HOTPOINT WASHER OVERFLOWS ON ALL CYCLES

Hi,
This is most likely a damaged pipe going to the low pressure sensor. This sensor determines when to turn water off by the pressure built up in a tube. If there is a damaged pipe - it wil overflow.

Turn off and disconnect machine, then remove access pannel to inspect all small bore pipes for damage. Check pressure valve for correct operation.

If it leaks at times other than filling, and water level seems ok, then it could be a damaged top or bottom seal that needs identifying and replacing.
If it leaks constantly it could equally be a damaged rubber pipe between drum and pump.
You really need to remove an access pannel - and just observe operation without putting your fingers in thereto spot it.
