Beko T/D DRCS68W PCB?

Having read all other posts on a DRCS* search, I am still a bit stumped. 😥

Machine goes for about 10 secs, then stops and beeps. You can then restart it, but it stops and beeps again after 1 or 2 secs.
It does the same whether on timed or auto, with a bundle of sopping wet tea-towels in it or not.
There’s no build-up of anything around the sensor bars.
Top NTC reads the same as rear NTC and rear TOC is closed circuit.
It does the same with the heater disconnected or connected and with the drain pump connected or disconnected.
Nothing is low insulation.
Red condensor cartridge lever microswitch is operating fine.
Overfill microswitch is operating fine.
All cables have good continuity from plug to plug and there are no loose connections.

There was some low insulation on the mains cable, between live and earth, so I’ve replaced that with a good cable from an AEG donor, but the problem still persists.

I suspected the PCB, so got a replacement one (BEK2953640203), but the machine won’t start up at all with that fitted – it just sits there staring at me, with the “Clean Filter” and “Water Tank Full” lights on permanently green, along with the top two of the other four lights also on permanently green – “Drying” and “Ready to Iron”.

It’s a DRCS68W and its serial number is 06-102868-08, so the PCB should be the right one for it – also the part numbers on both pcbs match and the boards appear identical, apart from a row of resistors on one is upside down which doesn’t make the slightest bit of difference.

I still suspect the pcb, to be honest, but am hoping there’s a Beko Boffin out there that can shed some light. Pleeese. ❓

Thanks in advance,
Pigpen.
