Drying function does not heat; laundry remains wet after drying cycle; E06 displayed.

Safety first: Unplug the washer-dryer combo. Dryer components can remain hot after use; allow time to cool.

• Step 1 – Clean lint and condenser: Remove the lower front panel or condenser access (depending on Gram model). Clean the condenser unit and air passages thoroughly of lint and dust to restore airflow.
• Step 2 – Access dryer heater: Remove the top and/or rear panel to locate the dryer heater assembly, usually mounted in a metal duct with wiring and thermostats attached.
• Step 3 – Check thermal cut-outs: Identify the thermal fuses/thermostats on the heater housing. With a multimeter, test for continuity. A blown thermal fuse (open circuit) must be replaced; also correct any airflow issues that caused overheating.
• Step 4 – Test dryer heater element: Disconnect the heater terminals and measure resistance. An open circuit indicates a failed heater that requires replacement.
• Step 5 – Inspect dryer NTC sensor: Locate the dryer temperature sensor on the air duct. Test its resistance; it should vary with temperature. Replace if readings are out of specification.

If all components test correctly but E06 persists, the dryer heater relay or control circuitry on the main PCB may be faulty and should be checked by a professional.
