On Demand Water Heater Issue
I have a Girard GSWH-2 water heater. Its 2 years old and we have had no issues with it until this weekend. After a few hours are hard rain, when I tried to use the hot water i received an error code "E7" on the control panel.
E7: Linear valve failure:
The Controller Module detects an open circuit in the Linear Valve control circuit before ignition or during normal operation indicating a faulty Valve.
After about 18 hours of nicer weather, I had hot water and no error codes. I did not do anything to correct the issue, other then stare at the heater a few times.
I was wondering does anyone have any idea what may be happening?
Thanks in advance for your assistance.
