Weekly
1. For variable-speed models only, clean the AC drive box
filter(s) weekly or more frequently as needed:
NOTE: If the fan filter service indicator light is on, the fan filter
must be cleaned immediately to prevent possible damage. Press
the thermostat button to reset the indicator light.
NOTE: If filter indicator is ignored, repeated resets might
shorten life of drive. Clean filter regularly to avoid indication
prompt.
a. Open the top cover.
b. To remove the filter, grasp the filter handle and pull straight
up.
c. Wash the filter with warm water and allow it to air dry. As an
alternative, the filter may be vacuumed clean.
IMPORTANT: The control module cover and fan filter must be
in place for the fan to properly cool the AC drive. Failure to
observe this warning will void the warranty and could lead to
expensive AC drive repair.
2. Check the machine for leaks:
a. Start an unloaded cycle to fill the machine.
b. Verify that the door and door gasket do not leak.
c. Verify that the drain valve is operating and that the drain
system is free from obstruction. If water does not leak out
during the first wash segment, the drain valve is closed and
functioning properly.

Monthly
NOTE: Disconnect power to the machine at its source before
performing the monthly maintenance procedures.
1. Use the following procedures to determine if the V-belt(s) require
replacement or adjustment. Call a qualified service technician in
either case.
a. Check the V-belt(s) for uneven wear and frayed edges.
b. For groove-pulley drive systems, verify alignment by placing
a straightedge across both pulley faces. The straightedge
should make contact with the pulleys in four places.
c. For flat-pulley drive systems, verify the allowable distance of
the belt from the edge of the pulley. Refer to the
Operation/Maintenance Manual for pulley alignment
specifications.

Monthly
d. For variable-speed models only, verify that the V-belts are
properly tensioned by applying a set force to the belt and
measuring the deflection to determine the belt tension. Belt
tension measurements should be taken as close to the center of the
belt span as possible. Refer to the Operation/Maintenance
Manual for belt tensioning specifications.
NOTE: Hoses and other natural rubber parts deteriorate after
extended use. Hoses may develop cracks, blisters or material wear
from the temperature and constant high pressure they are
subjected to.
2. Check all hoses for any visible signs of deterioration. Any hose
showing signs of deterioration listed above should be replaced
immediately.
NOTE: All hoses should be replaced every five years.

3. For 80-pound and 125-pound capacity models only, lubricate
the bearings and seals each month OR after every 200 hours of
operation.
a. Use a premium-grade lithium-based #2 grease. Never mix two
types of grease, such as petroleum and silicone.
b. Pump the grease gun slowly, permitting only the following
number of strokes:
2 strokes for bearing grease fittings
2 stroke for seal grease fittings
Do not pump the grease gun until grease comes out of the
bearing housing. This can result in over-lubrication and can
cause damage to the bearings and seals.
4. Remove the back panel and check the overflow hose and drain
hose for leaks.
