Possible Causes
How to Fix / Troubleshooting
Safety First: Immediately switch OFF power at the breaker. Water leaking into the motor area is an electric shock and fire hazard.
- Step 1 – Confirm leak origin: Dry the exterior of the unit. Run water without operating the disposal and observe. If water emerges from the bottom or reset button area, the leak is internal.
- Step 2 – Check sink flange first: Ensure the leak is not coming from above and running down the sides. Wipe around the sink flange and mounting ring to confirm.
- Step 3 – Do not open motor housing: Astracast disposals are generally not designed for internal seal replacement by end users. Opening the motor housing can compromise safety certifications.
- Step 4 – Plan replacement: If the internal shaft seal or grinding chamber is leaking, the safe and recommended repair is to replace the entire Astracast disposal unit.
- Step 5 – Dry area and inspect wiring: After removal, inspect the under-sink area and electrical junction box for water damage. Replace any corroded connectors.
Warning: Do not continue using a disposal that leaks from the bottom; it can cause electric shock and cabinet damage.
