Error Code 3C

The washer motor cannot spin or is struggling to turn

Also displayed as: 3C

What This Means

Motor spin net is not engaged; Motor internal coil is damaged (short-circuited or cut); Hall sensor terminal is not connected; Foreign material (such as a screw) has entered the motor; Motor overloaded due to too much laundry (non-sensing); Motor hall sensor terminal is disconnected; PBA fault causing weak motor drive signal; Unstable relay operation; Erroneous operating signals from the motor hall sensor; IPM terminal of main PBA is not connected; DD motor cover is out of place; PCB housing terminal is not connected; DD motor fault

First Thing to Check

Parts Involved

How to Fix

1. 1

   1. Check motor terminals for proper connections and contacts

2. 2

   2. Plug out the motor connector and read resistances at any two of the three motor terminals — should be 6.0 ohms at 25 degrees C

3. 3

   3. Check motor winding coil: wire order is Blue, White, Red from the right; resistance between Blue-White, White-Red, and Red-Blue should each equal 15 ohms

4. 4

   4. Check the hall sensor connector and replace if the hall sensor terminal is faulty

5. 5

   5. Check whether the motor cover stator is damaged

6. 6

   6. Check rotor and stator for foreign material and coil disconnections

7. 7

   7. Check resistance on the main PCB (between pins 1 and 3, and 1 and 4 of the four pins) — approximately 2 to 4 megaohms

8. 8

   8. If the PBA control circuit is faulty, replace the PBA

9. 9

   9. Check voltage when power is on
