Safe first steps
- Check if the water supply valve is fully open.
- Inspect the water supply hose for any kinks or blockages.
- Ensure the hose is properly connected to both the machine and the water supply.
- If the hose and valve are clear but the error persists, check for blockages in the machine's water inlet filter.
- If the filter is blocked, clean it thoroughly. If the error continues after cleaning, arrange a service visit — do not run the appliance.
When to stop
- Stop if you see water leaking from the hose or connections — risk of flooding.
Likely cause
The water supply is closed or there is a blockage. Check the water supply valve and hose installation.
