Miele t494c clean out aiways light on after every cycle

It sounds like the dryer is heating again, but the machine still thinks airflow is restricted or the laundry isn’t drying as expected. On these Miele dryers the “Clean out airways” lamp can be triggered by more than just fluff build-up.

1. Isolate it from the mains first before removing any panels or checking internal parts.

2. Re-check the full airflow path, not just visible fluff: - lint filters and their seals - condenser unit and condenser housing - fan impeller and fan housing - all internal ducts, especially where they rejoin after the rebuild Even a slightly misplaced duct, seal, or cover can reduce airflow enough to trigger the lamp.

3. Check the fan is actually moving plenty of air: - strong airflow from the outlet - fan wheel tight on the motor shaft - no broken or cracked impeller blades

4. Since you replaced the drum sensor brushes, re-check their fitting: - correct parts - properly seated and making contact - wiring firmly connected On some dryers, poor moisture sensing can make the machine run incorrectly and bring that warning on.

5. Check the thermostats/temperature sensors and wiring around the heater housing. If one was not changed, it may now be drifting out of spec rather than fully failed.

6. Make sure the condenser is genuinely clear internally. They can look clean but still be partially blocked with residue.

If everything is clear and correctly reassembled, the most likely causes are reduced airflow from a sealing/duct issue, a fan problem, or a sensing/control issue rather than a simple blockage. If you need live electrical testing, it’s best left to a qualified appliance engineer.
