Siemans condenser dryer WT46W567GB/16 – No heat

[asp11]

This runs fine but just doesn’t heat

It is a machine that I’ve never worked on before, it has some sort of compressor thing instead of a traditional heater I believe, because I didn’t find an actual heater inside it???

Looked around for any reset buttons or broken wires but everything appears in order.

Any ideas or do I need to leave it to a Siemans engineer ❓

it uses waste heat and recycled heat from the compressor to dry the clothes

one thing to note is the heat is a lot lower than a standard tumble dryer and with the compressor unit it forms a de-humidifier

i have no info on Siemens but will pm you a similar zanussi one. i realize its different but the op principles are the same

That’s great, any help on this will be amazing.

You say “it uses waste heat” but where does the heat come from in the first place? I saw no obvious element in the back panel area or inside, this confuses me. So it must have a load in it to heat (I tried it empty expecting to feel warmth straight away) It was on for about 5mins and I felt nothing warm at all but I did hear a pump/compressor noise. No error code though it just bleeped and stopped

the compressor produces heat because its a motor after that the unit act like a fridge ( heat pump) cools first to drop water and adds the heat back and recycles it

look at the zan manual it may explain it better but it does not get that warm its not meant to

It beeped and stopped probably because it sensed there was no wet load in the drum. Its quite difficult to diagnose ‘no heat’ faults on these appliances. They do take longer to dry on the sensor programmes ( can be 4hrs + on a full towel load) and as you’ve seen , the heat produced is much lower than usual. Because of their design , they don’t like cold outdoor type locations (sheds/garages etc) especially when temps start to fall. What was the actual complaint?
