Question about Noritz Water Heaters
Replaced circuit board. The voltage across the blue/white reads about 100VAC and the voltage across the black/white also reads about 100VAC. Theres voltage on both sides of gfi. No readings the remote terminals. Help!!!
Try leaving the remote unplugged and unplug the unit for 10 seconds and plug only the unit back in. If you get hot water without the remote connected but nothing after doing the same thing with the remote connected then your remote may have shorted out. Otherwise your circuit board may have had a short. In which case, call Noritz for a replacement.

did you turn the unit off before hooking it up ? Any function on a tankless rennai the pwer has to be turned off and the priority button has to be pushed in,, if you have the manuel it tells you haw to do this,,

The easiest thing to do would be to call Bosch and just ask for a new heater for free. The other option is to call Bosch and have them send you all new elements. If there is power, there should be heat of some kind.
