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 any grease deposits.
- Step 2 – Spray arms:
- Remove and clean the 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 optimal cleaning performance.
