Clear the message
Press any button to clear F11 from the display.
-
Clean the filters
Lift out the coarse filter and empty it, then remove and rinse the fine filter. Refit them and check the filter handle is locked in the stop position.
-
Unblock the drain pump
Turn the dishwasher off at the main power switch and unplug it. Remove the filters, scoop out the water, remove the colored stop on the right in the bottom drain, and turn the pump wheel by hand to remove any items.
Safety: Unplug the dishwasher before reaching into the drain. Watch for broken glass.
-
Refit the pump stop
Put the drain pump stop back, then the fine and coarse filters. Asko notes the stop must not be left out.
-
Check the drain hose
Make sure the hose has no kinks or sharp bends. Loosen it where it ends and check it for debris, then run a rinse to test.

Call Asko if it stays
If F11 returns, call the Asko Customer Care Center.
When to call a technician
If F11 returns with clean filters, a clear drain pump and a free hose, Asko says to call its Customer Care Center. A failed drain pump or control fault needs a technician.
Questions people ask
Is F11 a water inlet problem on an Asko dishwasher?
No. Asko's manual lists F11 as a water outlet fault. Water inlet faults are F12 and F67.
How do I reset an Asko dishwasher with F11?
Press any button to clear the message, then fix the drain problem. The code returns if the water still can't drain.
Why does it whir but not start after I cleaned the pump?
Asko says a whirring sound with no start means the overflow protection has triggered. Shut off the water, unplug the unit and call Customer Care.
