Water Level System 1 888 275 4538 - 611 514 737 9701 - 611 The dishwasher water level is control by a pressure switch or pressostat. A cup (grey plastic cylinder, #10528) located at the back of the unit will keep an air pocket which will be pressurized as the water level increases. The air pressure (approximately 2 inch water column) activates a switch through a rubber tube that connects from the air trap to the pressostat. During the fill cycle, the water solenoid gets its signal from th

Fill System & Rinse System The dishwasher fill and rinse systems is practically the same system as they both used the same circuit. The only difference is what is sending the signal to the water solenoid valve. During the fill cycle, the water solenoid gets its signal from the pressostat. When the pressostat is satisfied, it cuts the signal to the solenoid valve and sends power to the thermostats and the timer. During the Rinse cycle, the water solenoid valve is getting its signal from the
