The F32 error code indicates a water level pressure switch failure. This is normally caused by wiring connection problem or a failed pressure switch. If you are able to unplug the washer and remove the top panel, you can check the wiring connections between the control board and the water level pressure switch. To remove the top panel (with the washer unplugged), take out the screws at the very back of the top panel and slide the panel back and then pick it up and remove it from the top of the washer. The pressure switch is on the top of the right side panel toward the back of the washer (Key 38 in the first image below).
If the wire harness connection between the pressure switch and the control board is okay, then you will probably need to replace the pressure switch to correct this problem. The part number for the pressure switch is 8181695. You can order this part from the Sears PartsDirect website
The F28 error code indicates a communication error between the main control board and the motor control board at the bottom of the washer by the drive motor (Key 1 in the second image). A loose wiring harness connection can cause this problem. It can also be caused by a failed motor control board, a bad drive motor or a defective main control board. You may be able to check the wiring harness connection to the motor control board by unplugging the washer and removing the bottom from service panel. To remove this panel (with the washer unplugged), take out the screws at the very bottom of the panel and then pull the panel down and out to remove it. Access to the motor control board may be limited. You may be able to check to make sure that wiring connections are firmly secured on the motor control board. If the connections are okay and you continue to get the F28 error code, you may need to replace the motor control board. I recommend calling a service technician to diagnose this problem before replacing the motor control board.
