Hi,

A105

Nice washer!

A copy:

Maytag Dependable Care washer - wont agitate:

Check for a seized transmission, if you cannot turn the belt by hand the transmission may be seized. There is also a drive lug that may need to be adjusted, the drive lug is under the center (Trans) pulley.

One direction is spin and other direction is for agitation.
