WD15X26078 Genuine OEM GE Dishwasher Water Inlet Valve
The WD15X26078 is a Genuine OEM GE replacement dishwasher water inlet valve compatible with a wide range of GE, GE Profile, Café, Haier, Hotpoint, RCA, and Kenmore GE-built dishwashers. The water inlet valve is mounted at the base of the dishwasher behind the lower access panel, connecting the household water supply line to the dishwasher's fill circuit. When the control board calls for water during the fill phase, the valve's internal solenoid opens, allowing water to flow into the tub — and it closes the instant the call is dropped, stopping flow precisely at the correct fill level. Without a properly functioning inlet valve, the dishwasher can't fill correctly — leading to poor cleaning performance, error codes, or no wash at all.
Rated 120V, 60Hz. Approximate dimensions: 3.75" H x 3.25" W x 3.00" L. Silver/multi-color metal and plastic construction with a deep-threaded, high-quality water inlet for a tight supply-line connection and a secure outlet design that keeps the internal fill hose firmly attached. As a Genuine OEM part manufactured by GE to factory specifications, the WD15X26078 directly replaces 4959029, AP6986683, PS16217027, EAP16217027, and PD00064270. Hard water sediment is a leading cause of inlet valve clogging and failure on GE dishwashers — if your old valve is restricted by mineral buildup, replacement (not cleaning) is the recommended fix, as the internal components are easily damaged during cleaning attempts. Installs in 20–30 minutes with basic hand tools.

Installation Notes
⚠️ Unplug Dishwasher and Shut Off Water Supply Before Starting — Wear Work Gloves Disconnect power at the breaker and shut off the household water supply at the shutoff valve under the sink before beginning. Wear work gloves to protect your hands. Have towels and a shallow dish ready — residual water remains in the supply line and hoses and will spill when disconnected. Remove the lower access panel (baffle) at the front bottom of the dishwasher — typically 2–4 screws. Locate the water inlet valve where the household supply line enters the dishwasher. Photograph the hose and wire connections before disconnecting anything. Disconnect the household water supply line from the valve inlet (use pliers for the larger ingress connection — place the dish underneath to catch leftover water). Disconnect the internal fill hose from the valve outlet (needle-nose pliers help with the smaller egress hose clamp). Unplug the electrical connector that snaps onto the valve solenoid. Remove the mounting screws holding the valve bracket to the frame and lift the old valve out. Install the new WD15X26078 valve in the same position, secure the mounting screws, reconnect the internal fill hose with its clamp, and snap the electrical connector back on. Reconnect the household water supply line to the valve inlet — align the threads carefully and tighten snugly without over-torquing. Turn the water supply back on and use a flashlight to inspect all connections for leaks BEFORE reinstalling the access panel. Restore power and run a test cycle to confirm proper filling with no leaks. Tools needed: Phillips screwdriver, pliers, needle-nose pliers, shallow dish, towels, flashlight, work gloves.
Frequently Asked Questions
What does the H2O error code mean on my GE dishwasher?
The H2O error code on GE dishwashers indicates the control board is not detecting sufficient water intake during the fill phase. Common causes are: a failed or clogged water inlet valve (the most frequent culprit), the household water supply shutoff valve partially closed, a kinked supply line, or low household water pressure. First verify the supply valve under the sink is fully open and the line isn't kinked. If the supply checks out, the WD15X26078 inlet valve is the standard fix — hard water sediment gradually clogs the valve's internal screen and passages, restricting flow until the dishwasher can't fill within its expected time window.
Can I clean the old valve instead of replacing it?
It's not recommended. While the inlet screen on some valves can be carefully brushed clean, the internal passages and solenoid diaphragm of a sediment-clogged valve are easily damaged during cleaning attempts — a common outcome is a valve that leaks or sticks open after being "cleaned," which risks flooding. Real-world experience (including customer stories with this exact part) shows that attempting to clean a hard-water-clogged valve often breaks it. Given the moderate cost of the OEM replacement versus the flood risk of a compromised valve, replacement is the reliable repair. If your area has hard water, consider this a maintenance item that may need periodic replacement.
My dishwasher won't stop filling — is that also this valve?
Yes — a valve stuck in the open position is the other failure mode. When sediment or a worn diaphragm prevents the valve from sealing fully closed, water continues to flow into the tub even when the control board has cut power to the solenoid. This can lead to overfilling and potentially flooding through the door or float overflow. If your dishwasher keeps filling past its normal level, or you find water accumulating in the tub between cycles, shut off the water supply at the sink immediately and replace the valve before running the dishwasher again.
How do I know this is the right valve for my GE dishwasher?
Check your dishwasher's model number (on a label along the door frame or tub edge) against the compatibility list above — the WD15X26078 covers a broad range of GE GDF, GDT, GDP, Profile PDT/PDP, QDP, Monogram ZDT, DDT, and Café CDT series dishwashers. Be aware that some similar-looking GE valves (such as WD15X24213 or WD15X26140) are different parts used on other model groups — they are not interchangeable with the WD15X26078. If your model isn't in the list or your original valve shows a different part number, contact our support team with your model number and we'll verify the correct valve before you order.
Is this a Genuine OEM or aftermarket part?
This is a Genuine OEM part manufactured by GE to factory specifications. It is the exact same water inlet valve installed in compatible GE, GE Profile, Café, Monogram, Haier, Hotpoint, RCA, and Kenmore GE-built dishwashers from the factory — guaranteed fit, materials, and performance.
