Error codeHd / HO
ApplianceDishwasher
Quick answer: nothing is broken
What you see: Hd, which may also be written HO
What it stands for: heat delay, the heater on mode being active
Is it a fault: no, it is a status message
Why it shows: the water is being brought up in temperature before the wash begins
Why the wash has not begun yet
An Hd display means the dishwasher is still warming its water, so it has not started washing. Once the heating stage is over the cycle moves on by itself. There is nothing to reset and no part to blame. Electrolux owner support describes this entry in its US dishwasher guide, and it belongs to current-generation machines.
When the display reads something different
Do not assume the worst from an unfamiliar message. Look it up first. Three other entries in the same guide are often compared with Hd:
Er13: the control has lost its state machine, a system wide fault
i10: a water supply problem, either too little water or no incoming supply detected

Model compatibility: Electrolux reuses codes across series and model years, so Hd / HO may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Heat delay (heater on mode active) while the water is warmed before washing; a status message, not a fault.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
