If your washing machine is not starting or agitating but is able to spin fine and fill with water, there could be several potential causes for this issue. Here are some common reasons why this might be happening:
Lid or Door Switch: Many washing machines have a lid or door switch that prevents the machine from starting if the lid or door is not properly closed. If the switch is faulty or not making proper contact, it could prevent the machine from starting or agitating.
Timer or Control Board: The timer or electronic control board in the washing machine controls various functions, including the agitation cycle. If this component is defective or malfunctioning, it may prevent the agitation cycle from starting.
Drive Belt: Washing machines use a drive belt to transfer power from the motor to the agitator and drum. If the drive belt is broken or loose, the agitator won't be able to move, even though the motor might be spinning the drum during the spin cycle.
Motor Coupling: Some washing machines use a motor coupling to connect the motor to the transmission. If the motor coupling is broken or worn out, it can cause the agitator not to function while still allowing the spin cycle to work.
Agitator Dogs (Agitator Cogs): Top-loading washing machines with a dual-action agitator have small plastic components called agitator dogs that can wear out over time, causing the agitator not to agitate.
Transmission or Clutch: Issues with the transmission or clutch assembly can also lead to problems with agitation. If these components are faulty, the agitator may not move even though other functions of the washing machine work fine.
To diagnose and fix the problem correctly, it's best to contact a qualified appliance repair technician or the manufacturer's service center. They can properly inspect and diagnose the issue with your washing machine and recommend the necessary repairs. Avoid attempting any repairs if you are not experienced in appliance repair, as it could lead to further damage or personal injury.
