How to Fix / Troubleshooting

Safety first: Turn OFF power before inspecting the chamber.

  • Step 1 – Inspect for structural damage: Look for holes, deep pitting, or loose rust flakes on the grind ring and chamber walls.
  • Step 2 – Avoid heavy use: Severely corroded components can fail and leak. Do not rely on the unit for heavy grinding.

  • Step 4 – Remove loose rust: Until replacement, briefly run the unit with ice to knock off loose rust, then flush thoroughly.
  • Step 5 – Check for leaks: Monitor the unit for any signs of leakage from the chamber or housing.
