      • 🔧 Step-by-Step Repair Instructions

      ⚡

      🔧 Step 1: Test switch continuity

      1. Unplug the washing machine power cord from the wall outlet completely.
      2. Locate the lid switch assembly mounted underneath the top panel of the washer, positioned 3 inches from the right edge when facing the front of the machine.
      3. Identify the wire harness connector attached to the lid switch – it’s a white rectangular plug with 3 wires (typically white, gray, and orange).
      4. Press the locking tab on the connector and pull the harness away from the switch terminals to disconnect it.
      5. Set your digital multimeter to the continuity or ohms setting (Ω symbol), typically the lowest resistance range available.
      6. Touch the multimeter’s red probe to the common terminal on the switch (the single terminal separated from the pair).
      7. Touch the black probe to one of the two remaining terminals on the switch.
      8. Press the lid switch actuator arm down with your thumb – this simulates the lid closing position.
      9. Watch the multimeter display – it should read 0 ohms or beep (indicating continuity) when the actuator is pressed.
      10. Release the actuator arm – the multimeter should read OL (open line/infinite resistance) or stop beeping.
      11. Move the black probe to the third terminal and repeat the press-and-release test in steps 8-10.
      12. Test between the other two terminals by moving the red probe – one terminal pair should show continuity when pressed, the other should show continuity when released.
      13. If the switch shows no continuity in any position or shows continuity in both pressed and released positions on the same terminal pair, the switch has failed and requires replacement (part number WP54-1058).
      14. If all tests pass correctly, reconnect the wire harness by pushing the connector onto the switch terminals until you hear an audible click.

      🛠️ Step 2: Clean pressure hose for blockages

      1. Locate the pressure hose at the bottom left of the washer tub, approximately 8 inches from the left edge—it’s a clear or white rubber tube, approximately 1/4 inch in diameter, running from the outer tub to the pressure switch.
      2. Trace the hose upward to find the pressure switch mounted on the right side of the control panel area, approximately 14 inches from the bottom of the cabinet.
      3. Using needle-nose pliers, squeeze the spring clamp securing the hose to the pressure switch fitting and slide the clamp 2 inches down the hose away from the connection point.
      4. Twist the hose back and forth while pulling to remove it from the pressure switch nipple—you’ll feel it release after rotating approximately 1/4 turn.
      5. Move to the lower connection point at the tub and repeat: squeeze the spring clamp with pliers, slide it down 2 inches, then twist and pull the hose off the tub air dome nipple.
      6. Hold the hose up to a light source and look through it—blockages appear as dark spots or completely obscure light passage.
      7. Fill a sink or bucket with warm water mixed with 2 tablespoons of dish soap.
      8. Submerge the entire hose in the soapy water for 3 minutes to loosen debris.
      9. Use a pipe cleaner or a 24-inch length of 14-gauge electrical wire to push through the hose from one end to the other, dislodging any lint, detergent residue, or mineral deposits.
      10. Hold one end of the hose under running tap water and flush water through for 30 seconds, allowing debris to exit the opposite end.
      11. Blow forcefully through the hose—air should pass freely without resistance if the blockage is cleared.
      12. Shake the hose vigorously to remove remaining water droplets before reinstallation.

      ⚙️ Step 3: Check hose connections

      1. Turn off both the hot and cold water supply valves located on the wall behind the washer by rotating them clockwise until they stop.
      2. Pull the washer approximately 2 feet away from the wall to access the rear panel where the inlet hoses connect.
      3. Locate the two inlet hoses at the top-right corner of the washer’s back panel—the left hose connects to the hot water inlet (marked with red), the right connects to cold water (marked with blue).
      4. Inspect each rubber hose washer inside the threaded coupling at both the wall valve end and the washer inlet end—you should see a black rubber washer sitting flat inside each coupling.
      5. If any washer appears cracked, compressed flat, or missing, unscrew that hose connection by turning the coupling counterclockwise with slip-joint pliers or by hand.
      6. Remove the old washer by prying it out with a flathead screwdriver and press a new 3/4-inch hose washer (part number PM14X51) into the coupling groove until it sits completely flat.
      7. Check the inlet screens inside both washer inlet ports—they appear as small cylindrical mesh filters, approximately 1/2-inch diameter.
      8. If you see debris or sediment on the screens, use needle-nose pliers to carefully grip and pull each screen straight out, then rinse under running water.
      9. Reinsert clean screens by pressing them back into the inlet ports with your thumb until they sit flush with the port opening.
      10. Hand-tighten each hose connection onto the washer inlets by turning clockwise until snug, then use slip-joint pliers to turn an additional 1/4 turn (90 degrees).
      11. Reconnect hoses to wall valves using the same tightening method—hand-tight plus 1/4 turn with pliers.
      12. Turn on the water supply valves counterclockwise, then check each connection for drips or spray during a 30-second observation period.

      🔩 Step 4: Replace switch if faulty

      1. Grip the faulty switch (lid switch part number WH12X10355 or water level pressure switch part number WH12X10065, depending on which tested faulty) and pull the wire harness connector straight away from the switch terminals with steady pressure until it separates.
      2. For lid switch replacement: Press the plastic tab on the switch mounting bracket located on the top rim of the washer tub, approximately 3 inches to the right of the center hinge point, then lift the switch assembly upward and out of its slot.
      3. For pressure switch replacement: Use a 1/4-inch nut driver to remove the single mounting screw securing the switch to the control console bracket on the right interior panel, then pull the switch free.
      4. Disconnect the clear air pressure tube (pressure switch only) by gripping it 1 inch from the switch nipple and pulling straight off with a slight twisting motion—you’ll feel it release from the barbed fitting.
      5. Position the new switch in the same orientation as the removed one—the wire connector should face toward the front of the machine for lid switches, or downward for pressure switches.
      6. For lid switch: Align the two plastic tabs on the switch body with the corresponding slots in the mounting bracket, then press down firmly until you hear and feel a distinct click.
      7. For pressure switch: Align the mounting hole and secure with the 1/4-inch mounting screw, tightening until snug but not overtightened (approximately 10-12 inch-pounds of resistance).
      8. Reconnect the air pressure tube (pressure switch only) by pushing it straight onto the barbed nipple until it bottoms out—you should have 1/4 inch of tube overlap on the fitting.
      9. Push the wire harness connector onto the switch terminals until it clicks into place—test the connection by gently pulling backward; it should not separate.

      đź“‹ Step 5: Test water level detection

      1. Locate the pressure switch on the right side of the washer frame, approximately 18 inches up from the bottom, mounted to a vertical bracket with a single Phillips-head screw.
      2. Identify the clear or translucent plastic air hose (approximately 1/4-inch diameter) connected to the bottom port of the pressure switch and follow it down to the tub.
      3. Disconnect the air hose from the pressure switch by squeezing the retaining clip with needle-nose pliers and pulling the hose straight down with a twisting motion.
      4. Set your multimeter to continuity mode (audible beep setting).
      5. Unplug the wire harness from the pressure switch by pressing the locking tab on top and pulling straight away from the switch body.
      6. Identify the three terminals on the pressure switch connector – they’re typically arranged in a row and labeled (from left to right when facing the switch): COM (common), NO (normally open), and NC (normally closed).
      7. Touch one multimeter probe to the COM terminal and the other to the NO terminal – you should hear no beep with the tub empty.
      8. Blow gently into the disconnected air hose port on the pressure switch to simulate water filling the tub – you’ll need to maintain approximately 1-2 PSI of air pressure.
      9. While blowing into the port, listen for an audible click from inside the pressure switch and verify the multimeter now beeps, indicating the switch has changed state.
      10. Stop blowing and confirm the multimeter stops beeping and you hear another click as the switch returns to its original position.
      11. If the switch clicks and the continuity changes as described, reconnect the air hose until you hear it snap into place and plug the wire harness back onto the switch.
      12. If no click occurs or continuity doesn’t change, replace the pressure switch (part number WH12X10065).
