Your question has come across to the UK appliance category.
When the appliance stops mid cycle, is it empty of water?
Do you hear a hum or buzz from the bottom rear?
Thanks for that.
Unplug the appliance and take the left side panel off.
Check for blockages in the metering tank (large tank on the side) and in the hoses to/from it.
Clean it all out and try the machine again.
There is a small hose going to the top of the inlet valve.
Water is spilling over, going into this hose and locking the valve.
You could turn the water supply valve right down so water comes in much slower to see if it will work. If it does, you have restrictions causing back pressure.
If it still locks out, you have a near blockage.
Hope this is of some help
Let me know how it goes or if you need more help
Yes, the material is the water softening unit.
That should be there.
Let me know how it goes when you try the machine out.
Good luck with it.
It got worse when I started the machine, but I discovered that this was my own fault as I has not reconnected the pressure switch pipe. Now perfect.
Thanks for letting me know how it went.
Glad you got the machine working again.
Thank you for the payment, it is appreciated.
Good luck with the appliance.
