Indesit XWA 71451WUK washer won't stop Filling
I’ve a problem with my Indesit XWA 71451WUK washing machine after moving house. It constantly feeds water through the Wash detergent compartment into drum at full rate throughout every stage of every cycle including Spin. Drain system set-up is correct (no siphon), as is water feed pressure. No debris in water valves or filters. Both water valve solenoid coils have continuity and correct resistance, and both valves shut off water completely on operation of either Pause or Power Off buttons, or when mains power is switched off. Pressure switch seems ok as drain pump kicks in as soon as drum water level exceeds max operating level and runs until correct waterlevel is restored, when pump stops. Pressure pipe blows through into drum ok. No error codes are shown. Any advice?

If the water only stops when the machine is paused, switched off, or isolated from the mains, that points away from a plumbing/siphoning issue and towards the valve being energised when it should not be. After a house move, the most likely causes are a wiring/connector fault, a pressure sensing issue under load, or a control board fault.
Before checking anything internal, isolate the appliance from the mains.
1. Confirm exactly which compartment is being fed You say it comes through the wash detergent section. That matters because each inlet valve outlet is usually controlled separately. If it is always the same section filling, that helps identify which valve circuit is being held on.
2. Check the dispenser-to-valve wiring and plugs Remove the lid and inspect the inlet valve connectors and loom back towards the control board. Look for a loose plug, trapped wire from the move, rubbing damage, or signs of moisture/corrosion. A misconnected plug can cause odd filling behaviour.
3. Recheck the pressure system carefully Even if the pressure switch reacts at high level, it may still be giving false/late level information during the cycle. Check the pressure chamber on the tub for gunge restriction, not just the hose. A partially blocked chamber can make the machine overfill or keep calling for water.
4. Test whether the valve is being permanently powered If you have the skill and safe test equipment, measure whether the affected solenoid is getting 230V during stages when it should not be filling, such as spin. If it is, the control system is commanding it on. If it is not, yet water still flows, the valve is mechanically sticking under live conditions despite resistance readings.
5. Likely suspect: main control board Because the valve shuts properly when power is removed, a stuck relay or triac on the PCB is a strong possibility. This is quite common compared with a pressure switch failure that behaves exactly as you describe.
At this point I’d be leaning towards a control board or pressure chamber issue rather than the valve itself. If you’re not confident with live electrical checks, it would be best to get a qualified appliance engineer in, especially for any mains-related diagnosis.

SAFETY FIRST: READ BEFORE ACTING ON THIS GUIDANCE
Never work on a live appliance
Always unplug it at the mains before going near it with any tools.
Never attempt gas work
By law, gas appliances must only be worked on by a Gas Safe registered engineer. If your fault involves gas, stop and call a professional. Do not attempt it yourself.
Watch for sharp edges
Outer panels are smooth, but internal parts have sharp machined edges. Wear protective gloves and arm sleeves.
Water appliances can leak
Turn off the water supply before disconnecting any hoses.
Know your limits
If you are not confident testing or working inside the appliance, stop and call a professional.
