My water heater was installed about 6 years ago and have had no problems until recently. We get a Error Code 045. When I look it up is says "Abnormal Bypass mixing valve". Action is: "Check the bypass mixing valve".
We still have hot water and seems to run normally. I have unplugged the system and then plugged it back in and it will stay good for a little while. I did it the next time and went right back to the error code.
System still runs perfectly.
What to do?
