Asko Dishwasher F5 Error: Wash motor fault
Asko dishwasher F5 error is a common issue reported by Asko appliance owners. What Does Error Code F5 Mean on an Asko Dishwasher? Error code F5 on Asko dishwashers — including D5000, D5100, and DBI series models — signals a fault with the main wash circulation pump or its motor. This pump is responsible for […]

Answer to continue safely
Is it safe to keep using?
No. The dishwasher will not clean dishes without a functioning wash pump. Repeatedly attempting cycles with a jammed or failed pump risks permanent motor damage.
Can I reset the code?
Yes. A power-cycle reset clears F5 from the display. If the underlying cause — jammed impeller or motor fault — is not addressed, the code will return within minutes of starting the next cycle.
When to stop immediately?
Stop if you notice: The pump makes a loud grinding or burning smell during start-up attempts, No obstruction can be found in the pump inlet yet F5 continues to appear.
Symptoms You May Notice
Dishes come out completely unwashed with dry detergent still in the dispenser
The wash pump never circulated water through the spray arms, so the detergent tablet did not dissolve and dishes received no spray cleaning action.
A humming or grinding sound followed by the cycle stopping
The pump motor attempts to start — producing an audible hum — but stalls against a blockage or due to electrical failure, triggering F5 and halting the cycle.
Cycle stops within the first few minutes and F5 is displayed
F5 typically appears early in the main wash phase, shortly after the machine has filled, as the controller detects the pump has not reached operating speed.
Spray arms remain stationary during the wash cycle
On machines where you can observe through the door, the spray arms do not rotate at all because no circulating water pressure is available to drive them.
Possible Causes
Foreign object jammed in pump impeller
A hard item has passed through the filter and lodged in the pump impeller, mechanically preventing it from rotating and causing the motor to stall.
DIY PossibleFailed wash pump motor or capacitor
The motor windings have burned out or the start capacitor has failed, preventing the pump from drawing and circulating water.
Requires ProfessionalLoose or corroded pump wiring connector
A wiring harness connector to the pump motor has vibrated loose or corroded, causing an intermittent or permanent open-circuit fault that the controller reads as a pump failure.
DIY PossibleSafe Checks You Can Do
-
1
Inspect the pump inlet for foreign objects
Remove the lower basket, lower spray arm (pull straight up), and the filter assembly. Look into the circular pump inlet opening at the sump base. Use a torch to spot any debris. Remove any objects with long-nose pliers. Replace all parts and run a Normal cycle.
Common culprits are toothpicks, small bones, broken glass, and olive pits. Always load cutlery handles-down in the basket to prevent them falling into the sump.

Check and clean the spray arms
Remove both spray arms (lower arm lifts off; upper arm unscrews counter-clockwise). Rinse under water and use a toothpick to clear blocked spray holes. Ensure both arms spin freely on their hubs with no cracked sections. Reinstall securely.
Blocked spray arms make the pump work harder and can contribute to F5 by increasing pump load.

Reset and run a test cycle
Turn the dishwasher off at the power button and wait 60 seconds. Turn it back on and select a short cycle. Listen for the wash pump starting — a steady rushing-water sound within the first 2–3 minutes confirms the pump is running.
If the motor hums for a few seconds and stops again, the impeller is likely still obstructed or the motor needs professional testing.
When to Call a Professional
Contact a qualified technician if:
- Pump motor resistance readings are outside the specification range for the Asko model
- The pump impeller turns by hand but does not spin freely — indicating a bearing failure
- F5 persists after pump replacement, pointing to a faulty control board pump relay or triac
