Safe first steps
- Check the water drain hose for any visible kinks or bends.
- Ensure the drain hose is not pinched or extended beyond acceptable limits.
- Inspect the drain hose for clogs by detaching it and checking for blockages.
- If the hose is clear but the error persists, check the drain pump for any obstructions.
- If the drain pump is visibly damaged or the fault persists after cleaning, arrange a service visit — do not run the appliance.
When to stop
- Stop if you see water leaking from the appliance or around the drain area — risk of electric shock.
