Machine won't switch on

Before you replace the valve, try to back flush it. It may allow you to run water through it from both directions and clear the obstruction. That wil save you the cost of a new valve. Also, get some inlet hose filter screens. They go into the supply hoses, with the narrow pointed end toward the water supply.

Hi from retired Englishman in SW France,

Sorry but with such a fault it is virtually impossible for anybody on this forum to remotely guess what is wrong with your washer.
It could be internal wiring/plugs sockets, control panel switches, control PCB, water inlet control valves, door solenoid, main motor, drain motor etc..
I fear that your only real option is a service call as the engineer will have the right equipment to safely diagnose what is wrong.

If this has assisted you please consider a 4 thumbs up for the rating.
Thanks and good luck!
