The hotfill continues to keep running in and machine starts to flood out of the door. This means that I have to turn on the hot water tap at the back of the machine at the start of a cycle and turn it off after a few minutes, otherwise it only does a cold wash!!
Could this be a faulty hot fill valve at the back, and if so, would it be simple to replace.
Thank you.

pressure switch faulty or the pressure chamber is BLOCKED with powder residue ,even may have rubbed a hole through the plastic pipe
remove the lid locate the pressure switch ( has wires and a small plastic pipe attached) pull off the pipe and blow down if you go RED than the pipe chamber is blocked if you can blow it free this MAY cure the overfill problem
as machine fills with water the air trapped above the pressure chamber INCREASES causing the switch to turn off the water supply.
