Electrolux dishwasher Hd / HO: heat delay or heater-on mode
Electrolux’s dishwasher code guide describes Hd/HO as a heat-delay or heater-on state used while incoming water is brought to the target temperature.
What this guide covers
Error codes: Hd, HD, HO
This guide follows a structured decision tree built from manufacturer troubleshooting information. It does not assume that the most commonly replaced part is the failed part, and it does not show an exact-fit replacement part unless model compatibility has been independently verified.

When professional diagnosis is the safer next step
A persistent heating delay that prevents normal operation should be checked against the exact model guide and serviced if needed.
Appliance Verdict stops before energized electrical testing, gas-system work, sealed-system work, and other checks that can create unnecessary risk. A technician can use the model, issue, and completed checks from the interactive diagnostic as a starting point.
Repair or replace?
A diagnosis and a repair decision are different questions. Once you have a real repair quote, compare the total repair cost with the all-in price of a comparable replacement. Warranty or protection-plan coverage, appliance age, reliability history, efficiency, and likely future repairs can all matter. Appliance Verdict’s interactive result includes a transparent cost comparison rather than a black-box replacement recommendation.
