6000 & 7000 Series DISHWASHERS
The following points are listed in relation to the Pressure
Switch function and operation.
• The Pressure Switch Level 1 is set at a level lower than the
level required for the timed water fill. This is to ensure that
water enters the dishwasher before the controller activates
the heater circuit.
• Contacts P1-11 to P1-12 provide an open circuit signal to
the controller when the Level 1 water level is satisfied.
• At the satisfied position the controller senses the open
circuit neutral circuit and advances the program.
• The actual "head" of water present in the bottom of the Tub
actuates the Pressure Switch Diaphragm, resulting in a
satisfied condition.
