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?

The wiring sounds wrong somewhere. The water level sensor has two switches
inside which will turn on / off at the set water level. The first, shallow,
level is working OK, but the second, deeper, level isn't working.

Check that the diaphragm switch isn't faulty first by blowing up the tube
from the bottom. Blowing gently should activate the first switch. Blowing
a bit harder should activate the second switch. You should hear them both
operate as you blow.

Check the switch on the timer unit to make sure it's working OK. Putting a
meter or a lamp over the switch and operating it will tell you if it is
fine.

Check your rewire. Make sure you have the water level diaphragm switches on
the correct parts of the timer unit.
