Colston 700S countertop dishwasher, made in Sweden c. 15 years old,
sticking on rinse cycle. I dismantled the programmer and cleaned
the contacts and re-assembled. Now it's not turning off the second
solenoid tap which fills for the main wash cycle, so it floods. The
diaphragm water-level sensing switch works ok for the first solenoid
tap on the pre-wash, so its not that. The programmer is a series of cam
operated rocker switches. The first rocks one way to fill for the
pre-wash and the other way for the main wash. All connections are
making ok. Any idea what could be going wrong?
