Humming/Whirling Noises on your Amana Washer:
Noises that newer top load washers make can be completely different than older washers. The humming/whirring noise is very common and part of normal operation:
The Humming/Whirling noises you would hear during the agitation/wash or spin portions of the cycle are caused by the motor. You may hear an intermittent humming/whirling noise during the agitation/wash portion of the cycle as the motor turns the washer basket clockwise and counterclockwise.
You may also hear a humming/whirling noise during the spin portion of the cycle as the motor winds up to turn the washer basket at a higher speed.
The pump will run continuously throughout the drain cycle. You may hear a humming sound from the pump, this may be more noticeable once the majority of the water has been drained. These sounds are part of the normal washer operation.
