Customer Question

our Noritz shuts off every time I turn on the hot water. If I shut down all the circuit breakers and then turn them back on, the unit lights up but shows priority light and not the burner light. As soon as I turn on any hot water faucets, the lights go off and there is never any hot water.

It sounds like you may have a bad or just stuck flow sensor. Have you cleaned the water inlet screen?

Customer: replied 4 months ago.
I have no idea where the water inlet screen is.

Do you still have the manual or can you upload a picture of your unit
