Re: Siemens XL 1600 not heating water

Thanks Mr P. The board is pretty expensive to replace but I’ll take it out and check for anything obvious before I make a decision. At the moment, I’m running hot water via funnel and hose into the soap dispenser but this isn’t exactly ideal :rolls:

Re: Siemens Tumble dryer not heating

Oh well, it’s done sterling service over the years – all those baby clothes that it shrunk, not to mention the waistline of my trousers – odd that.

I might just check for any dry joints before I give up altogether – a new pcb is just too expensive to be worth replacing at this stage.

Thanks for your help.

Re: Siemens Tumble dryer not heating

Finally had time to take some more bits off this blasted thing and got at another thermistor at the front of the machine. This one reads 12.5kohm at room temp and drops when heated with the hair dryer. If all the thermistors and the thermal cut-out are OK, and the elements appear to be unbroken, what is left to go wrong? Could the pcb be faulty and if so is there anyway of checking before I consign this to the scrap heap?

Any more suggestions (polite ones please) gratefully received.

Re: Siemens Tumble dryer not heating

Thanks helo_75, but it really won’t push in! Anyway, I don’t think that is the problem – it is not open circuit as far as I can tell – it measures zero ohms. I wish it had been that though – I was hoping for something simple and obvious but just my luck to get a tricky one :rolls: !

Re: Siemens Tumble dryer not heating

The red thing doesn’t appear to move so I assumed it hadn’t tripped (if that is what it is supposed to do) but maybe it is a single-shot type. It was not clear to me whether it should normally be closed (zero resistance) which is what it is now, or open.

The elements are actually slightly different physically – one of them is about twice the diameter of the other – if you think of the coil as a tube of coins, one is 1p pieces, the other 5p, if that makes any sense 😆

For something that should be really simple, these things are complicated – the devil is definitely in the detail.
