This assembly controls the flow of water to the spray arms, directing wash water to the upper or lower spray arm at the correct point in the cycle for thorough, even cleaning.\u003c\/p\u003e\n\u003cp\u003eThe assembly includes a valve and float mechanism designed to optimize water flow while minimizing noise. Common causes of failure include a worn or cracked diverter valve, or a rubber boot\/hose connection that develops a leak over time. Symptoms of a failing diverter assembly include water pooling underneath the dishwasher, poor washing performance from one or both spray arms, or unusual noise during the wash cycle. It directly replaces AP6871922, WD18X21678, 4922277, PS12710077, WD00X25260, WD19X25259, and WD19X25278-25PK.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pom-qa\"\u003e\n\u003cp class=\"pom-qa-label\"\u003eQuick Answer\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eXPARTCO WD19X25278 Dishwasher Diverter Assembly\u003c\/strong\u003e fixes GE, Hotpoint, Haier, Monogram, and Café dishwashers with water pooling underneath the unit, poor washing performance from the spray arms, or unusual noise during the cycle.

Wear work gloves. Open the dishwasher door and remove the racks to expose the bottom of the dishwasher.

Reconnect any hose connections and reinstall the dish racks. Restore the water supply and power, then run a test cycle — ideally checking underneath the unit partway through — to confirm no leaking from the diverter area and correct water distribution to both spray arms.

If the diverter's rubber boot or hose connection has developed a leak, water can spray or drip during the wash cycle and collect underneath the unit. One customer traced their leak to a factory-defective hose in the diverter assembly, and unfortunately the leaking water had also gotten into their circulation pump motor over several loads, eroding the motor brushes — so it's worth inspecting the pump motor as well if you've had a diverter leak for a while before noticing it.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pom-faq-item\"\u003e\n\u003cp class=\"pom-faq-q\"\u003eAny tips to avoid damaging the new part during installation?\u003c\/p\u003e\n\u003cp class=\"pom-faq-a\"\u003eYes — make sure the new diverter is fully engaged with the spout on the wash pump before tightening the hose clamp. One customer's first replacement part was ruined because the clamp was tightened before the assembly was properly seated, which cut into the tube.
