WD15X26078 Dishwasher Water Inlet Valve

Key Features

  • Precision Water Regulation: Calibrated to provide the specific water volume required for GE's high-efficiency wash cycles, ensuring the tub reaches the correct level for the spray arms to function.
  • Quiet-Flow Solenoid: Engineered to reduce "water hammer" noise and vibration when the valve opens and closes throughout the cycle.
  • High-Temperature Polymer: The valve body is constructed from heat-stabilized, food-grade plastic to withstand the high-temperature incoming water used during sanitize modes.
  • Stainless Steel Mesh Filter: Includes an integrated internal screen to catch sediment and pipe scale before it can enter the dishwasher's internal components.

Compatibility & Fitment

This water inlet valve is designed for a wide range of modern GE built-in dishwashers. Key compatible models include:

  • GDF Series: GDF630PGM4WW, GDF530PGM4BB, GDF630PMM4ES, GDF530PSM4SS, GDF630PSM4SS.
  • GDT Series: GDT630PGM4WW, GDT630PSM4SS, GDT630PMM4ES.
  • GDP Series: GDP630PMM4ES, GDP630PYM4FS.
  • Other Brands: Compatible with select Hotpoint and Haier dishwashers utilizing the WD15X26078 part specification.

When to Replace

  • Dishwasher Not Filling: The cycle starts and the drain pump runs, but no water enters the tub, often resulting in a humming sound followed by the machine timing out.
  • Persistent Leaking: Water trickles into the dishwasher while it is not in use, which can lead to overfilling or triggering the flood float switch.
  • Poor Cleaning: Low water levels prevent the pump from generating enough pressure for the spray arms, leaving dishes dirty or covered in soap residue.
  • Incomplete Cycles: The dishwasher stops mid-cycle because it failed to fill within the allotted time (Timeout Error).
  • Loud Buzzing: The electromagnetic solenoid is failing or stuck, creating a loud vibration during the fill phase.

Installation Tips

  • Safety First: Shut off the electrical power at the circuit breaker and turn off the water supply line under the sink before starting.
  • Accessing the Valve: This part is located behind the bottom kickplate (toe kick) on the lower-left or lower-right side of the dishwasher frame.
  • Hose Connection: GE valves typically use a 3/4" GHT (Garden Hose Thread) intake. Ensure the brass elbow fitting from your old valve is cleaned and reinstalled with thread seal tape on the brass-to-brass threads only.
  • Electrical Plug: Securely snap the wiring harness onto the solenoid terminals. It is a keyed connector that should only fit in one direction.
  • Leak Test: After connecting the water line, turn the water back on and check for drips at the fitting before reattaching the kickplate and turning the power back on.

This valve is identified by part number WD15X26078 and replaces or cross-references with 4959029, AP6986683, PS16217027, EAP16217027, and PD00064270.
The water inlet valve regulates the flow of household water into the dishwasher. It opens during the fill portion of the cycle so the machine receives the correct amount of water for washing. If the valve does not open properly, the dishwasher may underfill and clean poorly. If it does not close properly, it can contribute to leaking or unwanted water entering the tub.
Typical symptoms include the dishwasher not filling or filling too slowly, dishes coming out dirty because of low water level, unusual buzzing or humming during the fill cycle, fill errors, or water leaking around the valve area. Before replacing the valve, check that the house water supply is turned on, the inlet line is not kinked, and the inlet screen is not clogged with sediment.
For many dishwashers, this is a moderate repair. Basic steps are to disconnect power, shut off the water supply, access the lower front or underside of the dishwasher, disconnect the water line and wire connector from the old valve, remove the mounting screws, then install the replacement valve and reconnect everything. Common tools may include a screwdriver, adjustable wrench, and pliers. On many models, the job can take about 30 to 60 minutes.
Unplug the dishwasher or switch off the breaker, and turn off the water supply first. It is also a good idea to inspect the inlet hose for damage, check for mineral buildup or debris in the water line, and verify the electrical connector is clean and secure. After installation, turn the water back on and check carefully for leaks before running a full cycle.
Common causes include sediment or hard-water scale restricting the valve, normal solenoid wear over time, and damage from water supply issues or repeated cycling. If your home has heavy mineral content in the water, checking the supply line and screen for buildup can help prevent repeat fill problems.
