Thanks for reply, I have removed valve it was not stuck and coil is ok. I can see what it is supposed to do but by operating it out of the washer i do not see how it does it. The flap just does not get pushed out by the vibrating solenoid. I have looked for spare on Connections and it is shown as part of the circulation pump only. Qualtex don’t list it.
Any other help on this one would be welcome. Thanks Brian.
