GSWH-2 Gerard Tankless water heater user control panel
Our RV occasionally not very often has a issue where the control panel goes blank like no power, it has sometimes lasted as much as 8 hours in the condition before it's back on. No faults are seen on the control board normal green led. What does the actual on/off button on the Control Power do? It seems to have no effect. Thanks
i have the same issue in Sprinter 24HL...control panel is dead...power on outside tankless unit is on, but nothing on control panel. How do i remove the control panel inside the coach to check the wiring?
