Hi.

The motor on this washer is reversible. By gliding on the motor plate it’s regulating the tension on the belt.More tension - grater the speed.
Check both pulleys, belt, drain pump pulley, motor plate.
The belt isn’t suppose to slip.
Here are the breakdown diagrams and 01-Base & Motor parts for Maytag MAV3855AWW - AppliancePartsPros.com

Post the results.
