He says "Some newer GE dishwashers have a separate drain pump and motor; the older models, however, used a drain solenoid valve (item 1 in the above thumbnail). If this solenoid fails, the dishwasher won’t drain, plain and simple. If the solenoid cannot pull in the silver plunger, the drain port will not open to allow the motor and pump assembly to drain the water out. Use your ohm meter to test the continuity of the solenoid coil. You should also test to see if it’s receiving 120vac when the dishwasher is supposed to be draining.
