Caution:
Please read our safety
information before attempting any testing or repairs.
Before checking the motor coupler, unplug
the washer or shut off the power at the fuse
box or breaker
panel to avoid an electrical shock hazard. Also, turn off
the water supply to the washer at the valves.
Washers
with a direct drive motor have a motor coupler instead of a belt . The motor coupler consists of three plastic
disks (or tri-stars) with interlocking tabs. Those tabs can wear
and break and which results in slippage. The slippage causes
little or no power to be transferred to the transmission. A worn
motor coupling can result in weak or no movement of the agitator and spin basket. Inspecting the motor couplers
requires removing the motor, which is fairly easy to do.
Remove the cabinet.
Locate the motor. The pump is mounted to one side of the motor.
You do not have to remove the hoses from the pump unless they
prevent you from moving the pump out of your way. If you must
remove the hoses, label where they connect first. To disconnect
the hoses, pinch the wire clamps with pliers (or loosen the screw)
and slide the clamp farther up the hose. Slide the hose off of
the pump port.
There are two clips that secure the pump housing
to the motor. Use a screwdriver to pry up the clips and remove
the cover. Next, slide off the pump to reveal the motor. Disconnect
the wiring harness from the motor, do not pull on the wires themselves.
The motor typically is secured with retaining clips and bolts.
Remove the bolts and use a screwdriver to pry up the clips (if
present). Remove the motor.
Mounted on the shaft of the back of the motor
you will find the motor coupler. Separate the three disks and
inspect them for damage. If you find cracks or excessive wear,
replace the coupler.
