How to Fix / Troubleshooting
Safety first: Before touching the heater, turn OFF the breaker and verify with a tester that the unit is de-energized.
Steps:
- 1. Check breaker: At the electrical panel, verify that the dedicated breaker for the Electrolux water heater is ON. Reset if tripped; if it trips again immediately, stop and call a professional.
- 2. Inspect power switch: Some models have an external power switch. Ensure it is in the ON position.
- 3. Verify voltage at heater: With appropriate safety precautions, measure voltage at the heater's terminal block to confirm supply is present and correct.
- 4. Check internal fuse: Turn OFF power, open the unit, and locate any internal fuses. Test and replace with identical type and rating if blown.
- 5. Inspect wiring: Tighten any loose connections at the terminal block and look for burned or melted insulation.
When to call a professional: If the breaker continues to trip or you are not comfortable working with mains voltage, contact a licensed electrician or Electrolux service technician.
