Error Code 3C

The washer's motor isn't spinning correctly

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 (a screw) has entered the motor; Motor overloaded due to too much laundry (non-sensing); Motor hall sensor terminal is not connected; PBA fault or weak motor driving signal from PBA; Unstable relay operation; Erroneous operating signals from the motor hall sensor; IPM terminal of the 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 the motor connector terminal connections and contacts

2. 2

   2. Plug out the motor connector and measure resistance at any two of the three motor terminals — should be 6.0 ohm at 25 degrees C

3. 3

   3. Check if 3E is displayed due to motor overloading from too much laundry — reduce load

4. 4

   4. Check the motor hall sensor — measure resistance on the main PCB motor connector between pins 1 and 3, and pins 1 and 4 of the four pins — should be approximately 2 to 4 megaohm

5. 5

   5. Check voltage at the hall sensor when power is on

6. 6

   6. Check whether the stator of the motor cover is damaged

7. 7

   7. Check for coil disconnections due to foreign material

8. 8

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