replaced pressure pipe & switch hotpoint wma 32 still no

[pacst]

I have already replace the pipe - got one from diy store 44p
still no joy
I've remove the whole pressure assembly and tried the old bicycle inner tube test in a bucket of water to see if any bubbles come out - no bubbles
Haven't reassembled it yet - I can't understand what can be preventing the switch from triggering

I take it you cleaned out the pressure chamber at the tub?

Cleaned out the pressure chamber and drained all the water from the waste pipe and pump hose, made sure everything was fully sealed when I assembled it all back and now it works
Thanks for everything guys
