Also displayed as: 3C (upper) / 3C (lower)

What This Means

PBA connector terminal is not connected; 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 error 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 connector and read resistances at any two of the three terminals on motor

3. 3

   3. For upper washer motor: resistance should be 10.2 to 12.4 ohms at 25°C

4. 4

   4. For lower washer motor: resistance should be 7.6 to 8.4 ohms at 25°C

5. 5

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

6. 6

   6. Check for coil disconnections between pins (pins 2 and 4, and 3 and 4 on four-pin connector)

7. 7

   7. Check for foreign material in the rotor/stator gap

8. 8

   8. Check the resistance — approximately 2 to 4 megaohms

9. 9

   9. Check the voltage when the power is on

10. 10

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