XPARTCO WH16X29509 Washer Damper Vent
The XPARTCO WH16X29509 is an aftermarket replacement washer damper vent compatible with select GE, Hotpoint, RCA, and Kenmore front-load washers in the GFW510, GFW550, and GFW650 series. The damper vent is a one-way flap valve located on the drain system that automatically opens during draining to equalize pressure inside the drain pipe, allowing water to drain quickly and completely. When closed, it seals the drain path to prevent backflow of residual dirty water and lint from re-entering the drum and soiling clean laundry.
Made from high-strength plastic with a reinforced hinge mechanism, this damper vent is designed to resist deformation under high-frequency operation and to prevent lint accumulation that can cause blockages. It directly replaces OEM part numbers WH16X29509, 4982970, AP6990392, and several additional cross-reference numbers. Snap-in installation requires no special tools and takes just minutes to complete.

Installation Notes
⚠️ Unplug Washer Before Starting Unplug the washer from the power outlet before beginning any repair. The damper vent is located in the drain system — typically accessible from the front lower panel or by removing the washer's access panel. Locate the existing damper vent on the drain hose or drain port. Press the tabs or release clips to remove the old damper vent from its snap-in mounting position. Align the new WH16X29509 damper vent with the mounting port and press firmly until it snaps into place. Restore power and run a short drain or rinse cycle to verify the washer drains correctly and no error codes are displayed. Tools needed: None for the damper vent itself; a screwdriver may be needed to remove the access panel on some models.
Frequently Asked Questions
What does the washer damper vent do?
The damper vent is a one-way valve on the washer's drain system. During the drain cycle, it opens automatically to equalize the air pressure inside the drain hose, which allows water to drain quickly and completely. When draining stops, the flap closes to create a seal that prevents residual wastewater and lint from flowing back up the drain hose and into the drum — which would re-soil clothes that have already been washed.
What error codes does a failed damper vent cause on GE washers?
A blocked, stuck, or failed WH16X29509 damper vent is a known cause of error codes 38, 39, 40, and 84 on compatible GE GFW510, GFW550, and GFW650 series front-load washers. These codes are typically triggered when the control board detects a drain pressure or flow issue. Replacing the damper vent resolves the issue in many cases when the drain pump and hose are otherwise clear.
How do I know if my damper vent has failed?
Common signs of a failed damper vent include slow or incomplete draining, one of the error codes listed above, dirty water or lint reappearing on clothes after a wash cycle, or a stuck flap that is visibly open or closed when it should not be. You can inspect the damper vent by removing the access panel and checking whether the flap moves freely — it should open easily when you apply gentle pressure and spring closed when released.
Is the WH16X29509 compatible with GE Profile and GE Café washers?
The WH16X29509 is confirmed compatible with select GFW and PFW series models from GE and GE Profile. GE Café washers use different model series — verify your specific model number before ordering. Contact our support team if you need help confirming compatibility for your Café or Profile model.
Is this an OEM or aftermarket part?
This is an aftermarket replacement part built to OEM-equivalent quality standards. It is not a genuine GE OEM part, but is manufactured from high-strength plastic to match the dimensions and performance of the original WH16X29509 damper vent.
