E1 · Water supply error

Safe first steps

1. Ensure the water inlet valve is fully open.
2. Inspect the external filter of the inlet hose for blockages and clean it if necessary.
3. Check the inlet hose for kinks or damage that may restrict water flow.
4. If the error persists after checking the valve and filter, inspect the water supply line for leaks or blockages.

When to stop

• Stop if you see water leaking from the inlet hose or connections — risk of flooding.
