Get matched with top garbage collectors in East Carbon, UT

No, you don’t need a garbage disposal for a dishwasher. A dishwasher will work without a garbage disposal. However, the two appliances pair well and are often installed together. It is rare to see a home with a dishwasher that doesn’t have a garbage disposal, but that doesn’t mean it's not possible. Each appliance serves its own purpose. 

There are many maintenance and repair issues that lead to a malfunctioning garbage disposal. Regular clogs place wear and tear on the motors, leading to an eventual shutdown. Electrical issues at the breaker, wall outlet, or disposal itself can fry the unit. The most common cause is simply a worn-down motor. These motors can only handle so much use before powering down for good. 

Garbage disposals last an average of seven years but can function well past 10 years. However, as time goes on and more food is ground, the grinding plates will slowly lose their edge and need replacing. A motor likely won’t last 10 or more years, but you should be able to get a minimum of five years at least, even under heavy usage. 

Garbage disposals can last between 10 and 12 years, so if your unit is pushing its lifespan, it may be a good idea to replace it. If your unit isn’t approaching the 10-year mark, try investigating other parts of the disposal to see if there's an affordable repair on the horizon. For example, rubber has a shorter lifespan than 10 years, connections and hoses loosen over time, and sink flanges can cause leaks that have nothing to do with disposals.
