Siemens Wd12D520 Stops Drying
Hello
My washer dryer stops after ten mins or so into a dying cycle... this happened before under warranty and a helpful chap came and unclogged something inside that was full of fluff, the condenser chamber perhaps?
Looks like I need to do this again, can anyone offer advice as to what I'm looking for? I had a look earlier today but couldn't see anything obvious!
Thanks in advance,
Ant

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Siemens Wd12D520 dryer cycle stops after about 10 minutes
- The problem
- A Siemens Wd12D520 washer dryer was stopping roughly 10 minutes into a drying cycle. The owner noted that a previous warranty repair had involved clearing fluff from an internal area, possibly the condenser chamber, and suspected a similar issue again.
- Likely cause
- The strongest supported diagnosis is a blockage in the condenser chamber area or the hose from the bottom of that chamber to the tub, preventing condensate from draining or steam from condensing properly. Other possible causes mentioned were failed fan operation, heater failure, or an open thermal cut-out/thermostat, but these were not confirmed.
- What fixed it
- Recommended action was to check whether the machine heats during drying and whether the fan runs, then inspect the plastic condenser chamber at the back of the machine and the hose from its bottom for blockage. No completed repair or confirmed fix was reported by the owner.
- Checks to try
- Whether the dryer gets hot during the drying cycle
- Whether the fan is running
- Plastic condenser chamber at the back of the machine
- Hose from the bottom of the condenser chamber to the bottom of the tub for blockage
Safety: Do not touch the machine while connected to the mains. Further diagnosis should be carried out by a suitably qualified appliance engineer.

Sorry Ant, it's not forced to be the same cause although it may be and I can understand why you'd assume it was. I try to give general repair advice rather than strip down instructions but I'm not familiar with your model anyway. I can explain how it works so if you can work out what to check from that it will be a help, if not you'd be better not taking things to bits to be honest.
The dryer on a washer dryer is a condenser dryer so water should trickle into a condenser chamber when the steam from drying the laundry is blown as well. The steam hits the trickle of cold water and condenses back into water where it gets pumped down the drain.
If the condenser chamber gets blocked at the bottom it can stop the condensed water running into the pump. If the water stops running into the chamber the steam won't condense and also cause a fault. Likewise if the fan stops running it won't pump the hot air into the chamber and of course if the heater stops working it wont dry them either. Then there are stats and thermal overload cutouts which can go open circuit and stop the heater from working.
Don't touch the machine with it connected to the mains, some of these wires can be live even when the machine is not running.
If it gets hot on dryer and the fan is running then the fault may well be to do with the condenser chamber. Check for the plastic condenser chamber at the back of the machine and make sure there isn't a blockage in the hose leading from the bottom to the bottom of the tub.

Thanks very much for the comprehensive reply, Andy!
I'll have another go, hopefully at the weekend!
