Hi John, This was one of my very first videos. You're absolutely right about it being an advert for my company. It shows very little of what is actually done on a service. In hindsight I could've titled it differently. Thanks for watching and I appreciate the feedback, enjoy the rest of your weekend!

@ lol 😂 I wasn’t being nasty I just was hoping to find out what an gas engineer did on the first service as mine is due soon, and unfortunately like a lot of trades nowadays there are a small number that do just as much as they need too. Fortunately I have found a local gas engineer lined up for mine. Have a good day

@JohnMyer999 no worries I'm hoping to do a video soon which shows what a full strip down service entails. The Baxi 800 boilers are extremely easy to service correctly. Enjoy the rest of your weekend!

Thanks for the comment! Have a great weekend

The easiest places to reduce pressure is by a drain off valve or bleeding a radiator into a jug

Only the 600 and 800 boiler range as far as I know

Thanks for the comment! I'm glad it helped you out

I can agree with that. Thanks for the comment!

No worries, glad it helped you out!

@@RobertSmith-vw9lg If a customer leaves the filling loop open and the pressure relief valve goes off....then yes, it could flood a house. Unlikely to happen but it can 👍

Oh, the filling loop was passing on this one, so it was continually dripping and filling a bucket. That's what my original call out was for

Okay fair play 👍

Hi, This is what a quick google of F5 error code means: The F5 error code on a Glow-worm boiler indicates that the boiler is overheating. This fault prevents the boiler from working to prevent damage to itself. Causes low water flow, faulty thermistor, blocked heat exchanger, limescale build-up, and airway blockages. Risks damage to the boiler's internal components and risk of fires. Safety It's unsafe to operate the boiler with this fault You should use a Gas Safe registered engineer to diagnose and fix the fault How to fix A Gas Safe registered engineer can diagnose and fix the fault Regular professional maintenance can help prevent the fault I would say you’ve got some sort of blockage or flow issue causing the f5 fault …. But without seeing it myself I can’t say for sure

Thanks for the comment. I'm glad it helped you out! Have a great weekend

It's real; it's in the UK. We have low volume dual function systems like that, which heat water like a boiler and circulate it it for heating. I've been gone from the UK for over forty years now, but when I bought my first house there, back in '81, it had a system like that. It was in my kitchen on the wall next to the kitchen sink. If I remember correctly, it used 1/4" piping (yeah, right!?) for hot water circulation. We called that "microbore", IIRC, obviously needing a pump for circulation. Our houses are smaller, and there's less room for copper piping, and certainly none for forced air circulation. A small volume of water forced around the house, driving high efficiency radiators...

In the UK this is referred to as a boiler.

@@dpjplumbing Cool in America its called a Tankless Water Heater. 😂

@@Alan-n6u8bAmericans having to spell out exactly what something is as per usual. This is almost as good as ‘horseback riding’

Guys this is nonsense 😂

Yep! Can't believe what some people get away with, it's unreal

No worries!

Thanks for the feedback, I think I didn't press any buttons so the display light didn't come on....making it more difficult to see. I will see if I can do another one with the display light on for easier viewing. Thanks, Dan

The F4 fault code on a Glow-worm boiler indicates an ignition problem. This means the boiler is having trouble igniting, which can prevent it from providing hot water and central heating. Causes Faulty ignition electrode: The electrode may be worn out and need replacing Blocked burner: A blockage can prevent the boiler from igniting properly Faulty gas valve: A stuck gas valve can prevent gas from reaching the burner Low gas pressure: The boiler may not be getting enough gas Dirty spark generator: The spark generator may need cleaning or professional attention Wiring or connection problems: Loose or damaged connections can disrupt the electrical signals that tell the boiler if a flame is present Solution To fix an F4 fault, you should call a Gas Safe registered engineer. They can assess and rectify the issue, which may involve cleaning or replacing parts, checking the gas flow, or troubleshooting electrical issues. Safety The F4 fault code locks out the boiler to prevent unsafe operation, such as gas leaks or overheating. You should never try to fix a gas appliance yourself. Sorry I can't be much more help

No worries, I'm glad you're sorted!

If it’s dripping from the center of the lever/valve its likely it’ll need replacing. The only advice I can offer is to open and close it several times to see if that helps re-seal the insides BUT this could also make the drip worse. You can always leave it for a bit to see if it self seals. Otherwise, it’ll most likely need replacing

No worries!

Thanks for the comment, glad it helped you out!

This should be repaired by a qualified gas safe engineer. As you should have the appropriate testing equipment and knowledge to carry out the tests. I'm not sure if you are, as I can't tell from your profile/username.

I put it down to the location of the seal being below the test point and with the case on the boiler, the fan was sucking the products of combustion away from the test point. But with the case off the boiler, the fan was sucking air from the room, instead of outside....this meant the products of combustion lingered around the seal.

Ty. I get an intermittent gassy smell from top of combi where the elbow flue is screwed to boiler. 3 gas safe boiler services all check out fine and pass. Could this seal be the issue and can be missed on service?

@watchman7471 I would doubt it would be the issue. As this is inside the boiler and the boiler is technically room sealed. But without testing it myself, I can't rule out any possibilities. All I can do is advise getting a qualified gas engineer in to check it out....but it sounds like you've already done this

@dpjplumbing ty. Had 3 engineers do a service. All passed each time they couldn't find an issue. I'll get the elbow removed to see where it joins boiler as smell coming from there. Appreciate your replies 🙏

Sometimes the boiler will not pick up any errors or issues during normal operation so you won't know there is a problem. But inside the boiler it could end up recycling Products of Combustion which can cause condensation to build up inside the boiler and corrode parts. It can also cause the burner to burn incorrectly, which can cause the boiler to cut out or produce dangerous amounts of Carbon Monoxide. The boiler should cut out if it starts burning incorrectly and eventually go to a fault code, that's if it is particularly bad. If it's just a slight weep then usually a build up of residue where it is weeping

No worries! Glad I could help you out 😁

It could be that the mains water pressure isn't powerful enough to raise the pressure that high Or a common issue with this boilers is the digital pressure sensor gets clogged with debris/sludge and it stops reading the correct pressure. Without testing it myself, I can't tell you if any of these are the actual issue. But the recommended pressure from boiler manufacturers is for the pressure to be between 1bar and 1.5bar. Hope that helps.

Thanks for taking the time to leave a comment. I've found that the simple videos like this are incredibly helpful when the instructions are just not clear. Thanks for the feedback, enjoy your weekend!

Thanks for the feedback, I will look into it

No worries, thanks for taking the time to leave a comment, it's much appreciated 👍

Expansion vessel had no pressure so the expanded heating water had nowhere to go, so the pressure goes high and causes the Pressure Relief Valve to dump excess pressure....which causes the pressure to drop when the heating water cools down and contracts

Hi, I've never come across this error code before. Is it on the EPH thermostat display or the actual boiler itself?

Glad it helped you out. Seems to be a very common issue that one of the valves goes a bit stiff.

You are very welcome

Should do

I’ve turned both valves and it’s not worked. Also tried taking off the black caps to make sure the valves are turning, which they are. Any idea what the problem might be? Appreciate any advice 🙏🏻. Thanks in advance

Yes, the valves on this particular filling loop seem to go stiff over time. I'm glad it helped you out, thanks for leaving a comment/feedback. Happy new year!

How frequent is it? After the heating system has been on? If it's after the heating system has been used then it's likely the expansion vessel needs repressurising. If it's dropping pressure without being used...then there is a leak somewhere on the heating system or boiler.

Turrent seal and flue seals all needed changing on this one

@ nice to know I’m half way through my gas course, already a plumber

@lukestone5121 good luck with it all. Plenty of useful information out there to help you out. You never stop learning

No worries! Have a happy new year!
