How to Fix / Troubleshooting
Safety First: Do not repeatedly reset a tripping GFCI. Turn OFF the breaker and unplug the unit.
- Step 1 – Inspect cord and plug: Look for cuts, crushed sections, or burn marks on the Tweeny power cord. Replace if damaged.
- Step 2 – Check for leaks: Examine the sink flange and mounting assembly for drips onto the electrical area.
- Step 3 – Dry thoroughly: If moisture is present, dry the area and allow 24 hours before a single test reset.
- Step 4 – Test on non-GFCI (diagnostic only): Briefly test on a non-GFCI circuit (qualified persons only). If it still trips the breaker or shows faults, internal leakage is likely.
Persistent GFCI tripping indicates unsafe leakage current. Replace the Tweeny disposal and correct any plumbing leaks.
