Siemens Tumble Dryer switching itself off

[tiddlywinks]

Hello all
My Siemens Tumble Dryer WT46W566GB keeps switching itself off after about 5-30 seconds despite washing being very damp. Can anyone shed any light on why this might be happening please? Thanks in advance

Does it show any sort of fault code?

 

[tiddlywinks]

No, just stops.

No, just stops.

Stops with, or without, any lights lit?

 

[tiddlywinks]

The light goes off and it stops 5-30 secs after being switched on, the way it used to at the end of a normal cycle.

Can you switch it straight back on again? Have you tried plugging it into a differnt socket? Does the display light up with the door open before you actually set it going? If you hold the start button pressed does it continue to work until you release it?

Its probably got itself in a spin.

That seems to be instant off of motor and controls/display. A normal shutdown sequence usually keep the drum rotating, to cool clothes down, after drying. I would guess at it loosing its supply, via a bad connection (see jj4091's post above), either at the plug, or within the machine itself.

Hello again, sorry, have been away. Checked the fuse and plug, machine now completely dead, not coming on at all. So I guess it's a power fault within the machine, presumably I'll need an engineer? Thanks again.

Just called Siemens and they say the control module is over £400 before vat and labour recommend a new machine. Shame about the planet.

OK - Another possibility, if you suspect the PCB...

Can you remove the PCB, and inspect it closely? Use a lens. Look at the electrolytic capacitors, check everyone one for bulges, swelling, or electrolyte escaping at the wire terminals, or the rubber bung being pushed out. Sometimes, you might see the alloy tops, doming a little. Any which are failing need replacing, they cost just a few pence each, with the correct value, which is marked on the side.

Electrolytics, are encased in an alloy case, with a coloured plastic outer. The colour is most often pale blue, but can be dark blue, yellow, or black, and have two wires, sealed by a rubber bung. Polarity is important, it will be marked on the plastic.

Thank you so much for taking the time to explain this. Will consult my friend who understands electronics.
