SOURCE: My Takagi T-M1 water heater

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.

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!

Code 211 comes on but vent is clear of any debris or blockage. Sometimes can go days without alarm sounding sometimes alarm sounds 3-4 times in 10 minutes.


Generally tankless must be maintained on yearly basis.
Error codes are usually stored in the computer memory until they reach a threshold and then the error code is displayed... it is possible the control board is bad.. or the sensor that feeds information to the control board is bad.
Contact manufacturer or installer.
Contact local service technician who is qualified on that specific brand.

Takagi code 541


Code 541 means the 2 way valve is not turning, that could be the valve has build up calcium due to hard water and the attached motor is not able to turn it, or the motor is broke or finally the controller (Compute Board is defective).
The 2 wau valve sits behind another valve when looking at the unit on the left hand corner, it must be taken out first to gain access to the 2 way valve.
The 2 way valve motor can be seperated from the valve by two screws and the valve can be manually opened but turning it to the horizantal position, there is a pin on that shaft.
Turn kon the heater then but leave the motor connected, if the motor turns for short time then the PCB is most likely ok. This usually indicated that there is too much of build up inside the valve. If the tankless was properly with bypass valves (outside of the unit) installed then this can be easily fixed.
Turn the unit off and run with an external pump and bucket with vinegar for about 30 minutes by using the bypass valves. This will clean the 2 way valve from inside and should turn then easily and the motor will be able to control it. This is usually beyond the DIY scope, call a real pro for that.

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.

Turn on power,15-20 seconds later,get error code 991, abnormal or imperfect combustion. natural gas at 7 on the water column, filter clean. other contributing factors for this code? can hi-limit switch...


Hi,
First things... you have checked the inler filter andthe gas pressure, but have you checked and cleaned the thermistor(s)??? Also the flame sensor... clean that with a soft cloth...
Next turn down the temp with th dip switches that should tell you if it is the high limit...
Has the unit been cleaned with vinegar or CLR lately or ever??? there maybe buildup internally in the unit...
Is the flame a nice blue color or is it yellow???
Does it go out just before the unit cuts out???
Do the flames lift from the burner???

These are all things that I would be checking if I was coming to your home to check this unit...

Comment back with any other questions or comments...

to clear the 991 Takagi code, simultaneously press the bottom 2 grey buttons of the four just to the left of the flashing LED light. When the LED stops flashing, release and then press the reset button on the black panel about 8 inches above that
