Q:Purchased this tankless water heater unit about 4 months ago. About 3 weeks ago there was no hot water. Was told the warranty was only for the heat exchanger. Any tips other than hiring the technician to look into the possible cause/ issue?

Answer This Question

A:  It likely is the high temp cut off. Carefully open the unit by removing the top and bottom screws. If you are not comfortable, turn off the breaker to the unit. Inside on the top center there is a button. Press it to reset the unit. Restore power and it likely will work.

        Connected the water and power, turned the faucet on to check for hot water. It ran for about 30 seconds then the hot breaker opened up. It couldn't be reset. I had to uninstall (A bit of a major hassle), put in a bypass so I had water at all, then I took the unit back to Home Depot. I ordered a new one. I'm hoping it lasts more than 30 seconds. Deliver is a week, so I have no hot water until then.

        Provides warm water with the provided low flow faucet restrictor. Don't expect hot water…! I would buy again for use as a hand washing station.
