Old solenoid was open circuit/burned out. Dishwasher does not cycle properly now - with the pressure pipe connected to the diaphragm assembly, but works fine with the pipe disconnected. There is clearly enough pressure in the pipe, at certain times in the cycle, to activate the very sensitive rubber diaphragm, block water flow, and bring the cycle to a standstill. Are there differing sensitivity/stiffnesses of diaphragm available or............. is there some kind of reset process required after replacement of assembly such that the aquastop assembly only activates when it should - rather than immediately it senses the slightest positive pressure? Thanks
