Possible Causes

Sheared drive connection between motor and plate, Loose Franke turntable on shaft, Broken coupling inside disposer, Manufacturing defect

How to Fix / Troubleshooting

Safety first: Turn OFF power at the breaker before inspecting.

  • Observe plate movement: Look into the chamber while briefly turning the unit on (use extreme caution and keep tools and hands away). If the motor whines but the plate does not move, the drive connection is broken.
  • Manual test: With power off, try to rotate the plate by hand (using a tool). If it spins freely without resistance, it may be detached from the motor shaft.
  • Internal repair: Internal couplings in Franke disposers are not typically user-serviceable.
  • Replace disposer: Replace the entire Franke disposer unit if the grinding plate is no longer driven by the motor.
