Dishwasher completes cycle but dishes are cold and not properly washed; E6 appears related to temperature sensing.

Safety first: Disconnect the appliance from mains power before accessing internal components.

• 1. Confirm symptom: After 20–30 minutes of a wash cycle, open the door carefully. If the water is cold and E6 is logged, the temperature sensor is suspect.
• 2. Locate NTC sensor: On many Finlux models, the NTC is integrated into the circulation pump or heater housing at the base. Remove the lower front panel to access.
• 3. Check connections: Identify the small two-wire connector for the NTC. Unplug and inspect for corrosion or moisture. Dry and reseat the connector firmly.
• 4. Visual inspection: Look for damage to the sensor body or wiring harness. If the sensor is cracked or wires are frayed, replacement is required.
• 5. Test run: Reassemble and run a short hot program. If E6 returns, the NTC sensor is likely defective and should be replaced. If a new sensor does not resolve the issue, the control board may be faulty.
• 6. Technician involvement: Measuring sensor resistance and confirming PCB faults requires a multimeter and expertise; contact a technician if unsure.
