following check to verify brake is operating properly.
a. Turn off electrical power to washer.
b. Turn drive pulley one complete revolution in
agitation directly, then push drive pulley up against
brake.
c. Check for a .030 (.76 mm) minimum gap between
drive pulley and helix ramp surfaces.
NOTE: If gap is less than .030 (.76 mm), brake may not
stop washtub from spinning in required seven
seconds because brake will not close properly.

washer in the final spin operation.
NOTE: After installing complete tub module in washer
and all hoses have been reconnected, add at
least one quart of water to washtub to lubricate
pump seals. Running a pump without water
will ruin the seals.

minutes, normal spin speed should be
427 ± 25 RPM SLOW speed and 640 ± 25 RPM
FAST speed on one and two speed models; or
473 ± 25 RPM on SLOW speed and
710 ± 25 RPM on FAST speed on some two
speed models and all three speed models. Three
speed models never spin on the lowest speeds. If
