The latest news: changed the pressure switch, cleaned the contacts oin the ciurcuit boards. Also pulled out the turbine and cleaned it – full of gunk.
Now this:

So for the first time the symptoms have changed which makes me feel happier. Is this now a water leak?
(Also – what colour are the wires that go into the float switch – blue or orange? I fear I may have mixed them up with the pressure switch – same connector, same lead length, stupid error on my part)

1 remove and reconnect the wires to the pcb in case of bad joint

2 let it fill up and the switch off at plug with water in and see if pressure sw has operated

OK – will check that – good idea!

Edited the above post to include latest information… still stuck.

Right – thanks for the idea but it didn’t work:

• I removed the pressure switch and tested it by blowing into it, and measuring the electrical resistance. The switch closed when the pressure was applied.
• I also checked the pipe, which was intact – and I blew through it – it was clear.

So, perhaps the pressure switch is out of calibration? Likely, or not? Is this how pressure switches fail?

The operation of the cycle also may provide a clue:

• The machine drains
• The machine fills
• At the end of the fill, there’s a clunk and for a fraction of a second the main turbine seems to spin – can hear the characteristic “whoosh” – but then everything stops and the lights flash.

Any ideas?

Thank you – will check that.
