it doesnt always have ot be a kink, there may simply be a bit of fluff or a block of detergent in the level pipe. unfortunately youre going to have ot get the machine out and have a proper look. if you diconnect the hoses one at a time, blow down them. dont blow from the machine end of the pipe into the pressure switch, as this may break the diaphram inside, alway blow from the switch end into the the machine. if you find nothing wring blockage wise, then then next thing to check would be the pressure switch itself. two ways to do this are either
1. obtain a wire diagram from the switch and test the continuity of the circuit.
or
2. listen very carefully to the switch while the machine is filling. when it reaches set level, there should be a small click as the diaphram operate the internal switch......this way isnt always a god method though, as the click can be very quiet.
