[@MikeZamonski]

I called Mike about a problem with hot water turning cold, he told me to check the water flow servo valve. Watched his video on it and it did the trick. Thanks Mike.

[@asusfood6418]

Mate this is a fantastic video. I pulled my flow sensor apart, cleaned it, reinstalled, and am now back with hot water.

[@johnscurlock9402]

This video saved me ~1000$ today. I was able to remove both the inlet side of the fitting and the water flow sensor side of the fitting without disconnecting any wires, I was able to clean the flow turbine and reinstall the whole thing. Everything worked flawlessly afterwards. The hardest part was removing the wire spring clip that holds the turbine in the flow sensor body. In any case, thanks so much your video and explanation is truly appreciated.

[@douglasmcgill282]

I will be attempting this tomorrow. Extremely helpful information! Thank you for this level of detail. Great video!

[@lawrencewhite2803]

Hi MIke, I have an R75ls that stopped working. No error code. I watched this video and one of the others, and it seemed that there may be an issue with the flow turbine. The videos gave me the confidence to proceed with the repair. When I opened the unit, I traced the wires you identified to their respective connectors. I found that one of the 3-wire connectors was green and corroded. When I took the connector apart, there were only two pins visible instead of 3. Since the wires came from the flow turbinie, I assumed that the signal was not getting to the contol board. I cleaned the connector and soldered jumper wire to the wires that were missing the connector pin. That solvled the problem! Thanks for your videos. You are a great instructor! Larry.

[@jcooke2789]

You sir...I could just hug you! After a $200 service call and an $1100 quote just to change out the flow sensor I stumbled on this video...I replaced the flow sensor myself with no success (its probably still a good part)....but the paperclip in the flow turbine did the trick!!! I have an RUC98i unit that I was about to let get replaced and tried the paperclip suggestion and IT WORKED! I have been without hot water in the house for almost 2 weeks, so glad I can get back to normal! Thank you for all your videos!!!!

[@galvinpdx]

Thank you so much! I had flushed my water heater, but accidentally was pumping into the hot outlet. That caused a piece of debris to get lodged in the impeller. Easy fix after watching this video!

Mike - I have a State Water heater made in 2008 (which isn't even a State I'm told as it's made in Japan). That being said I just want to thank you for the video. I would have been taking cold showers for two weeks tomorrow. I watched your video and when I saw the sensor I realized I had an identical one in my unit. I pulled it apart Monday night and cleaned the valve with some PB Blaster and blew compressed air through it (as was recommended in another video I watched). Reassembled and got nothing. I'm in the automotive industry and quickly realized the flow sensor is basically a hall effect sensor. Mine was not good looking and I had no codes and never had the in use light come on. Replaced it tonight and it cured all my issues.

I have a Rinnai tankless unit that is 5 years old. I am also on a well that has high mineral content. Not a good mixture. For two years it has become unreliable to deliver hot water. Last week had a tech flush the unit...or at least try to and now I have no hot water. The only advice I would have is change the little filter very often if on a well with hard water. For me, I have gong to abandon the unit and have a normal tank water heater installed. The Rinnai saves money to operate but not worth the trouble. Excellent video.

[@ThatTanklessGuy]

You will still have a problem with the sediment and minerals settling at the bottom of the tank. Here in Florida I put a pre filter on the incoming cold water and service them twice a year. Cost on fuel snd water savings will be great. Thanks for the comment Mike

I changed the old card with new one sitll no difference. thank you for your help.

[@rickevans5934]

Great information. Have you ever had an electric tankless, NOT turn off power to the primary element when flow is tuned off? This issue broke the flow sensor. Replaced the sensor and broke the new one, figuring out the issue. Third one is installed and working. Tested: elements, power, new flow sensor. I have not tested triacs or motherboard couplers. Most issues are no hot water. Mine is the opposite.

[@wadetharp348]

Great video. I have a RL94 model. Flow turbine was stuck. First video I saw said use compressed air to try and dislodge what might be sticking the turbine....no luck with that one. Your video showed me how to get access to the turbine in the first place, but still no joy doing anything one the two screw flange assembly (the one with the little screened filter) was loosened and the piping pulled over to the side. It still was not over to the side enough to give me full access. HOWEVER, I watched another video that saw me home free. It mentioned removing the 2-screw flanged assembly (unthread it) from the isolation valve assembly below it and it would give enough of an air gap to get to the turbine with some needle nose pliers. This allowed me to not have to break into the bowels of the RL94 unit. Cleaned out the turbine quickly and got back up and running in no time. Of all the videos i watched on this topic, yours was by far the most informative. Thanks for spending the time.

[@JoeBlowzir]

I know your original comment is a year old but just in case...could you please post a link to the video you reference, the one that gave you enough room to access the turbine with needle nose pliers? I could follow your directions but I'd like to see it done, too. Thank you.

Mike, I removed the water servo valve but the water flow turbine was stuck even with needle nose pliers, so I lubed with Pam, blew out with compressed air heard weeeeee then put back together; Do certain models retain the turbine? You indicated some did not come out and some do come out....???? Do I buy whole servo unit? When I pop sink faucet on/off quickly, the hot water flows within 3 minutes....If I just turn it on, nothing, no codes, no firing, no flames.... This is driving me crazy.

Yes that’s correct some do come out some don’t. It also could be a bag magnetic sensor that reads the turbine. You may have to replace the turbine. Mike

If I even crack the cold open in the shower in a minute or so the hot shuts down. Could it be back pressure? And the unit sits of due to low volume threshold hit? Would valves replacement possibly help or fix it?

Hi there my Rinnai Continuum Model 2532. I can not find any information for my problem. I go to use the hot water and nothing, i then checked the control panel in our master bath and there was nothing like no power. i checked the circuit breaker i checked for power at the unit and it was getting power. I checked bother fuses in the unit and they were good. is it the circuit board? or should i check something else? thank you

Sorry PC

[@michaeljulian2929]

Thanks for all the great videos!! I have a Rinnai RUCS75C that I am have an issue with. Sometimes when I turn the hot water flow on full the unit will fire up full blast and then after a few seconds it will loose flame on the outside burner section. It clicks like one of the four burner relays is turning off. When this happens the water flow will slow down to try to compensate for the reduced flame. I have pulled the flow turbine and inspected as you show and it is free and spins easily. Kind of at a loss any suggestions??

[@mccarseat]

Great video! I’m having an issue with my RUC98iN where since flushing the unit my low flow vanity faucets won’t trigger the unit to fire. Everything else in the house will, if I remove the aerators from those faucets the heater will fire and work fine. Could this be the flow sensor? I tried flushing it again, cleaning out the screen filter on the inlet side. No luck.

[@stevebodine1129]

Thank you very very much you were spot on took my tank apart and it’s back working

[@budgoetzinger7215]

Great videos!!! A question for you, my heater works fine except for water at the kitchen sink. Showers and a utility sink work ok but not hot water to the kitchen sink which is the farthest outlet from the heater. I flushed the heater with vinegar but no change. I'm thinking there is debris on the flow sensor that only happens when there is lower flow to the sink but not the higher flow showers? I didn't clean the inlet filter because the installers placed the power conduit right in front of it. 😡

[@mikee7532]

Hi Mike, thanks for the great details for the Rinnai's. I have reviewed your video on no flow, locked turbin, however, I have the other problem. We have the E110CN and, with no domestic water flow, the water heater plates are heated on low fire. Now, I see the turbine and the sensor, but, it doesn't seem logical that these would cause this phenomena. Any idea why this unit is behaving this way? It will even low fire and not allow the boiler heat to begin. Any thoughts?

[@joshuarideout1965]

Great video! Question: We have a RUC80 and are having an issue where the dedicated closed loop that goes to a forced air heating system fires the burner, but running the hot water from our taps does not. In order to get hot water, we have to turn our thermostat up a few degrees, wait for the burner to kick in, and we can get tap hot water. Then when you are finished your dishes/shower, you turn the thermostat down again. But you could run the tap all day and no hot water, no error code, nothing. How could this occur, is it the water flow turbine as well? Thanks.

[@AaronWiggin]

Mike - Thank you for the videos. I was able to troubleshoot, disassemble, clean, reassemble the flow turbine and reinstall. Fired it up and had hot water again. Had a bit of a surprise when it a leak appeared but luckily it was just a pinched O ring I didn't see on the hotwater out. Would a prefilter help keep the screen clean?

[@joshualo241]

Wanted to leave an update here as I figured out that the position does matter. I opened up the motor assembly and saw a mechanism that appears to identify it's state. My theory is that an external controller tells the motor what state it should be in (high, med, low) and the motor just rotates itself until it's in the correct state. There's no feedback from the actual flow or valve so you do need to sync the valve and motor state. When reassembling I opened the valve all the way and adjusted the state mechanism to match based on the rotational direction of the knob. Hopes this helps someone in the future!

my v75i e is throwing a 65 code. I cleaned the filter as well. The weird thing is if i hold the T&P valve open the heater fires up without coding. I then open up all the faucets in the house and close the T&P the water heater continues to run. Once i shut off all the fixtures then turn one faucet on it will throw code 65 again. I have 50 psi going into & out of the Rinnai. Its acting like it wants to run only on less psi since it runs fine with either the T&P wide open or all the fixtures running.

[@ThatTanklessGuy]

The T&P is rite off the tankless snd makes the unit fire at high fire. One question if you turn all the hot water faucets on in your house does it give the code. Sorry second question lol how old is the unit snd have you serviced it every year. It really sounds like you have a stuck or bad water servo valve. If the unit is under 5 years old the part is under warranty. I hope this helped Mike

[@chadede9694]

@@ThatTanklessGuy Thank you for the quick response. The unit is brand new. The only way we can keep the water heater from throwing a code is first open the T&P then we can open all the faucets. If we try to open the faucets first the water heater will code. Its almost like it doesn't want to fire correctly with full water pressure which is 50psi. Its weird that it will fire with the T&P wide open creating a pressure drop

I have searched over 100 combinations of "What does a Rinnai Tankless Water Heater Sound Like?" To my incredible surprise, THERE IS NOT ONE VIDEO IN THE WORLD ON LINE SHOWING THIS SYSTEM ACTAULLY RUNNING. WIll somebody please take a video of this thing ACTUALLY RUNNING! My system works fine, but it sounds like a small vacuum when the exhaust fan kicks on. It is kind of loud. I am wondering if this is normal.

Keywords matter “Rinnai Tankless Water Heater Makes Loud noise”. Now what videos pop up

Thanks .My wife is so happy to have a hot shower on the weekend after I found grit in the flow sensor.

[@mdforseth]

The official Rinnai video says to remove the filter, rinse it clean, then reinstall before de-scaling; then remove, rinse clean, and reinstall again half way through descaling.

[@ThatTanklessGuy]

There wrong you want to have the inlet fully open to get the most solution through the heat exchanger. There is a lot of things Rinnai has on their site that are wrong. Remember there in a lab, I'm in the field lol

So comparing Rinnai to other brands of Tankless Water Heaters on the market -- Why Rinnai? All of your videos are great but it does seem you talk a lot about maintenance and repairs on the Rinnai tankless heaters!

[@ThatTanklessGuy]

I talk Maintance so people know what has to be done on them to last the 20 years if maintained properly. There are also units installed incorrectly I’m trying to let people know what has to be done to repair them

@@ThatTanklessGuy so part of my question was why the Rinnai tankless over anything else like a Rheem et all?

[@johnscurlock9402]

This video saved me ~1000$ today. I was able to remove both the inlet side of the fitting and the water flow sensor side of the fitting without disconnecting any wires, I was able to clean the flow turbine and reinstall the whole thing. Everything worked flawlessly afterwards. The hardest part was removing the wire spring clip that holds the turbine in the flow sensor body. In any case, thanks so much your video and explanation is truly appreciated.

...what were your prior issues beforehand? My Rinnai V53DEP outdoor has no water coming out....tried everything so far...."within my scope that is..."

[@Abbey6510]

How did you remove the clip
