Safe first steps
- Turn off the water supply to the dishwasher to prevent flooding.
- Check the water supply hose for any kinks or blockages that may be causing continuous water flow.
- Inspect the connection points of the water supply hose to ensure they are secure and not leaking.
- If the hose and connections are fine but the error persists, check the water inlet valve for faults. If damaged, replace it.
When to stop
- Stop if you see water pooling around the dishwasher or if any connections are leaking — risk of flooding.
