How to Fix / Troubleshooting

Safety first: Disconnect power before accessing internal components.

Step-by-step checks:

Clean filters and sump: Remove and clean the filters and check the sump area for heavy soil that could coat the sensor.
Locate sensor: Many Thor Kitchen dishwashers have a combined turbidity/temperature sensor mounted in the sump or side wall. Inspect it for scale, film, or food residue and gently clean with a soft cloth and warm water.
Check wiring: From underneath, inspect the sensor connector and harness for corrosion or loose fit.
Run a hot cycle: After cleaning, run a hot wash with dishwasher cleaner to remove internal buildup.
Persistent error: If E6 returns, the sensor or control board may be faulty and should be tested and replaced by a technician.

Warning: Avoid using sharp tools on the sensor lens; scratching it can permanently affect readings.

Dishwasher displays E6; cycle may stop and water may remain in the tub or be partially drained.
