Troubleshooting Procedures

!WARNING

To avoid risk of electrical shock, personal injury or death, disconnect power to unit before servicing, unless testing requires power.

Drive Lug Adjustment

1.Disconnect power supply to unit.

2.Turn the drive pulley onto the shaft clockwise until all play is taken up.

3.Holding the pulley in this position, the distance between drive and pulley lugs should be 3/8”.

4.Turn pulley counterclockwise and check to see that the drive lug and pulley are making contact.

Note: There should always be clearance between the bottom of the pulley and the top of the stop lug to prevent the drive pulley from dragging on the drive lug, forcing it off the shaft.

Damper Pad Noise

3/8” Pulley Lug

Drive

Lug

Dry or poorly lubricated damper pads can result in a rubbing noise during the beginning and end of the spin cycle. If this condition is encountered, the damper pads should be lubricated or replaced. See “Damper Assembly” in Disassembly Procedures Section of this manual.

Pump Belt Adjustment

1/4”

1. Disconnect power supply to unit.

2.Pull motor forward so drive belt is tight.

3.With washer in an upright position, grasp the pump belt in the middle and flex. With the belt flexed, it should be tightened so that there is approximately 1/ 4” between the inside surfaces of the pump belt before movement of the motor is felt.

4.If necessary, tilt washer and loosen screws holding pump to base frame and position pump to attain the proper 1/4” dimension.
