    Great explanation and easy to follow solution. Carried out stage 2 fix and drier is now perfect! A little patience with a dental pick to move some hard deposits but now perfectly clean. Many thanks for saving the cost of an engineer call out!

Miele WT945 drier removal


Hi dear.
It is very complicated work. I can suggest you should not involve doing that but if you know what you are doing try that out. See if it helps.
Common problem: Stuck drying air fan shaft.
1- Unplug machine from power. Remove top cover.
2- RHS at the back,on outer drum horizontally mounted motor,drives a belt.
3- Try to rotate motor shaft (impeller) by hand, see if it's hard to rotate. Try to make it free to rotate.
3- If you have a capacitance meter, check value of capacitor should be in range of 2.5 uF if not replace capacitor.
Beyond that you need to get tech. to assist your machine. I hope that helps so far. Thanks.

Miele WT945 Dryer Problems - Stage 1 fix


STAGE 1: TEMPORARY FIX TO UNSEIZE THE FAN (5 minutes)

The immediate ‘fix’ is to reset the thermal cutout (the button in the centre of the round sensor fitted on the right hand side of the long rectangular heater box atop the drum). This restores heater power, which the cutout will have tripped out due to the absence of airflow through the heater overheating it. Then, spin the fan motor (at the top rear right hand corner) back and forth by hand to free it (it will be stiff and graunchy at first but quickly frees up. Needless to say, please remember to disconnect power before attempting this tasks otherwise you are in danger of losing fingers. Once you’ve done these two tasks, put the power back on, KEEP AWAY FROM THE MOTOR and try a drying cycle. You should see the motor spin happily and the drying commence. Also beware of the heater box which will quickly get too hot to touch (don’t worry, this is normal). While this fix is easy and effective, and may well keep you in business for months at a time, unfortunately it’s not tackling the root cause, which is a steady fluff/goo buildup in the fan box itself, which impedes both airflow and the rotation of the fan. Oiling the shaft of the fan probably won’t help – the problem lies deeper in the fan box itself.

(Note that the seizure problem is nothing to do with the fan motor itself – this is perfectly OK and will spin freely if you dismount it from the unit. It’s the dryer fan that the motor is driving (through the belt) that is stiff, not the motor. So don’t waste time fiddling with your motor (unless it’s obviously bust, but this is unlikely) despite it being temptingly accessible.)

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!


Introduction

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.

See my next tip 'Stage 1 fix' to start work.

Miele WT945 leaks water from internal drain


Hi
If it is the bottom hose on the condenser box leaking.
This is a vent.
It is most likely the condenser box is blocked with fluff and will require cleaning or replacement. I imagine the appliance is not drying very well if at all

Tumble dryer blower not working


The fan gets stuck because of the build up in the condenser itself. £400 will fix it damn them. I should have bought a Candy. Am sure that there is a service mode that can flush the condenser, because it is fitted as standard on new models. The reset of the micro switch should do it and try to free off the fan manually. Miele should be more forthcoming about this, taking into account the price of the damn thing in the first place.

WT945 Dryer doesn't dry


check that the lack of air flow hasn't tripped out the thermostats. bypassing them will confirm the element hasnt blown out. but do not keep them bypassed as a "repair"
