How to Fix / Troubleshooting

Safety: Turn off power and allow the tank to cool before working.

Steps:

  • Access element terminals: Remove the lower cover to expose the heating element assembly.
  • Check wiring: Ensure wires are firmly attached to the element terminals and not burned.
  • Test element resistance: Disconnect wires and measure resistance across the element. An open circuit (OL) indicates a failed element.
  • Replace element: Drain the tank, remove the flange, and install a new Eldom-compatible element with a new gasket. Refill and bleed air before restoring power.
