Water Level System

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 the pressostat. When the pressostat is satisfied, it cuts the signal to the solenoid valve and sends power to the thermostats and the timer
When trouble shooting this system, all components must be considered.
Beginning with the pressostat which is adjustable.
Making sure the connection to the tube is air tight.
The tube may have an invisible crack which allows air to escape. The air trap may be broken or the threads may have a crack also.
