SOURCE: I have a bosch YS2433R 'Highflow' hot water

Solution for a code 10 or 99 (for my own reference as much as anything!)
Hit change and the down arrow on the controller for 3 seconds.
Wait for the controller to beep and display 00 before using the down key to display 93.
Hit the On/Off button until 000 is displayed on the screen.
Press change and down simultaneously and the controller should revert to the pre set temperature. Hey presto! Hot water!!!

I have Model PTG2-42PVN it shuts off and the remote flashes C7 and 76. What does this mean???


Could be the remote control. Disconnect remote and see if tankless works fine.

Probably bad PC board. Rheem will send new board and you can install yourself.

Bad PC board is kind of like the motherboard on your computer, so expect same level of performance after replacing motherboard ... which usually means the computer's days are numbered before another major problem.

Code C8-76?


PC board is probably bad.
Rheem, Richmond, Ruud, Paloma, etc will send you another PC board, and hopefully the success rate will equal success rate of replacing motherboard on your computer.

C4 flash 76


I had the same problem so i called Rheem at 1-800-432-8373 and spoke to a technition who told me that error code C4-76 meant that the mother circut board was shot and they were going to overnight me one and also send a contractor to install it all for free! Feel free to call them with the model number and serial number and they'll do the rest.

FLASHING CODE C-7 WILL WORK FOR A WHILE THEN STOPS


disconnect the remote and see if the unit works properly; could be lost comm. between the burner control module and the burner assembly.

If your getting error code 76; contact Rheem customer support at (800-432-8373) and notify them IF you are getting a code "76" error

FLASHING C4 76


Had a Ploma unit - same as Rheem. Not sure what C4 is...but code 76 is lost comm between the remote control and the burner control module. Unplug unit = take front cover off...their should be a square circuit card assemble in front of you. Top blow capacitors are typically used in todays electronics, and they have an obvious curve if the capacitor is blown. If the caps appear swolen on the top they are blown. STOP! If your unit is less than 5 years old..contact manufacturer for defective power supply. This particular problem is known to the MF...If you have a Poloma/Rheem they send you step by step instructions on how to replace this board yourself...if you're slightly technical you can do this repair yourself.
