Miele WT945 Dryer Problems - stage by stage fixing (Introduction)
After two years of regular dryer fan seizure, and having called out a Miele technician to fix an unrelated problem on the WT945 (main water heater shorted), I pumped him for more information on the dryer side of things. I have to say he was extremely helpful and straightforward with his advice. So – with much help from the expert – I’ve attempted a complete summary of the dryer problem and its various solutions, which hopefully may be of interest to fellow sufferers. Good luck!
Dryer fan seizure seems to be a common problem with the WT945 as it ages. The symptom is (usually) a flashing ‘dryer’ light on the front panel and wet, cold clothes instead of a good drying cycle. If you’re familiar with your Miele sounds, there is also the absence of the high-pitched fan motor noise when drying (although the main drum still ‘tumbles’).
Before you attempt a fix, please be aware of safety issues. If you’re not confident about working on mains appliances with large, heavy moving parts, I would not recommend moving beyond Stage 1. In any case, always work with the power off, and beware of the heater (the long rectangular box sitting on top of the drum) – it can get very hot indeed.
First understand your components. When you take the top off the machine (screws under white plastic caps on each side of the top, about 5 cm in from the front), you will see a very obvious electric motor at the top rear right corner of the unit. This is the fan motor, which (through a rubber belt) drives a shaft that goes into a much larger, flattish unit bolted onto the back of the drum. This larger unit is the ‘fan box’, and hidden within it is the dryer fan that moves the air that does the drying (similar to a hairdryer). The small nylon ‘fan’ mounted on the front of the motor shaft (which cools the motor itself) is a red herring – this isn’t the fan we’re concerned with.
You will undoubtedly drop tools into the machine at some stage. Don’t panic and don’t mess about with magnets on strings etc – it’s far quicker to open the whole front panel which hinges on the right like a door. Take out the detergent tray, undo three Torx screws revealed around the edges of the tray holder, undo the three bolts behind the main door of the machine (these aren’t as fundamental as they look – nothing is going to fall off!). Open the filter flap and unclip the filter drain outlet from the inside of the flap. Open the door by breaking the seal and overcoming the spring clip at the base of the left hand side (can be quite stiff). Access is now pretty easy to the ‘floor’ of the machine to retrieve your tools. When closing the front again, don’t forget to feed the emergency door release plastic tab through the hole at the top of the filter flap aperture, otherwise it will be hidden inside the machine next time you want to use it.
