Possible Causes

Faulty upright position switch, Stuck actuator lever, Shorted control PCB, Misadjusted linkage

How to Fix / Troubleshooting

Safety first: Unplug the machine immediately if the brush runs when upright.

  • Check for mechanical sticking: Move the handle between upright and reclined positions several times (with machine unplugged) to see if the actuator lever moves freely.
  • Inspect pivot area: Look for debris or broken plastic around the pivot that could prevent the upright switch from being triggered.
  • Do not use until fixed: A brush running in upright position can damage flooring and is a safety concern.
  • Professional repair: The upright switch or PCB will likely need replacement. This requires opening the body and should be done by a technician.

Do not attempt to bypass the upright interlock; it is an important safety feature.
