What the HO error code actually means

The HO display means your dishwasher noticed that the water wasn't hot enough to clean properly, so it's automatically adding extra time to the cycle to heat the water up. This is normal behavior and not an error. The cycle will continue on its own once the water reaches the right temperature.

Questions people ask about HO

What does HO mean on a Electrolux dishwasher?
HO stands for Heat delay on an Electrolux dishwasher. It means the control board has detected that the water temperature is not yet high enough and has extended the cycle to allow time for heating. This is a built-in feature designed to protect wash performance, not a fault or error condition. The cycle will resume normally once the target temperature is reached.
Is it safe to use my dishwasher when it shows HO?
Yes, it is safe. The dishwasher is simply pausing to heat the water to an appropriate temperature before continuing the wash cycle. There is no risk to the appliance or your dishes during this delay. The machine will proceed through the rest of the cycle automatically.
How much does it cost to repair an Electrolux dishwasher that keeps showing HO?
If the issue is a failing heating element, replacement parts typically range from around 30 dollars to 80 dollars depending on the model, with professional labor adding roughly 100 dollars to 200 dollars. A faulty thermistor is generally a lower-cost repair, with parts often in the 20 dollar to 50 dollar range. If the control board is at fault, costs can be considerably higher, sometimes reaching 150 dollars to 350 dollars for parts alone.
How do I fix the HO code on my Electrolux dishwasher?
In most cases, no repair is needed since HO is a normal status indicator. You can reduce its frequency by running hot water at the sink before starting the dishwasher, and by making sure your water heater is set to at least 120 degrees Fahrenheit. If the HO state persists for an unusually long time or appears on every cycle without resolving, inspect the heating element and thermistor for faults.
Will resetting my Electrolux dishwasher clear the HO code?
Resetting the dishwasher will cancel the current cycle and clear the display, but it will not address the underlying reason the heat delay occurred. If the water supply is still cold or a component like the heating element is faulty, the HO condition will return when you run another cycle. A reset is only useful if you want to restart the cycle, not as a fix.
