Possible Causes

Worn Franke motor brushes (on brushed models), Partially shorted motor windings, Severely dulled grind ring and impellers, Low supply voltage

How to Fix / Troubleshooting

Safety first: Turn OFF power before inspecting the unit.

  • Verify voltage: Have a qualified person check that the supply voltage at the disposer is within 10% of the rated value.
  • Inspect grinding components: Look for rounded or heavily worn impeller lugs and grind ring teeth. Excessive wear reduces grinding efficiency.
  • Limit load: Avoid hard items like bones and fibrous waste. If performance is still poor, internal components are likely worn out.
  • Replace worn parts: Replace the Franke grinding plate and grind ring or the entire disposer if the motor is also weak.
