WW01F01651 Washer Quad Water Valve Assembly – The essential fix for a GE front-load washer that won't fill with water, fills extremely slowly, won't stop filling (overflow risk), fills with the wrong temperature water, has a bleach or fabric softener dispenser that won't fill, or leaks water from the rear valve connection. The water inlet valve is the gateway between your home's water supply and the washing machine — it's the electrically controlled valve at the rear of the washer where the hot and cold supply hoses connect. This quad (4-solenoid) valve assembly provides precise water control for four separate functions: hot water fill, cold water fill, bleach dispenser fill, and fabric softener dispenser fill. The control board energizes the appropriate solenoid for each phase of the wash cycle, opening an internal gate to allow water flow. When a solenoid burns out electrically, the corresponding water function stops completely — no hot water, no cold water, or no water to the dispensers. When a solenoid sticks open mechanically, water flows continuously even when it shouldn't — creating an overflow risk. Mineral buildup from hard water can also restrict flow through the valve, causing slow filling. If your washer hums during the fill cycle but no water enters, or water enters but only hot or only cold regardless of the temperature setting, or the dispenser compartments stay dry during the cycle, the water inlet valve has likely failed. This genuine OEM GE part directly replaces WH13X26637, WH13X24386, and WH13X10066. Fits GE and Hotpoint front-load washers. Moderate 30–45 minute DIY repair that restores proper water fill and temperature control.
