Safe first steps

- Check the water inlet hose for any kinks or damage that may cause continuous water flow.
- Inspect the water inlet valve for proper operation; it should not be stuck open.
- If the inlet valve is faulty or the issue persists after checking the hose, arrange for a service visit — do not run the appliance.
When to stop
- Stop if you notice water pooling around the dishwasher — risk of flooding.
