Samsung Ecobubble UC and dC error fixed

[ValleyMan]

Hi, I have a WW80J5555FW/EU, 2018-ish, that started having 'power loss' UC errors during washes.  Then it wouldn't start any cycles - dC 'door' error every time.  Weirdly I could get the drain pump to run by unplugging the water level sensor (at top of machine), but otherwise no activity.

So I replaced the door interlock (£10 eBay) and the control board PCB (£55 eBay) - but no change... dC... dC... dC...

On the eve of getting it taken away and replaced with a Bosch I decided to check the drain pump was functional and found its power connectors were loose, really wobbly, bearing in mind it's a 240V circuit.  So I reseated those a few times and it instantly fixed the dC 'door' error.  Unhelpful code right there!

The new PCB can stay in the machine because some components on the original one looked like they'd been hot at some point.

Hope this helps someone.
