Verifying the Vibration Switch Function
1.
Open the control panel cover.
2.
Start the extraction mode.
3.
After reaching maximum RPM, switch over the vibration
switch by moving the flexible control element manually.
The extraction cycle should stop. If extraction does not
stop, the vibration switch requires adjustment or is defective.
Belt Inspection, Adjustment,
and Replacement
On a new washer or after a belt replacement, make an inspection
of the belt tightness:
1.
After the first 24 hours of operation;
2.
After the first 80 hours of operation; and,
3.
Every 6 months or 100 hours of operation, whichever
comes first.
Belt Inspection and Adjustment
1
. Turn off power to washer at the circuit breaker or fuse box.
2.
The belts are accessible after the rear or side cover has been
removed. Check the belts to make sure they are neither too
tight or too loose. Change the belts if they are worn out or
damaged. Always change a complete set of the belts for one
transmission with the same type of belts being removed.
3.
Be sure that the belt pulleys are aligned by laying a straight
edge along the pulley faces. If all points are touching the
straight edge, the pulleys are aligned.
4.
Checking the belt tension requires a straight edge and a belt
tension gauge. Place the straight edge from the drum pulley
to the motor pulley. Belt tension is correct for Model MFS80
when a 12.1 lb (5.5 kg) force applied to the midpoint of the
belt between the two pulleys deflects the belt 4/5" (20 mm).
Belt tension is correct for Models MFS100 and MFS125
when a 15.4 lb (7 kg) force applied to the midpoint of the
belt between the two pulleys deflects the belt 4/5" (20 mm).
Belt tension is correct for Model MFS180 when a 2.6 lb
(1.2 kg) force applied to the midpoint of the belt between
the two pulleys deflects the belt 1/2" (12.3 mm). Belt tension
is correct for Models MFS230 and MFS275 when a 4.9 lb
(2.2 kg) force applied to the midpoint of the belt between
the two pulleys deflects the belt 0.35" (9 mm). To adjust the
belt, first loosen the locking nut and loosen or tighten the belt
as necessary. Retighten the locking nut when adjusted and
recheck.
5.
Replace rear panel of washer. Turn on power at circuit breaker
or fuse box.
