WD21X25468 Dishwasher Water Level Pressure Sensor

Key Features

• Precise Water Level Monitoring: Accurately measures the water pressure and depth inside the dishwasher tub to ensure optimal fill levels, maximizing detergent dissolution and cleaning efficiency.
• Active Flood Prevention: Acts as a critical safety switch that immediately signals the control board to shut off the water inlet valve if the water level rises too high, preventing costly kitchen overflows.
• Durable Sensor Housing: Manufactured with a high-impact, moisture-resistant polymer specifically engineered to withstand the hot, humid, and vibration-heavy environment underneath the dishwasher sump.
• Direct Fit: Designed to exact factory specifications for a perfect, leak-free seal against the pressure chamber, ensuring seamless communication with your dishwasher's main electronic control board.
• Plug-and-Play Connection: Features a standard electronic terminal port for quick, wire-free snapping directly into the appliance's existing wiring harness, making replacement straightforward.

Compatibility & Fitment

This electronic pressure sensor is a direct replacement for a wide family of dishwashers. Compatible brands include:

• GE (General Electric)
• Hotpoint
• Cafe
• Profile
• Monogram
• Haier

When to Replace

• Constant Draining: The dishwasher drain pump runs continuously, even when the tub is completely empty, because a faulty sensor is falsely detecting a flood condition.
• Failure to Fill: The wash cycle starts but no water enters the tub, often accompanied by a low-water, "H2O", or similar error code on the control panel display.
• Overfilling and Leaking: The water level rises too high and eventually leaks out of the front door because the sensor fails to signal the inlet valve to close.
• Flashing Control Board Lights: Unexplained error beeps and flashing lights immediately upon starting a cycle, indicating the control board has lost communication with the pressure sensor.

Installation Tips

• Safety First: CRITICAL: Disconnect power at the circuit breaker and shut off the hot water supply valve under the sink before performing this repair to avoid electrical shock or flooding.
• Accessing the Sensor: The sensor is located underneath the dishwasher. You will need to remove the lower kickplate/toe panel to access the sump area. On some installations, gently pulling the unit out may provide better leverage.
• Clear the Chamber: PRO TIP: Before installing the new sensor, inspect the pressure chamber port it plugs into. Built-up grease, soap scum, or food debris can clog this area, causing the sensor to misread. Clean it out thoroughly with a small brush or pipe cleaner.
• Secure the Seal: Ensure the rubber O-ring or gasket is seated properly and perfectly flat when inserting the new sensor into the assembly. A pinched O-ring will result in a slow, continuous drip under the machine.
