What Does Error E1 Mean?

The Electrolux water heater E1 error code indicates a malfunction in the temperature sensor, often leading to the failure to heat water. Symptoms include the display showing E1 shortly after a heating request and the unit not reaching or maintaining the desired water temperature. Unusual clicking sounds may also occur during operation. This issue is commonly caused by a faulty inlet temperature sensor or damaged wiring, disrupting the heating process.

Common Symptoms:

  • Display shows E1 shortly after a heating request and the water heater does not heat.
  • Water heater fails to reach or maintain desired water temperature, potentially leaving cold water.

Possible Causes

  • Faulty inlet temperature sensor (thermistor) (medium)
  • Loose or damaged wiring to the temperature sensor (medium)

How to Fix Error E1

DIY Fix Basic checks before calling a technician

  1. Power cycle the water heater (turn off at breaker, wait a few minutes, then turn back on).
  2. Ensure the water heater receives proper power supply.
  3. Check for any obvious loose wire connections at terminals accessible without opening the heater cover.

Technician Only Inspect and service temperature sensor and wiring

  1. Disconnect power and water supply.
  2. Access the inlet temperature sensor location according to Electrolux model safety guidelines.
  3. Test the thermistor/temperature sensor with appropriate tools (e.g., multimeter) for proper resistance response.
  4. Replace the temperature sensor if faulty; inspect and repair wiring harness for damage or corrosion.
  5. Verify proper reconnection and test the heater operation.

Parts needed: Inlet temperature sensor (thermistor), Wiring harness/connectors

🛑 When to Call a Pro:
  • If the E1 error persists after basic resets and checks.
  • If there are signs of water leakage, electrical faults, or unusual smells.
  • If you are unsure about safely accessing internal components.
