My Washer started out by not washing on the low wash cycle but would work fine in the high speed cycle,in the low speed cycle it makes a clicking sound and it also hums, now in the spin cycle it does the same thing and won't m/t out the water and makes the same clicking sound and hum.

Check for a broken motor coupler; also check for obstruction in the pump.

If it works in high speed but not low, I would check the timer for burnt contacts, just pull the cover off if it is metal.
If ok, I would pull off the outer panel and check the motor for overheating in slow speed operation.
