GE Dishwasher Check Valve Piston & Nut Assembly Parts — Models & Compatibility

The check valve piston assembly in your GE dishwasher controls water flow direction during fill and drain cycles. When this small but critical component fails, you'll typically see water draining during the fill cycle, dishes coming out dirty because not enough water stays in the tub, or even water backing up where it shouldn't. The WD24X10018 is the OEM-spec replacement that fits dozens of GE, Hotpoint, and Kenmore-branded dishwashers from the GSD and GHD series.

Is This the Right Part for Your Model?

Your model number is stamped on a label inside the dishwasher door frame — open the door and look along the top or side edge. You'll see something like GSD5860G00SS or GHD5015F01AA. Cross-reference that exact number with the compatibility list below. This valve assembly replaces the older WD24X220 part number and supersedes AP2617344 and PS260690, so if you've found those numbers in old service documentation, they're the same part.

About This Replacement Part

The check valve piston sits in the pump housing and uses spring tension to open and close a seal that prevents backflow. It's made of durable plastic with a rubber seal and includes the retaining nut that secures it in place. This isn't a wear item under normal conditions, but detergent buildup, hard water deposits, or a piece of broken dish can jam the piston open, letting water drain out as fast as the inlet valve fills the tub. Some techs see this failure on machines that run several loads daily in commercial settings or homes with very hard water. The assembly installs from inside the tub — you'll access it after removing the lower spray arm and the filter screen assembly.

Installation Overview

You'll need to remove the lower dish rack, unscrew the spray arm retaining nut, lift out the spray arm, then remove the cylindrical filter assembly. The check valve piston sits in a housing at the bottom of the tub, held by a threaded nut. Turn the nut counterclockwise to remove the old assembly, clean any debris from the housing, then thread the new piston assembly into place and hand-tighten the nut. Reassemble in reverse order. Most people complete this repair in 15–20 minutes without special tools.
