ok fairly old model
you are going to have to pull it out away from wall , and fill washer , take bottom panel off and look to see where leaking from .
It could be the center post seal leaking or even the metal tub , this unit is 24 years old also
will need to replace the outer tub .
This is a link to the part which is discontinued due to the age
yes the part is no longer available ,
we only hold parts for seven years this is 26 years old sorry.
You would not even be able to get a service manual to show you how to take it apart.
