- Inspect the water supply hose for kinks or blockages.
- Verify that the water pressure is adequate by checking other taps in your home.
- If the water tap is open and the hose is clear but the error persists, consider checking the water inlet valve for issues.
- If the water inlet valve appears damaged or the issue continues, arrange a service visit — do not run the appliance.
When to stop
