How to Fix / Troubleshooting

Safety first: Disconnect power and water. Use towels to contain any leaks.

  • Pull out dishwasher: Carefully slide the Summit dishwasher out from the cabinet to inspect the sides and rear.
  • Inspect hoses: Check the drain hose and any internal circulation hoses for cracks, pinholes, or loose clamps. Tighten or replace as needed.
  • Check sump and pump: Examine the sump assembly and circulation pump for signs of leakage around seals. Replace the sump gasket or pump seal kit if leaking.
  • Test after repair: Run a short cycle while observing the underside for any remaining leaks before pushing the unit back into place.
