Four on the floor
- ensure the unit is level and all four levelling legs are properly adjusted and securely
on the floor. The objective is for each of the four legs to carry equal weight; four on the floor.
As little as
1/4 or 1/2 turn on a single levelling leg can be significant.
A helpful quick check is to place your left
hand on the top left front corner and your right hand on the top right rear corner. Then, push the washer
in the direction of your hands and note force required to remove the weight from the front leg. Now
reverse hands, i.e., right in top right front corner and left in top left rear corner, and note the force
required to remove weight from the front leg. The two forces should be equal.
5.
With the basket empty of clothes and water, run the T11 test and check for acceptable vibration or
movement. To run T11, remove power to unit for 30 seconds. Reapply power, press
Signal
button,
press
Delay Start
button, press
Signal
button again, press
Delay Start
button again. When
T01
is
displayed, rotate the
Cycle Select
knob until
T11
is displayed, then press the
Start
button. Note the test
does not rebalance the load. Press
Power
to quickly end the test for an extreme out-of-balance
condition. Once the unit reaches 400 rpm, press the
Start
button again, the washer will then ramp up to
high-speed spin.
Note:
Up to 1/4-inch movement is normal operation. If OK, proceed to step B. If not OK, adjust the legs and/or
check for a machine structural or mechanical fault (see next Section).
6.
Place 1 or 2
dry
, tightly rolled up, bath
towels in basket and tape them in place
to a baffle inside against the basket
centered front to back; see picture. The
weight of the towel(s) should be about 1-
1.5 lbs;
do not exceed 2 lbs.
Ensure the rear legs are level and the rear jam nuts are wrench tight against the washer or pedestal bottom;
(
See picture below)
. Next, run T11 and adjust the front legs for minimum vibration or movement at ~ 400 RPM.
Secure the front jam nuts wrench tight and run T11 again to confirm the legs are set properly for minimum
vibration or movement while the washer is spinning at 400 RPM. Press on the washer top left front corner
toward the top right rear corner with your hands and note if any increased vibration. Then, press on the top right
front corner toward the top left rear corner with your hands and note if any increased vibration.
If pressing either corner
decreases/lessens
vibration or movement, the legs are still out of adjustment and must
be corrected. If pressing either corner
increases/worsens
vibration or movement, the legs are properly set.
Note:
Proceed with Steps 8-9
only
if front load
washer vibration and movement cannot be adjusted
to acceptable levels.
7.
Inspect all four feet for good condition. If any of the rubber feet is
damaged as in the pictures below, it can cause front load washer
vibration.
8. If installed on a pedestal, confirm all four washer-to-pedestal bolts are wrench tight.
