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

Cindy for Model Number MHWZ600TB01 EPIC Z MAYTAG FRONTLOAD WASHER

I am not seeing any error codes just the add garments and everything else goes on as normal, until I press start then I hear a double click from the backside of the washer and the door unlocks then the machine turns off - or it spins over once then unlocks the door and all lights stay on.There is still water in the washer and it will not drain either...... Do you have any instructions to install these parts? If so where can I get them? Which part do you think it could be if either? Could I be missing something to check?

Answer

Hi Cindy. Start a new cycle by opening and closing the door to let the control board another load is received.Does the door lock light come on? The door latch switch is part # W11417619. Can you press pause / cancel and the machine should spin and drain? Use a shop vacuum to drain water. If the pressure switch is not satisfied then it will not allow any function. Part # is W11417619. Remove power. remove the 3- torx screws (T-15/20) from the back of the top. Slide the top rearward and up to remove. Then on the front RT. back corner is the pressure switch. Part # is W11417619. Remove the hose. Blow back into it towards the tub. Did you "feel" any obstruction removed as you were blowing? Lint restrictions (plugged vent system needing cleaning) or scum build up ? Washer magic is part #W10549845. Thank you.
