Customer Questions and Answers for Water Level Pressure Switch by Whirlpool

4.89 (64)
By: Whirlpool
Part Number: OEM20943129
Manufacturer Part Number: W11417619

This water level pressure switch senses air pressure from the tub and signals the control to stop filling at the correct level. Replacing a weak or failed switch restores proper filling, helps prevent over/underfilling, and allows cycles to advance.

  • Monitors tub water level via the pressure hose and sends the level signal to the control
  • Stops water flow at the target level so wash, rinse, and spin can begin
  • Common symptoms of a failing switch: continuous filling, overfilling or underfilling, cycle won't advance past fill/sensing, or stops with water still in the tub
  • A cracked, kinked, or blocked pressure hose can mimic switch failure—inspect during diagnosis
What's included: 1 water level pressure switch Install notes:
  • Disconnect power and turn off water supply before servicing
  • Access the switch from the console/top or rear panel per your model; note wire orientation
  • Transfer and firmly seat the pressure hose; inspect it for kinks, cracks, or blockages and replace if damaged
  • After installation, run a fill test; some models may require a diagnostic calibration—see the tech sheet or user manual

Hi Cathy. The F1E2 code is MOTOR CONTROL UNIT ERROR. The Motor Control Unit has internal failure. If failure occurs during high-speed spin, the door unlocks after 3 minutes.Possible Causes/Procedure - Verify the shipping system, including shipping bolts and spacers, are removed, and that power cord is out of the washer. - Check if washer is on a dedicated circuit. Other devices on same circuit can create line noise and cause this issue. - Unplug washer or disconnect power. - Check the neutral feed to the MCU and CCU from the AC line filter. - Make sure all wire harness connections between the Motor & MCU, and MCU to CCU, are not broken or with wires detached, and that connector internal pins are visible. - Make sure that all the connectors are fully seated. - Plug in washer or reconnect power. - Verify the washer operation by running the Diagnostic Test cycle. See page 5. - After the diagnostic test has finished, unplug washer or disconnect powerand wait for 15 seconds. Motor control unit part # WPW10384843. Thank You.
