  2. Check the water supply hose for any signs of damage or leaks. Ensure it is securely connected to both the dishwasher and the water supply.
  3. Examine the drain hose for kinks or blockages that could cause water to back up and leak. Clear any obstructions if found.

When to stop

  • If you find significant water pooling or if the leaks persist after checking the hoses, stop and call a professional.
