Commercial Disposers TROUBLESHOOTING DANGER Disconnect power before troubleshoot- If the problem is electrical: ing or servicing the disposer. • Troubleshooting problems other than those listed in this section should be performed by qualified service personnel. Any troubleshooting performed by untrained personnel could result in electrical shock or damage to the disposer.
Commercial Disposers Problem Motor hums but does not run; water runs. Cause Solution Jammed rotating shredder. See previous “Jammed rotating shredder” solution. Stator/lower end frame/upper end bell misaligned (thru bolts loose, bent, or broken. Remove and realign sections. Ensure thru bolts are not bent or broken. Replace bolts if necessary. Rotor shaft binding against stator core.
Commercial Disposers Problem Cause Overload protector is tripped or fuse/ Direct short in stator windings. circuit breaker blows immediately after starting disposer. Incorrect wiring connections. Disposer motor runs but little or no water runs. Water in stator. Solution Test stator windings and replace stator if open. See “Stator” on page 20. See applicable wiring diagram in installation manual. Start switch wired incorrectly. See applicable wiring diagram and correct connections.
Commercial Disposers Problem Water leaks from grind chamber area. Cause Stationary shredder gasket faulty. Solution Replace gasket. See “Replacing Shredder Gasket” on page 10. Water inlet connection loose in body. Replace water inlet connection. See “Cold Water Flow & Drain Line Diameter” on page 3. Water leaks from siphon breaker. Water does not drain or drains slowly. Bottom cover loose or damaged. Tighten or replace cover. See “Bottom Cover and Fan” on page 18. Stationary shredder damaged.
Commercial Disposers Problem Cause Solution Grinding elements worn excessively. Disposer undersized for application. Replace disposer with correct size. See “Serial Number Date Code” on page 2. Large amounts of highly abrasive material ground regularly. Replace rotating shredder and/or stationary shredder. See “Replacing Stationary Shredder” on page 11 and “Replacing Rotating Shredder” on page 12. Do not grind abrasive material such as glass, crockery, ceramic, or clam shells.
