What the air break does in a Westinghouse dishwasher

Incoming water passes through the air break on its way into the tub. Its built-in air gap stops dirty water from being drawn back into the household supply, and the flowmeter counts how much water comes in so the control can fill to the right level. When this assembly cracks or its flowmeter fails, you may see water leaking down the side of the cabinet, a machine that overfills or underfills, a cycle that stalls at the start, or a fill error.

Before you fit the air break

Turn the dishwasher off at the wall and close the water tap. Check the serial number on the rating label against your model before you start. The air break usually sits on the side of the tub, behind the side panel, so the dishwasher may need to come out of its cavity. Note every hose and wire connection, transfer them across, then run a fill and watch for leaks.

Questions about this part

Why does the serial number matter?

Fit for this air break is tied to the dishwasher's serial number, so two machines with the same model number can need different parts. Send us the model and serial number from the rating label on the door edge and we'll confirm the right one.
