ZWF1640W washing machine not working

Yep, on all programs, even just drain!

At the moment I go into diagnostic mode (hold start/ turn to first option) and then "test" the water filling to get the water in the drum. Then exit and start the actual the wash - previously this didnt work, but has this morning!

So this morning I ran a white wash at 90 degrees, that worked fine - empty drum
Immediately after that I ran the spin cycle - empty drum.

Both worked fine.

Then I put a load of washing in, and ran the coloured at 40 degrees. Started draining, and then stopped, timer on 0 and door unlocked.
Put it back on spin with a load, same as the coloured wash.

Filled with water so the bottom of the drum had visible water, then started the coloured wash, still no joy.

As you will have realised by now you have a weird problem. I think your machine has a brushless motor but am not 100% sure & worn motor brushes can cause weird problems so it might be worth checking that. Other than that you mentioned removing the pcb & warm weather, did you remove & replace plugs & sockets as I am wondering if you have a bad connection from the pressure switches at the board. Other than that I can only guess it might be a fault in the wiring to the press switches or as I said earlier a faulty pcb. (not necessarily something you will be able to see by visual inspection).

The plugs were removed/reseated when i changed the pressure switches a month or so ago, and then reseated one of them lasts night, and re checked the other at the same time.

The connectors to the pcb were removed and refitted also as i removed the PCB.

I guess one more opening and checking the wiring loom, connections and brushes. There is a service i found on ebay who test and repair the pcb's for approx £40 so may have to look at that option!

The heating element is working as the 90 degree wash resulted in a warm bowl, but will double check those connections too!
