Possible Causes

One of multiple elements failed (dual-element tank), Thermostat set too low, Sediment reducing tank volume, Undersized heater for demand

How to Fix / Troubleshooting

Safety first: Turn OFF power before testing elements or thermostats.

Steps:

  • 1. Check thermostat setting: Increase the set temperature slightly within safe limits and test hot water duration.
  • 2. Test each element (storage models): Measure resistance of upper and lower elements. Replace any open or shorted elements.
  • 3. Verify thermostat operation: Ensure both upper and lower thermostats switch power correctly between elements.
  • 4. Flush sediment: Drain and flush the tank to restore effective volume.

Note: If hot water demand exceeds heater capacity, consider upgrading to a larger Electrolux model or adding a second unit.
