Zanussi ZWF1437 Error code 31, lights but no response?

Hi

I hope I can get some expert advice.

Zanussi-Electrolux ZWF1437, lights are on but no response.

Error code is E31. Three beeps emitted.
Bit more background - came back after some time away to cold damp house. Put washing in, worked but did not drain. Drained manually and there was some debris in filter. All clean but no response from machine apart from blinking lights at me.
Pressed start and skip buttons together (trial and error - did not know this was the way to do it) and got E31 followed by three beeps.

Let it rest for two days. Worked (as opposed to lights but no action) but clothes were wet when I went to empty.

Now back to square one, lights but no action.

(Drain filter and pump clean - already checked)

Advice and help will be gratefully received.

Check the pressure switches and pipes leading to them,

turn off the power
remove the lid
remove the pipes on the pressure switches and blow into the pressure switches (should hear several clicks) and the pipes (should blow clear into the drum)
Occasionally the pipes get holed especaily near the pressure chamber end.

E30 faults are commonly associated with pressure system faults.

Thanks very much for taking the time to reply.

I've already tried that but no difference. What else can I try.

Thanks again.

Just wanted to post an update to help those suffering similar problem.

Replaced analogic pressure switch and the machine works.
