Safe first steps
- Turn off the dishwasher and unplug it from the power source.
- Check the water supply hose for any visible leaks or damage. If you find any, replace the hose.
- Inspect the area around the dishwasher for any signs of water pooling. If water is present, clean it up to prevent further issues.
- Reconnect the water supply and plug the dishwasher back in. Run a short cycle to check if the error persists.
- If the error E:31-00 appears again, stop using the dishwasher and check for internal leaks or damage — risk of flooding.
When to stop
