How to Fix / Troubleshooting
Safety: Unplug the machine before inspecting moving parts.
- Localize the noise: Run the machine briefly and listen to determine whether the noise comes from the vacuum, pump, or brush area. Then disconnect power.
- Check for loose mounts: Tighten mounting bolts on the vacuum motors, solution pump, and brush motor. Replace missing hardware.
- Inspect for debris: Look for foreign objects in the vacuum intake, fan housing, or brush head. Remove any debris carefully.
- Assess bearings: If a motor emits a high-pitched whine or grinding, its bearings may be failing. Replace the affected Prochem vacuum motor or pump.
