How to Fix a Garbage Disposal

No matter whether you’re a full-time foodie or an occasional heater-upper, there’s nothing more frustrating than garbage disposal that doesn’t work. When you’re accustomed to having convenient modes to get rid of scraps and clean out your dishes, it’s a priority to get fixed. 

Fortunately, we’ve compiled the ultimate guide to garbage disposal repair Detroit! In this guide, we’ll cover how to fix a garbage disposal—with or without professional help. Keep reading to learn the five most common problems, how to fix them, how to properly maintain disposals, and when to call in the professionals. 

Common Problem #1: Disposal Won’t Turn On

You flick the switch, and nothing happens. First things first, the most common issue: your garbage disposal won’t turn on. To troubleshoot, identify if the unit is actually getting power and check the outlet. If the outlet is working, the next step is to reset the disposal by hitting the red reset button on the bottom. It’s possible that it tripped, as a safety measure. 

Still no luck? Head to your circuit breaker panel and check if the switch controlling the disposal has flipped. If power isn’t the problem, examine the switch connections under the sink for any loose wiring. When you’ve tried all these steps and your disposal still won’t power up, especially if it’s over 10 years old, consider replacing the motor or the entire unit.

Common Problem #2: Humming But Not Grinding

Hearing a humming but no grinding? You’re likely dealing with a jam. Don’t worry, this is usually an easy DIY fix. Grab the Allen wrench that came with your unit, or one that fits the hex-shaped hole you’ll find on your disposal’s bottom. Insert the wrench and work it back and forth until you feel the blades move freely again. 

Once loosened, use tongs to carefully check for any foreign objects like utensils or tough food waste that caused the jam. To prevent future issues, always run water while using the disposal and avoid tossing in fibrous foods or hard materials.

Common Problem #3: Disposal Leaking

It’s never a good feeling when water starts dripping on your toes as you clean a full sink of dirty dishes. The first step here is to identify where the leak is coming from exactly. So, start by grabbing a flashlight and looking at these three main spots:

• The sink flange (that metal ring at the top)
• The dishwasher connection (if you have one) 
• The drain pipe 

If water’s seeping from the sink flange, you might need to replace the plumber’s putty seal—a quick and inexpensive fix. Leaks from connections usually just need a good tightening with a wrench. However, if you spot water from a crack in the disposal unit itself, unfortunately, there’s no reliable fix—it’s time to start shopping for a replacement.

Common Problem #4: Slow Draining or Clogging

The most frustrating common problem might be a slow drain or total clog. Is your disposal draining slower than a snail’s pace? This usually indicates that food particles have built up over time and have caused an issue. For instance, buildups such as coffee grounds, potato peels, and grease tend to trap everything else. 

To tackle the clog safely, start with natural solutions like baking soda and vinegar, followed by plenty of hot water. If that doesn’t do the trick, try using a plunger designated for sink use. To avoid these issues in the future, remember to run cold water before, during, and after using your disposal and only grind minimal amounts of food at a time. 

Common Problem #5: Strange Noises

If your disposal suddenly starts making strange noises, it’s telling you something. Here’s what each of the most common sounds is trying to say: 

• Grinding: A grinding metal sound usually means silverware or another metal object has fallen in; immediately turn off the disposal and fish it out with tongs.
• Rattling: Rattling noises typically indicate a loose component or trapped hard object, which you can often fix by tightening mounting screws or removing the offending item. 
• Squealing: That high-pitched squealing? It’s likely worn bearings in an aging unit, especially if it happens consistently during operation. While you can temporarily quiet squealing with a light lubricant, this sound usually signals your disposal is nearing retirement age.

Garbage Disposal Maintenance Tips to Know 

Keep your disposal running smoothly with regular maintenance. Once a week, freshen it up by grinding a handful of ice cubes with a cup of coarse salt; this helps clean and sharpen the blades. For a natural deodorizer, try grinding lemon peels or a mixture of baking soda and vinegar. 

While commercial cleaners work well, they’re not necessary for routine care. Remember what not to put down there: fibrous foods like celery and corn husks, hard items such as bones or fruit pits, and definitely no non-food items like glass, metal, or plastic. These simple habits will help your disposal last longer and prevent costly repairs.

How to Fix a Garbage Disposal: When to Call a Professional

For most common problems, there’s a DIY repair; however, more complex issues or replacements can require professional support. In general, serious issues such as: 

1. Electrical problems
2. Major leaks
3. Motor failure

Could benefit from the expertise and experience of a qualified plumbing professional.
