Steps

Goal: Confirm the symptom, rule out pad and belt issues, then isolate the cause—motor, switch, or polish application.

  • Turn on the polisher and run it over the floor.
  • Good: The motor runs but the pad does not spin or the floor shows no shine—polish fault. Proceed to Check pad and belt.
  • Bad: The motor does not run—check power and the on/off switch.

Check pad and belt

Goal: Rule out pad installation and drive belt problems.

  • Inspect the pad—confirm it is locked onto the drive plate or pad driver. Remove debris that may jam the pad.
  • Unplug the polisher and open the housing. Inspect the drive belt for wear, cracks, or incorrect routing. Replace with an exact match if needed.
  • Good: Pad attached and belt intact. Proceed to Motor and polish.
  • Bad: Belt worn or loose—replace it. If the pad will not stay on, check the drive plate.

Motor and polish

Goal: Test the motor and polish application.

  • With the polisher on, check whether the motor shaft rotates. If it spins but the pad does not, recheck the belt and pad driver connection.
  • If the pad spins but the floor does not shine, confirm polish is being applied—check the dispenser and pad.
  • Good: Motor spins and polish is applied—the floor should gain shine.
  • Bad: Motor does not spin—switch or motor failed. Call a technician.

When to get help

Call a floor-care or appliance technician if:

  • You have replaced the pad and belt but the polisher still does not polish.
  • You hear grinding or burning from the motor.
  • You are not comfortable opening the housing or working with the motor.

Verification

  • The polisher pad spins and the floor gains shine.
  • No unusual noises from the motor or belt.
  • The pad and belt are intact and the polisher runs consistently.

Does the polisher run but not polish the floor?

Turn on the polisher. If the motor runs but the pad does not spin or the floor shows no shine, the polish function has failed.

Turn on the polisher. Check if the pad spins and if the floor gains shine. Good: motor runs but no polish—drive or application fault. Bad: motor does not run—check power and switch.

Is the pad installed correctly and free of debris?

A loose or jammed pad will not spin. Check installation and clear debris.

Inspect the pad. Confirm it is locked on. Remove debris. Rotate by hand—should turn freely. Good: pad attached and clear. Bad: pad loose or jammed—reinstall or clear debris.

Yes No

You can change your answer later.

Is the drive belt intact and correctly routed?

A worn or slipped belt prevents the pad from spinning.

Unplug and open the housing. Inspect the drive belt. Replace if worn or cracked. Confirm correct routing. Good: belt taut and intact. Bad: belt worn or loose—replace it.

Yes No

You can change your answer later.

Does the motor shaft rotate when the polisher is on?

If the motor spins but the pad does not, the belt or drive connection is the issue. If the motor does not spin, the motor or switch has failed.

With the polisher on, check if the motor shaft rotates. Good: motor spins—recheck belt and pad driver connection, or polish application. Bad: motor does not spin—switch or motor failed; call a pro.
