Washer woorks well, just squeeks slightly when is stops spinning or finishes wash cycle...like it needs a little oil or belt or break is too tight? Any insight?

Also does this model have a "buzzer" to tell you when wash is complete? Thanks a whole bunch!

First thing, No, this unit would not have an end of cycle buzzer.
The squeak at the end of the spin cycle(s)is the brake rotor contacting the brake stator(like noisy brakes on a car).

This is a "dry brake" assembly and should not be lubricated(though some technicians do.)
It will require a special tool to dismantle the brake stator rotor assembly, and sanding the pads and stator with emory cloth solves the noise issue, as long as they are not too highly glazed. Otherwise replacement parts are required.

Some technicians use 2 screws to remove the stator, instead of the tool,

If you wish to attempt the repair yourself:

Unplug the power cord and remove hoses, and lay washer on it's back , or raise the front of the unit high enough to access the belt and pulley assembly under the unit.

Remove belt and plastic cap on the center of the drive pulley on the gearcase. carefully remove clip, cam , washers and pulley, It's best to line them up in order so ease the process when you reinstall them.

Remove 2 of the screws from the stator assembly(the stainless steel ring, has 10 to 12 screws holding the ring to the support assembly)and head to the hardware store and purchase 2 screws with the same threads only 2 inches long.

Install the longer screws and remove all the others, after installing the 2 .

Evenly remove the 2 screws until tension on the brake rotor spring(200 lbs psi) is released.

When the stator and rotor are removed, use emory cloth the sand the flat area of the stator ( you will see where the brake pads contact the stator). remove the rotor and sand the pad until all the glaze is removed, add a small amount of grease(a light coating) to the splines in the center of the rotor, and reverse procedure to reinstall and adjust cams.

It sounds like more than it is, and will probably take longer than the 20 to 30 minute a technician will take, but do able.

You're quite welcome, and good luck with the "tinkering".
