Error codeHd / HO
ApplianceDishwasher
Heat delay: what the display is telling you
Water has to be warmed before the wash starts, and Hd marks that wait. Some displays show the same message as HO. Frigidaire’s wording is “heater on mode activated”.
Does anything need doing?
No steps are listed. The owner guide gives no checks for this message, so it reads as a status rather than a fault.
If the display shows something else
CL points to a door that is not closed and latched.
A different message or a cycle that never gets going can go to Frigidaire dishwasher repair for the Bay Area, or ring (415) 319-6371. Give the model number and say what the display showed.
Model compatibility: Frigidaire 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
Hd or HO is a heat delay while the dishwasher warms the water before washing.
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.
