How to Install a Pressure Tower in a Dishwasher

Water is dispensed during the cleaning cycle in a dishwasher by means of a pressure tower, which is also commonly called a spray arm. The pressure tower is located inside the dishwasher at bottom center of the appliance; the tower also features a plastic blade
that spins during the cleaning cycle. If water is not dispensing through the pressure tower, you can remove the current tower part and install a new one. New pressure towers can be purchased and ordered from the dishwasher manufacturer or an online retailer.
