Electrolux dishwasher Hd / HO Status Message

Electrolux describes Hd or HO as a Heat Delay or Heater On mode. Colder incoming water can make this normal heating delay last longer, so the message alone does not establish a heater failure.

Applies to Electrolux dishwasher

What the appliance detected

Detected condition

The dishwasher is in Heat Delay or Heater On mode while it brings the wash water toward the required temperature.

What may contribute

Possible causes

  • The dishwasher may be heating water as part of normal cycle operation.
  • Colder incoming water can extend the heating delay.
  • A persistent display that never progresses may need model-specific service rather than an assumed heater replacement.

Start conservatively

Safe preliminary checks

Work in order and stop whenever a step is not supported by the documentation for your model.

  1. Record the exact display and model

    • Photograph the code or message before clearing it so the original display is preserved.
    • Confirm the complete model number and compare it with the Electrolux owner manual before using any model-specific procedure.

  2. Use only documented owner-accessible checks

    • Allow the dishwasher time to complete the documented heating delay rather than immediately resetting it.
    • Confirm the display is Hd or HO and not a different code with similar characters.
    • Check the exact owner manual for the selected cycle and normal heating behavior.

  3. Stop before internal diagnosis

    • If the condition returns after the documented external checks, request Electrolux support or qualified service.
    • Do not remove service panels, bypass the door latch, probe live voltage, or access pumps, heaters, wiring, controls, or other internal components.

Actions not recommended

  • Do not reach into wet areas while electrical power is connected.
  • Do not repeatedly reset a breaker that trips again or use a reset to conceal a recurring fault.
  • Do not replace a pump, heater, latch, control, sensor, or wiring part from the display alone.

When to stop and request service

  • The dishwasher never progresses beyond the heating delay after normal operating time.
  • A different fault code appears, the breaker trips, or there is burning odor or abnormal heat.
  • Internal heater, sensor, wiring, or control diagnosis would be needed.
