Common Signs the Garbage Disposal Needs to Be Repaired or Replaced

When to Call for Garbage Disposal Service

Clanking sounds or persistent foul odors often indicate problems within the garbage disposal system. These warning signs typically suggest the need for repair or replacement before the damage worsens. By identifying early symptoms, such as leaks, jams, and unusual noises, more costly issues and unexpected breakdowns can be avoided. The following guide highlights some of the most common indicators that garbage disposal repair or replacement is needed.

Strange Noises

sounds Garbage disposals should operate with a consistent sound. Unusual noises, however, are often a sign of internal problems that demand prompt attention.

Humming Without Grinding Action
A humming sound without active grinding typically means the unit is jammed. This occurs when objects, such as utensils, bones, or large food scraps, become lodged between the impeller blades and the grinding chamber. While the motor continues running, it is unable to turn the blades. Prolonged operation in this state may cause motor burnout within minutes.

Screeching and Metal-on-Metal Sounds
High-pitched screeching or metal-on-metal noises suggest bearing failure or damaged impellers scraping the interior walls. These issues reduce grinding performance and often indicate severe internal wear. Unlike minor jams, this level of damage usually requires professional repair or full replacement.

Rattling and Clattering Noises
Rattling sounds often result from loose mounting components or broken internal parts. Excessive vibration or shaking during use may indicate deteriorated motor mounts or dislodged hardware. According to the International Association of Certified Home Inspectors, units experiencing such vibration have a significantly increased failure rate within six months. Immediate inspection is recommended in these cases.

Leaks

leak Water pooling under the kitchen sink often indicates a leak in the disposal, which can lead to mold, cabinet damage, or other issues if left unaddressed. These leaks can come from several areas, including:

  • The mounting assembly at the sink connection
  • The discharge pipe leading to the drain
  • The unit’s bottom housing

Worn gaskets or deteriorated seals are the primary cause of most leaks. Moisture or water stains around the base of the disposal are early red flags. Once seals fail, water may damage internal electrical parts. According to HomeAdvisor’s 2023 appliance report, around 35% of disposal replacements are due to leak-related issues. While minor leaks can sometimes be repaired, replacement becomes more practical when multiple seals have failed or if the unit is old.

Bad Smells

Lingering foul odors are a common sign that the garbage disposal needs service, especially if the smell returns quickly after cleaning. These odors typically originate from trapped food debris lodged in hard-to-reach areas.

Simple cleaning methods, such as using ice cubes, baking soda, or citrus peels, can help eliminate surface odors. However, persistent smells often indicate internal damage, such as worn gaskets or compromised grinding components, that allow waste to collect in unintended areas.

According to the International Association of Certified Home Inspectors, nearly 30% of odor-related service calls are caused by internal mechanical problems rather than simple food buildup. If smells return within a few days of cleaning, this often indicates internal wear that requires professional attention. In such cases, complete replacement may be the most reliable and cost-effective solution.

How to Prevent Garbage Disposal Problems

Homeowners are looking for ways to reduce their workload between work, activities, and running kids to various places. One major convenience they use in the kitchen is the garbage disposal. 

This appliance can be a big help—until it stops working. A garbage disposal malfunction can quickly lead to foul odors and backups.

In this post, plumbers in Denton, TX, explain how households can avoid garbage disposal problems. These include watching what types of food are put down the drain, running cold water while using the system, and limiting how much food is placed in the unit at once. 

Foods You Should Never Put Down the Garbage Disposal

sinkOne of the most common reasons garbage disposals malfunction is because the wrong types of foods are put into the unit. This can wreck the blades and lead to clogs and other problems.

While various types of foods can cause issues, some of the worst types of foods to put down the disposal are fruit pits, bones, fibrous vegetables, and stringy foods. Soft food like coffee grounds, crushed eggshells, cooked pasta, fruit cores, grease, and oils should be avoided. These can cause coatings in the unit and lead to blockages.

Why You Should Run Cold Water Down the Garbage Disposal

sinkA simple way for homeowners to keep their garbage disposals functioning is to run cold water while the unit runs. 

While this is easy, it’s also essential. Running cold water while grinding food can prevent blockages from forming in the garbage disposal and the drain, resulting in a clean garbage disposal. It will also prevent the unit from overheating. If the system gets too hot while running, food scraps can bake onto the blades, damaging the system and leading to foul odors in the house.

Another simple task is to put ice cubes down the garbage disposal. This will dislodge any lingering food particles and help sharpen the blades. 

How to Limit the Amount of Food Down a Garbage Disposal

When homeowners are in a hurry, they can scrape the food leftovers and dispose of them in the garbage bin. This helps them clean the plates faster but can also cause too much food to go down the drain at once, leading to clogs.

To avoid this, homeowners must simultaneously limit how much food goes down the garbage disposal. They can cut larger pieces of food into smaller pieces to avoid blockages.

Homeowners should also look for signs that the garbage disposal is malfunctioning and needs to be repaired or replaced. Some key symptoms to watch for are slow drainage, loud garbage disposal humming noises, and a garbage disposal reset button that doesn’t work. When these occur, property owners need to call in the professionals!
