Safe first steps

  1. Turn off the dishwasher and unplug it from the power source.
  2. Check the water supply hose for any visible leaks or damage. If you find any, replace the hose.
  3. Inspect the area around the dishwasher for any signs of water pooling. If water is present, clean it up to prevent further issues.
  4. Reconnect the water supply and plug the dishwasher back in. Run a short cycle to check if the error persists.
  5. 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

  • Stop if you see water pooling around the dishwasher or if the water supply hose is damaged — risk of flooding.
