Error codeF41

What F41 signals
Asko labels F41 as heater fault 1 and lists it for the DBI564 series. The heater is the part that warms the water, so the fault concerns heating.
What the manuals say to do
DBI564 manual
Turn off the water supply valve and pull the plug of the machine.
DBI565 manual
Start with the Self-cleaning program using citric acid. Put two tablespoons of citric acid in the detergent compartment and leave the dishes out. If F41 persists after that, close the water supply valve and unplug the machine.
A technician visit is the step after either route.
Codes to look at next
F56: circulation pump fault, part of the wash circuit
To book Asko dishwasher service in San Francisco or the wider Bay Area, phone (415) 993-3547. Mention F41, say whether the citric acid cycle was run, and have the model number to hand. See Asko dishwasher repair for a summary of the work.
Model compatibility: Asko reuses codes across series and model years, so F41 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
