How to Fix / Troubleshooting

Safety first: Turn off power and water supply before inspecting for leaks.

  • Inspect door gasket: Open the door and examine the rubber gasket around the tub opening for tears, flattening, or gaps. Replace if damaged.
  • Check bottom seal: Inspect the lower door seal or deflector for cracks or warping. Replace if worn.
  • Verify spray arm clearance: Ensure lower and middle spray arms are not cracked or warped and do not strike the door or racks. Replace damaged arms.
  • Check water level: If water level is excessively high, investigate inlet valve and pressure switch issues that could cause overfill.
