GSW Single Element Operation / Lower Element Failure

GSW electric water heater has hot water but recovery is very slow

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Burned-out lower element, Faulty lower thermostat, Sediment covering lower element, Incorrect wiring causing only one element to heat

Safety: Turn off power at the breaker and confirm with a tester.

Check wiring diagram: Compare internal wiring to the GSW schematic on the access panel to ensure both elements are wired correctly.
Test lower thermostat and element: Use a multimeter to verify continuity. Replace any failed component.
Flush sediment: Drain and flush the tank to remove sediment that can insulate the lower element.
Restore power: After refilling and purging air, restore power and allow several hours for full recovery.
