boiler.

[@lepepus]

Great video again. Feel like I know my machine better now, thanks! I have a question about the OPV and the fact that the Appartamento is known to be set at a pretty high pressure. Mine reads 11 bars on my grouphead aftermarket gauge with the blind basket. There is alot of discussion if we should turn it down to 9 or not. Been tempted to do it but reading a lot of conflicting posts. Any thoughts on that? Any issues in doing that?

[@Wholelattelovepage]

Hi Phil, Thanks for the comment. I do have thoughts and they're based on conversations with machine manufacturers. I'll get to those in a second... First, I think a lot of people get wrapped up in 9 bar as a magic must have number for espresso extractions. I've had plenty of incredibly good shots pulled at higher pressure like manual lever shots and lower pressure like flow profiled extractions. In my experience I find flow rate of brew water is far more impactful than +/- a couple bars of pressure. So what do the manufacturers say? Luca Bezzera says they set their domestic machines with vibration pumps to 11 bar in order to provide a good potential flow rate of the brew water. Vibration pumps have lower flow rates of 7-8 g/s than the 10-11g/s from commercial rotary pumps. There's no issue with setting to 9 bar. I say give it a try, taste and see if it makes any difference in the cup. You can always put it back to 11. You'll likely be grinding a bit coarser and maybe that works out with your other variables and maybe it doesn't.

[@lepepus]

@@Wholelattelovepage thank you for the comprehensive reply, will give it a try!

[@timgerber5563]

Hey Phil, just one thought I had regarding the exact same thing: Since the pressure gauge at profitec flow profile equipped machines also reads the pressure without a blind basket, but rather with ground coffee in the basket, I would rather go a bit higher than 9 bars with pump pressure, because essentially pressure is lowered by there being a release in terms of water flow through the espresso puck. So I would probably dial in my espresso first, then reduce pressure to see what the pressure gauge reads while extracting espresso. As wholelattelove pointed out extraction times might go up with less pressure, maybe requiring you to grind coarser, but I believe this way you get a better idea of what the actual brew pressure is instead of just the nominal pump pressure.

[@lepepus]

@@timgerber5563 that is correct, but based on some, pump pressure should be 9 which, you are right, will end up closer to 8 in the basket while brewing and that would be the "classic" way to brew. Because dialing in pressure at the puck level would be very irregular as all coffees are so different and flow differently. Pump pressure at 9 appears to be the sweet spot between good pressure for extraction and preventing channeling... Anyway, James H. appeared really ticked off at the fact the this and so many other machines are set higher than 9. :)

[@deantchi]

awesome video Brian! do you know why my apartmento would heat up properly up to 1.1 bar, then after about 45mins, the pressure would just drop to about .75 bar and stay there? it would then rise again if I pulled steam, hot water, or brew?

[@Wholelattelovepage]

Hey dc, Thanks for the comment and question. Not 100% certain but sounds like the pressurestat is not operating properly.

[@Architect_Art_Vandelay]

Rocket's manual seems to suggest against descaling. I've had the machine for a while and the water I use (although bottled) is still fairly hard. Should I descale my machine?

[@Wholelattelovepage]

Hi DA, Most all manufacturers recommend against end users descaling espresso machines. Why? If severely scaled, scale particles can break loose during descaling and clog internal components of machines. In reality, descaling HX boiler machines like yours is relatively low risk. Should something clog during descaling it's fairly easy to access and correct - if you're comfortable using basic tools. And, unless scale deposits are moderate to severe you're unlikely to have any problems. I'll link a video below showing how to descale an HX boiler machines like yours. Going forward, it's best to filter your water using calcium to magensium ion-exchange to reduce calcium hardness while maintaining a mineral level needed for good flavor and corrosion prevention. BWT Water and More has a number of solutions including low cost drop in reservoir pouches: www.wholelattelove.com/products/bwt-bestsave-s-anti-scale-filter and a filtering pitcher: www.wholelattelove.com/products/bwt-penguin-2-7-l-water-pitcher Both of those when used as directed prevent scale from happening in the first place.

[@Lorenzo1972.]

Is there any way to adjust the water temperature of the Appartamento? My sense is that it’s running too hot.

[@Wholelattelovepage]

Hi L, Yes there is a way. Here's a link to place in this video which show the pressurestat: kzbin.info/www/bejne/j4THm59miqqUerc In more recent Appartamentos the pressurestat will look like the one in the video. May look a little different in older models. Adjusting the pressurestat by turning the control changes the pressure (and therefore the temperature) in the boiler. Notice in the video there's red paint over the adjustment. Rocket would prefer the end user does not adjust the pressure/temperature. Know that in heat-exchange boiler machines like the Appartamento the boiler typically runs much hotter than the desired brew temperature. The difference between boiler temp and brew temp changes depending on variables like how long the machine has been on, time since last use and ambient temperature. Standard operating procedure for HX boiler machines controlled by pressurestat is to use a cooling flush prior to making espresso. To do that, right before pulling a shot, without the PF attached lift the lever and let the pump run until brew water flow from the group has smoothed out with no excessive steam or bubbling. Usually takes a 3-8 seconds for smooth flow. Using cooling flushes like this allows a user to quickly manipulate brew temps. For cooler temps flush a bit longer. For hotter temps use a shorter flush. Here's a video on how to use cooling flushes: kzbin.info/www/bejne/mHm2d3WDaMiKfqs Hope that helps! Marc

[@Wholelattelovepage]

Hi Tony, continuous release of steam from the vent means the boiler is too hot or the valve is defective and stuck open. Boiler could be too hot because pressurestat is adjusted to high or heating element is not turning off. If boiler is too hot the high limit switches on top of boiler would probably trip.

[@tonyrodriguez9942]

@@Wholelattelovepage Thanks for the insight, I'll give it a try. However, my limit switches have not tripped and pressure remains 1.0 to 1.5 bar the entire time once the machine is brought up to temp. Must be a defective safety relief valve.

@@Wholelattelovepage I've seen a number of boilers and elements in similar machines that have a V-shaped o-ring groove along the sealing surface. Presumably this is for a Viton (or other FKM) o-ring. Is there a reason these never seem to be used? If just using a teflon gasket, why even have the V groove?

Did I see a manual boiler drain valve at the bottom of the copper service boiler to allow draining of the boiler?

[@Wholelattelovepage]

I believe what you saw was the boiler's mounting bolt. Fairly easy to drain. If you don't know how here's a video demonstrating draining of an HX boiler Profitec Pro 500. Procedure essentially the same for the Appartamento: kzbin.info/www/bejne/p6vWcppvpp52j68

Hi Whole Latte Love, if I wanted to connect a brew pressure gauge to my appartamento which line would I tap into with the manometer capillary tube? thanks

[@Wholelattelovepage]

Hi o, Brew pressure gauges usually read pressure in the line after the pump and OPV. You need to put it in the line running between the OPV and the heat exchanger. Since the Appartamento has an E61 group an easier option is mounting a pressure gauge to the port on the group. There are aftermarket gauges available which mount in the hole revealed after removing the Allen head bolt in the sloping front of the group. Gauge at this location gives a better reading of actual pressure in the group during an extraction.

@@Wholelattelovepage thanks, your help is much appreciated

My machine will not stop heating until the point where the safety valve releases steam from the front center bottom round port. and the pressure gauge is way too high . Is there a quick fix ? I can guess that some thermostat sensor is not working. it should shut off the heating once it has reached the correct temp and pressure.

[@Wholelattelovepage]

Hi h, Can't be certain from here but sounds like a malfunctioning pressurestat. The pressurestat controls boiler heating. When it reads the proper pressure it sends a signal to the controls to stop heating the boiler. They can malfunction and/or not read pressure in the boiler properly due to obstructions like limescale deposits.

Hi Marc from WLL and team, My rocket apartamentos power switch is stuck and won’t go up to the “on” position. Did the switch fail ? If so, is there a video you may have on how to replace that ?

[@Wholelattelovepage]

Hi B, We do not have a video showing how to replace the switch. But it's fairly easy to do once the machine's housing is off and we do have a video for that: kzbin.info/www/bejne/mIO3g3uKesufrrs Marc

[@chulolo997]

I tried pulling out the water level probe to see if it was causing the overheating issue but now the probe won’t get tightened when put inside the boiler, do you know what would be the issue?

[@Wholelattelovepage]

Hi c, The probe goes thru a teflon fitting. The nut there can be tightened. It's a compression fitting that clamps the teflon fitting around the probe.

[@chulolo997]

@@Wholelattelovepage it seems that the teflon fitting has fallen inside the boiler, any suggestions on how to take it out? Or if I can just leave it inside

[@chipburns3900]

Excellent video! My Appartamento has been consistently overheating on startup for a bit. I've swapped out the pstat and that hasn't corrected it. Any tips on what to look for next?

[@Wholelattelovepage]

Hey Chip, So after startup it's not overheating? Or does it always stay too hot? Just want to make sure you're not taking the hissing as the boiler reaches 212F/100C as overheating. Hissing or steam for 30 seconds or so is normal as the machine is heating up prior to the vacuum relief valve closing on the boiler. If you have continuous hissing or steam perhaps your vacuum relief is clogged so not closing all the way and needs cleaning or replacement.

where can i order the light switch?

Nice! Can you do this with the BZ10? Thanks

We're planning to to this for a bunch of machines! Hopefully we'll make it to the BZ10 eventually.

Is it safe to descale this machine?? I think i have scal buildup inside the boiler.. any suggestions on what i can do? I don't have professional service available where i live so any advise will be appreciated

[@Wholelattelovepage]

Hi TCA, Heat-exchange boiler machines can be descaled. If you know there's severe scale buildup in the machine be aware descaling may not get everything and there's a risk some scale could break free without dissolving and plug components in other parts of the machines. If scale is mild you can follow this video on how to descale a heat-exchange boiler machine: kzbin.info/www/bejne/r3aql6yAoLyGp7c

[@Coffeesatisfaction_]

@@Wholelattelovepage Does this apply to Rocket appartamento?? As it has a Copper boiler & rocket does not recommend descaling their machines.. any updates on this topic?

[@Wholelattelovepage]

@@Coffeesatisfaction_ Most every manufacturer has some language in their manual about not descaling their machines or having a professional technician perform the service. I believe it's there to cover themselves from end users neglecting the machine, having lots of scale build up then descaling the machine and having issues due to clogs caused by large pieces of scale plugging machine elsewhere. If a machine is not neglected and scale is very minor then descaling a machine with a heat exchange or single boiler is okay for a home user. Marc

[@Coffeesatisfaction_]

@@Wholelattelovepage makes sense.. but how do I know for sure if the boiler has scale inside?

[@Wholelattelovepage]

@@Coffeesatisfaction_ One easy way to get an idea is to remove the mushroom from the E61group head and check for scale there. If there's a lot, that's a good indication there's likely scale elsewhere. Here's a video with more on the E61 group and mushroom: kzbin.info/www/bejne/e32sqHdqZdmmqNU

So......can the "Eco mode" be turned off then? ie. it doesn't go to sleep after 90 odd minutes?

[@Wholelattelovepage]

Yes, that green switch on the underside enables or disables the eco mode function.

@@Wholelattelovepage Aww......brilliant! Cheers from Ireland :)

[@mustafading]

No......2019 European version doesn't have that button/switch option. Bummer. :)
