Classeq dishwasher not draining fully; dirty water remains in the tank after the cycle ends, but no error code is shown.

Safety first: Turn off power before accessing the sump or pump.

• Clean internal filters: Remove and thoroughly clean all tank filters and strainers. Ensure they are seated correctly.
• Inspect sump and pump inlet: Check the sump for debris such as glass, labels, or food waste that could restrict flow to the drain pump.
• Check drain hose and trap: Follow the drain hose to the sink trap or standpipe. Remove and clean the trap. Ensure the hose is not kinked and that the outlet height meets Classeq installation guidelines.
• Test drain pump: Listen during drain phase. If the pump sounds weak or intermittent, remove and inspect the pump for partial blockage or wear. Replace if necessary.
