Panasonic Extended Cycle Duration / Sensor or Heating Issue

Dishwasher runs for an unusually long time or seems stuck on one stage

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Low inlet water temperature, Heater not working efficiently, Dirty turbidity sensor, Control waiting for temperature or clarity threshold

Check inlet temperature: Run hot water at the sink before starting the dishwasher to ensure warm water enters.
Verify heating: Open the door mid-cycle (carefully) to check if water is hot. If cold, investigate heater and NTC.
Clean sensors: Clean the sump and filters thoroughly; some Panasonic models use a turbidity sensor in the sump that can be fouled by grease.
