How to Know When to Replace a Disposer

The type of waste matter processed can affect the service life of a disposer. Depending on use, disposers can last between five and 25 years. Here are five indications that it might be time to replace a disposer.

Foodservice operators should be aware of certain disposer issues that could indicate the system has reached the end of its service life.

Increased Grind Time: Blades wear out over time, especially when the foodservice operation seeks to process harder material in high volumes. Increased grinding time or frequent clogging may signify the blades need replacing or, for older units, that a new, higher horsepower disposer is necessary.

Motor Failure: Smoke or signs that the motor is working harder to grind waste are early signs of system failure. When a disposer's motor dies, this indicates that the system has reached the end of its service life.

Cracks: Normal wear and tear, chemicals and vibrations over time can cause cracks in the system. This is a definite sign that it is time to replace the disposer.

Unusual or Excess Noise: Unusual or excessive noise may be an indication that the cutting elements need replacing, but, depending on the type of unit, it may make more sense to replace the disposer.

Frequent Repairs: The cost of a disposer needs to be weighed against the cost of repairs to determine if it makes more sense to fix the problem or replace the unit.
