WD15X26078 Dishwasher Water Inlet Valve for GE Dishwashers

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.

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.
