I bought one use was light domestic then after a while it started to spray water out from the inside ,,switched it off
it was still under guarantee with a year to go but i needed it for the job ,so i took the cases off and found it had a plastic cylinder head ,the leak came from the water pressure switch housing ,as this is a unit moulding i had to cut the housing in half ,then i saw the crack as its a low pressure side of things i decided to repair it with a high pressure adheasive and 2 screws .

the crack in the housing was caused by vibration,and on inspecting the outlet port i found another sign of a crack,
things did not look any better when i examined the switch
the conectors had no insulation what so ever and when it was assembled a negertive wire was pinched and there was a bare wire ,and the distance between the terminals
was about as much as a fag paper ,the washer works now but i have no pressure switch ,
DONT ATTEMPT THIS REPAIR YOUR SELF IF YOU GRT THI PROLEM SEND IT BACK !
