Samsung WA88V4 Washing Machine Repair (Part 2 of 2) - Motor

Symptoms:

• Upon Power ON, all Wash/Rinse/Spin Mode are not working.
• Both drum and pulsator are not rotating at all at any mode.

Findings:

• Even after replaced Gear Mechanism and Rubber Belt but still not working
• Found out the AC Motor was burnt, and capacitor was broken

2. Washing Machine motor (Model: WAS165WTVA) is burnt, need to get replacement.
3. AC Motor Start/Run Capacitor (CBB65, 8uF) is not working. Measured Value = 6.97nF (broken)
4. New OEM AC Motor (Model: WAS165WTVA, 150W)
5. New AC Motor (180W ~ 220W) Wiring & Functional Check
• Red  - Blue   : 32.1 Ohm
• Blue - Purple: 31.6 Ohm
• Red  - Purple: 63.1 Ohm
• Blue is Common, AC Motor Start/Run Capacitor will be connected to Red and Purple
6. Calculation to get suitable AC Motor Start/Run Capacitor. Recommended: 12uF ~ 16uF
7. New AC Motor Run Capacitor (CBB60, 435V, 16uF). Measured Value = 16uF
8. New Motor and Start/Run Capacitor wiring connection diagram
9. New Motor + New Capacitor Testing: For Clock-Wise (CW) rotation
10. New Motor + New Capacitor Testing: For Counter-Clock-Wise (CCW) rotation
11. Install new capacitor (16uF) and new motor
12. Install new rubber belt

Tools required:

• Screwdriver
• T-Shape Wrench

Cost involved:

• WA88V4 OEM AC Motor (Model: WAS165WTVA) = US$22 ~ US$25
• CBB60/CBB65 AC Motor Start/Run Capacitor 450V 8uF = US$2 ~ US5

Info Share:

• When a motor first starts up, it needs more power than once it runs continuously. This extra boost of power is supplied by the capacitor, which acts as a battery to store power for when it is needed.
• If the washing machine capacitor is bad, there may not be enough power for the motor to start, and your washing machine may not work at all. However, the motor may try to pull excessive current, which can cause the motor's windings (the coils of wire inside the motor) to overheat and potentially burn out. Your washing machine might run but be slow and not work properly or efficiently.
