SOURCE: Noritz tankless water heater not producing hot water

I called Noritz error code 16 is a overheat problem. Noritz say's to flush your coil with vinegar or CLR.
Use a small pump to recirculate the CLR or vinegar through the system for 45 minutes and flush with fresh water. This worked for me.

did you check the filters on the the water valves, i am not exactly sure about your codes that are shoeing but if you could read it and post them, i know on some of the units 76 means there is low water pressure and the filters are behind 2 caps one on each side above the shut off valve take off the caps and remove the screens, clean them and replace them ,, make sure you turn off the water on both side first or you will get wet

SOURCE: what is error code 59 on a noritz tankless water

The 59 code is typically caused by insufficient gas supply to the unit. It can also be caused by obstructed exhaust flow, stuck exhaust damper (located directly on top of the unit's exhaust), insufficient makeup air, or improperly installed venting (i.e. too long or too many elbows).

I would recommend initially checking the incoming gas pressure at the gas connection on the unit. The gas pressure should not drop below 5" water column for a natural gas unit, 8" for a propane system (the unit need to be operating at its maximum output).

SOURCE: My Paloma tankless water heater flashes C2 11 error code

I just had the same problem and I fixed it in about an hour or 2. First shut off the gas,water and power(unplug it) Take off the cover There are about 20 screws above the electrical circuit board. You have to remove all of those screws to remove plate that is covering the burner assembly. The burner assembly has these 3 pins that look like number 7's these are covered with build up and gas can't flow right. That's why you get the c211 error not enough gas. Take a wire brush and gently remove any build up, I also cleaned the thermocoupler which is next to the burners. It looks like a metal pin with a couple of wires coming out of it this was also very dirty. I took a can of air and basically freshened it up It works perfect now. Email me with any Q's at [email protected] Good Luck All that you need is a long phillips screw drive and a drill because its about 25 screws
The burner assembly has 2 screws all the in back underneath the assembly once you remove those 2 the assembly comes out . You don't have to disconnect any wires.

SOURCE: Paloma tankless, gas, water heater, error code C7 76

If you look on the left hand side of the burner control module you'll see 4 capacitors - the capacitors have most likely failed...pretty sure anything code 76 is P/S failure. It may also be covered for manufactures defects. If the cap is blown..the top will be slightly raised as apposed to flat like the other nearby caps - they are called top blow capacitors...the damage should be evident.

I have takagi TK3 tankless water heater humming and rattling noise issue at start up.


Sounds kinda lame, but check every nut, bolt and screw on the heater and where it fastens to the wall. something may simply be loose!

Takagi t-k3 runs hot on low to med flow on high turns cold & flame shuts off


OMG 95 PSI is too high a pressure for a tankless! What was the W.C. in inches on the manometer?
Also on a T-K3 12 isn't a Code but a partial Code. You need an R/C to make this easier as counting led flashes produces wrong codes.
you'll have to find the correct code it's throwing not a partial.
And put a Pressure Reducer on this to below 60 PSI. 95 PSI is only impressive when it blows the tubing out after a few years.
Call Takagi in California not A.O. Smith in TN and they'll help someone fix this

My Takagi TK3 isn't heating as it should. Had a tech out and he adjusted the dip switches to 140 degrees, which worked for a while but now it barely heats to 100 degrees. Gas flow rate appears to be...


Is tankless computer older than 5 years? Imagine how well a 5-year old laptop computer works.

Setting temperature to 140 degrees might be the basic problem:
Read following resource:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html#temperature

I doubt this Takagi computer unit was maintained as shown in product manual, and that heat exchanger was not delimed each year as shown in product manual. So the heat exchanger is probably heavily coated with un-removeable scale... since yearly deliming will not fully remove scale on tankless units, the tankless computer is designed to sprial downward in efficiency despite glossy brochures that promise endless and effortless hot water for 20 years ... as if any computer will last 20 years:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html#de-lime

Since you are not getting error code, the problem might be crossover, or some other plumbing problem:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html#no-error
http://waterheatertimer.org/Crossover.html

I always recommend replacing tankless computer with tank-type water heater for $385 for same-day do-it-yourself solution and to save the endless expenses that arise with computer-driven water heaters.

991 error code on a Takagi T-K3 Flash gas tankless water heater


Re- set code!!!!
We have a Takagi TH3 DV 540 model.Air intake got blocked with snow, condensation etc.Once we cleared that then you just have to re-set it to clear the 991. On our model there are 4 tiny buttons across the bottom (Take off front cover) to find them. of the computer board assembly bottom left corner. Push the two buttons on the right simultaneously hold for 15-20 seconds or so, then turn the Takagi off then on again- should work now!
If you have a different model then those buttons will be in the bottom left corner still but running vertically- try doing as above with the bottom two buttons. We had to go without heat and hot water for 2 days until we could get hold of someone to tell us this. We called Seneca Supply 716-852-4744. Good luck

My Takagi T-K jr. keeps flashing an error code 21....the water turns cold and we shut it off ....wait a few...then turn it back on....works for a little then wil flash again...have replaced the pressure...


In my case, the error code 21 was caused by the failure of the vent fan to run-on after shut off (easily verified by listening to the unit). The problem was not resolved by swapping either the fan or the control unit with another heater. I talked to a local service tech who had a couple of suggestions. One was to move DIP switch #6 to the upper position. After doing thisit will be necessary to re-initialize the controll by cycling power off and on. This fixed the problem. I emailed Takagi tech support to ask if I should consider this as permanent fix, or if there was something else I should do. Since I got no reply, I'll pass on the tech's other suggestion: buy a Rinnai.

My Takagi T-M1 water heater is not functioning. After less than a minute of operating it stops and the red light in the front is blinking.


I HAD THE SAME PROBLEM. I CONTACTED TAKAGI WHO SENT OUT THE REPLACEMENT PART. AFTER INSTALLING THAT PART, IT WORKED FOR A MINUTE AND STOPPED. I CONTACTED TAKAGI ONCE AGAIN AND WAS TOLD "OH, THAT MOTHERBOARD GOES OUT SOMETIMES IF THAT FIRST PART GOES BAD!" THEY THEN SENT OUT A NEW MOTHERBOARD WHICH FIXED THE PROBLEM.

Pilot fires then quickly shuts off how do I pull a code on a Takagi T-K2?


Pilot must heat the thermocoupler a couple of minutes before letting go of the button. The coupler controls the main valve.
