Based on your details, I would first check the drain pump to see if it's locked up due to a piece of clothing stuck inside the pump. You can remove the pump from the motor leaving the two hoses attached and then see if the motor will start. If it continues to just hum instead of starting, then it may be losing the start voltage. The motor needs start voltage and run voltage in order to start. The motor will just hum if it's not getting the start voltage. The start voltage circuit is usually the red and yellow wires. Check the yellow and red wires at the motor, capacitor and at the timer for a loose connection. Make sure the red and yellow wires are pushed in all the way at the timer terminal quick disconnect plug. 120 volts should be present when measuring across the red and yellow wires. Check the white wire with the black stripe too at the timer and motor. Washer filles with water then buzzes Google Search
