Disposal runs but has very weak grinding performance; food remains largely intact and is not being broken down properly.

Safety First: Disconnect power before inspection. Never insert hands into the chamber.

• Step 1 – Inspect grind components: Use a flashlight to look at the shredder ring and impeller lugs. If the teeth are smooth and the impellers do not pivot, grinding efficiency will be reduced.
• Step 2 – Free stuck impellers: Use a wooden dowel to gently move each impeller back and forth to free corrosion. Do not hammer or pry aggressively.
• Step 3 – Clean buildup: Grind a mixture of ice cubes and a small amount of rock salt with cold water running to help remove scale and buildup from the grind components.
• Step 4 – Re-test performance: Try small amounts of soft food waste. If performance is still poor, the shredder ring and impellers are likely worn beyond service.
• Next step: Because these parts are integral to the grind chamber on AmazonCommercial units, replacement of the disposal is typically required to restore full performance.
