Customer Question

We have Renai water heaters that are about 11 yrs old. Just this weekend one of them disfunctioned. The grand kids would be showering and the water would go from warm to cold after a few minutes. They would reverse faucet and turn back to warm and it would return to warm and then in a few minutes would repeat the same problem. It would continue to repeat this pattern. I checked other faucets that work on the same rinnai unit and the same problem occurred.

I am a Rinnai factory trained and certified repair technician. What is the model number and are you getting any error codes?
