Customer Question

newly installed 6 weeks ago 222F DHW only ran ok until I had a shower today at 5 o,clock, ended up with a cold rinse. looked at settings all seems ok but no flame. pushed reset upped tank temp to 130 timer on automatic mo-so. wants to start, sounds like venting motor starts up then shuts down after a few seconds.

It should still be in warranty, what did the dealer offer to do about it, These are very complex units trouble shooting can be arduous a process you want to avoid if possible

Meantime turn the shower on, and two other hot taps at the same time and tell me if the problem persists, this is a test for sufficient water flow to run the unit and of the flow switch and cold water inlet screen.

We can go from there
