This will take some skill to determine the problem and maybe a meter. Diagnostics should tell us what is wrong. Here are the steps with a video to see first to get you ready. Let me know what code you get.

ACTIVATING THE SERVICE DIAGNOSTIC TEST MODES
1. Be sure the washer is in standby mode (plugged in with all indicators off).
2. Perform the following sequence of movement using the cycle selector knob.
NOTE: AFTER RESET, sequence “a” through “e” must be completed within 6 seconds.
RESET - Rotate cycle selector knob counterclockwise one or more clicks to clear sequence.
a. Rotate cycle selector knob clockwise one click and wait ½ second.
b. Rotate cycle selector knob clockwise one click and wait ½ second.
c. Rotate cycle selector knob clockwise one click and wait ½ second.
d. Rotate cycle selector knob counterclockwise one click and wait ½ second.
e. Rotate cycle selector knob clockwise one click.
Successful activation of Diagnostic Test Modes will be indicated by all status LEDs (except for Lid Locked) flashing ON and OFF in half-second intervals.
NOTE: LED names may vary between makes and models.
When all LEDs are flashing, turn the knob until the “Done” light comes on.
Press the start button.
Turn the knob clockwise one click and observe if any LEDs flash in sequence.
If the Sensing, Prewash, and/or Soak LEDs are ON, the Fault Number is *****; if OFF, the Error Number is ***** The remaining LEDs (Wash, Rinse, Spin, and Done) represent the fault and error code in binary.
The code is read by reading what LEDs are on with the Sensing LED, (This is the fault) and then what LEDs are on when it goes out, (This is the error).
Watch the alternating codes and let me know what lights, if any are on when the Sensing LED is on and then what lights come on when it goes off.
After you read the first code if you turn the knob one click at a time clockwise it will display the next code if any are present.
