Display shows E15; unit may lock out and not restart until power is cycled

Critical safety warning: A ground fault can cause electric shock. Immediately turn OFF power at the breaker and do not operate the heater until the fault is corrected.

Steps:

• 1. Inspect for leaks: With power OFF, remove the cover and look for any signs of water leakage around the tank, piping, or heat exchanger. Repair leaks before proceeding.
• 2. Dry the unit: If moisture is present, dry all components thoroughly and allow time for complete evaporation.
• 3. Check element insulation: Disconnect heating element leads and measure resistance between each terminal and ground. A low resistance indicates a ground fault; replace the heating element.
• 4. Inspect wiring: Look for damaged insulation or wires touching the metal chassis. Repair or replace as needed.
• 5. Test with GFCI/RCD: Ensure the circuit is protected by a functioning GFCI/RCD device. Reset it and test.
• 6. If E15 persists: The internal ground fault detection circuit may be defective, requiring PCB replacement.

Professional help: Due to shock risk, have a licensed electrician or authorized Electrolux technician verify repairs before returning the unit to service.
