Hi Licdan - The float/pump have been checked ok - The float is free to move and the pump microswitch is good. When closing the switch for a couple of seconds, the pump will run for about 30 secs then shut down. So I assume it is correct as the tray always seems to fill correctly
I have removed the NTCs again and checked with a multimeter:
Original Door NTC - Part 2790102/297190 01 00 - 12K - is reading 15kohm at room temp
Original Compressor NTC - Part 2790102/297190 01 00 - 12K - also reading 15kohm
Replacement NTC (Beko Spares)- Showing part 2306/2971900300 - also reading 15kohm
I assume the figures suggest the NTCs are correct? Although I'm unable to test their operating range whilst in use.
I will replace the NTCs back to their original positions and check again.
My son actually delivered the machine to a local repairers, who just switched the machine on and watched it for 15 mins, declaring no fault found. They were not prepared to let the machine run a full cycle, so didn't see it stop after 30mins
I would be grateful for any other pointers.
Cheers
Doug
