karcher pressure washer 432m super?

disconnect pressure valve clip to release the plastic housing check the micro switch for continuity with multimeter if this is ok undo pressure valve by using a socket to turn it anticlockwise this should now pull out check seals are ok then inside the hole which the valve as just came out pull out the little float get a parts diagram off the net it is position 9. on this there is a little o ring the float should move up and down when pressed with your finger the o ring on my washer had came off and had jammed the float put the same seal back on to the float assembled back together and worked a treat no need to buy a new one now.
