Kenmore 48102 Pressure Switch Troubleshooting

The Kenmore 48102 is a 12-cycle washing machine with a pressure switch that signals the cycle timer when the water level in the tub reaches the correct level. This starts the wash cycle. Air pressure activates the switch through a tube connected to a diaphragm below the tub. If the tube is clogged or the switch stops working, the Kenmore might not fill with water properly. Troubleshooting the switch should take less than an hour.

Putty knife
Screwdriver
3-foot length of 1/4-inch plastic tubing
Ohmmeter

Instructions

- 1
  Unplug the Kenmore's power cord at the end of a cycle when the tub is empty.
- 2
  Insert the blade of a putty knife into the front left corner below the top to pry up the top and pop out the retainer clip underneath. Repeat for the clip in the right corner.
- 3
  Pull off the corner trim on the control panel on the front left and right to expose the screws underneath.
- 4
  Remove the screws on both sides of the control panel with a screwdriver to tip the control panel forward. The pressure switch has a plastic tube connected to it on the back of the control panel.
- 5
  Pull the plastic hose off the port and connect one end of the 3-foot length of hose in its place.
- 6
  Unclip the two wires connected to the terminals on the switch. Each wire is crimped to a metal connector that pulls off the terminal blade on the switch.
- 7
  Test the ohmmeter by touching the two probes on the unit together. If the meter beeps or displays resistance, the device is working. Now clip the probes onto the two terminal blades on the pressure switch.
- 8
  Blow into the free end of the tube connected to the switch. If the switch is working, the ohmmeter will display slight resistance. If the ohmmeter display remains at zero, the switch is defective.
