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.
