Indesit filling and pumping at same time

[Chrisyorks1961]

I have a WIXE167 which fills and empties constantly thn gives error H20 (lack of water) as it is empty!!
Checked pressure switch, connections on main board, tested thermistor, and ran pump fully on emptying cycle until it stops. I suspect main module, but all else seems fine.

Thanks for reading.

Thanks anyway

Have you Blown down the Presure pipe to see if it's clear.

I have had the pipe off at the pressure switch end, but not blown it through yet. Something to try...thanks.
