If the high limit thermostat, thermal fuse, and motor windings are all functioning correctly, but your washing machine still doesn't work, there could be several other possible issues to investigate:
Lid switch or door lock: Washing machines often have a safety feature that prevents them from operating if the lid is open or the door is not securely closed. If the lid switch or door lock is faulty, the machine may not start.
Timer or control board: The timer or control board is responsible for initiating and controlling various cycles and functions of the washing machine. If it's malfunctioning, the machine may not respond or start.
Water inlet valve: The water inlet valve is responsible for allowing water to flow into the washing machine during the wash cycle. If it's defective or clogged, the machine may not fill with water, leading to a non-functional state.
Drain pump or hose: If the washing machine doesn't drain water properly, it may not proceed with the next stages of the cycle. Check the drain pump and hoses for any clogs or issues that may be preventing water from draining.
Drive belt or motor coupler: Front-loading washers typically have a drive belt, and top-loading washers often use a motor coupler to connect the motor to the transmission. If either of these components is broken or worn out, the machine won't agitate or spin properly.
Control panel or user interface: The buttons and knobs on the control panel or the digital user interface may become faulty over time, leading to issues with starting or selecting cycles.
Pressure switch or water level sensor: The pressure switch or water level sensor detects the water level in the washing machine. If it fails to register the water level correctly, it may prevent the machine from starting.
Capacitor: Some washing machines use capacitors to assist the motor during startup. If the capacitor is defective, it can cause the motor to malfunction.
If you're not familiar with washing machine repairs or troubleshooting electrical components, it's best to seek assistance from a qualified appliance repair technician. They can diagnose the issue more accurately and safely fix the problem. Additionally, some washing machine brands have specific diagnostic procedures, so referring to the manufacturer's documentation may also be helpful.
