How to Fix / Troubleshooting

Safety first: Disconnect power before deep cleaning internal components.

  • Step 1 – Deep clean filters and sump:
    • Remove filters and soak them in hot, soapy water.
    • Scrub the sump area to remove grease deposits.
  • Step 2 – Spray arms:
    • Remove and clean spray arms thoroughly, ensuring all jets are clear.
  • Step 3 – Hot cleaning cycle:
    • Run an empty hot program with a dishwasher cleaner or a cup of dishwasher-safe degreaser placed in the rack.
  • Step 4 – Detergent and program choice:
    • Use a high-quality detergent and select hotter, longer programs for heavily soiled loads.

Regular maintenance cycles help prevent grease build-up and maintain cleaning performance.
