how to fix hotpoint aquarius 800wm12?

pressure switch not switching OFF. can be a faulty switch,
a split plastic pipe from pressure switch or the pressure chamber small hole blocked with crud/powder

suggest you clear the hole out in the pressure chamber first, you will tell if this is the problem. now check the plastic pipe by blowing through it towards the switch (listen for a click switch is working ) refit try for filling
