Possible Causes
Failed internal shaft seal, Corroded Franke disposer grinding chamber, Cracked lower housing, Long-term rust from chemical cleaners
How to Fix / Troubleshooting
Safety first: Turn OFF power, unplug the unit, and place a pan under the disposer to catch drips.
- Confirm leak location: Run water through the sink without running the disposal and observe if water drips from the very bottom or seams of the housing.
- Check external fittings: Ensure the discharge elbow and side connections are not the source. Tighten or reseal if necessary.
- Assess corrosion: If water clearly emerges from the bottom or through rust holes, the internal seals or chamber are compromised.
- Replace unit: Internal leaks in a Franke disposer are not economically repairable. Replace the entire Franke disposer unit.
