not all the time but some times during drying the tumble dryer starts bleeping and shows code 002 on the display and I have to turn off and back on again and it clears code and I can re-start it and it finshes drying
Yes it is a complete nightmare I even called Miele and they could not tell what the fault code is all they wanted was to send a engineer out...
One thing I can tell you as I have fully stripped mine down it is not lint build up on the coil or drain it seems like it is getting to hot due to not enough air circulation as there is a sensor under the filter.
