Error Code 3C

The washer's drum motor can't spin properly

Also displayed as: 3C

What This Means

Motor spin net is not engaged; Motor's 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; Motor driving error from the PBA is weak; 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 winding coil — plug out the connector and read the resistance between any two of the three motor terminals. Should be 6.0 Ohm at 25°C

2. 2

   2. Check the motor connector terminals on motor for contacts and connections

3. 3

   3. Check if the hall sensor terminal is faulty — if so, replace the washing motor/hall sensor

4. 4

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

5. 5

   5. Check the resistance on the main PCB connector — Approx. 2 to 4 MOhm

6. 6

   6. Check the voltage when the power is on

7. 7

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