Waste King Disposal Making Rattling Noise: Fix

Why is My Waste King Garbage Disposal Making a Rattling Noise?

A rattling noise coming from your Waste King garbage disposal can be unsettling and may indicate an underlying issue. This guide will help you understand the common causes of this problem, provide step-by-step solutions, and suggest preventive measures to avoid future occurrences.

Common Causes

Several factors may contribute to a rattling noise in your Waste King garbage disposal. Some of the most common causes include:

• Loose Parts: Internal components like the impeller, splash guard, or mounting hardware might have come loose.
• Foreign Objects: Small items such as utensils, glass, or bone fragments could be trapped inside causing the rattling sound.
• Jammed Disposal: Food debris may have solidified and jammed the disposal’s flywheel, creating a rattling noise.
• Damaged Components: Worn-out or broken parts like the dishwasher inlet connection or motor mounts can also lead to rattling.

Step-by-Step Fix Instructions

Before starting any repairs, always remember to turn off the power switch at the circuit breaker or fuse box and never put your hands near the garbage disposal while the power is on.

1. Check for Obstructions

1. Turn off the power to the disposal unit at the circuit breaker or fuse box.
2. Using tongs, carefully remove any visible debris from the disposal area.
3. If you have a reset button on your disposal (usually located underneath), press it to attempt to reset the motor. If there’s no reset button, try resetting via the circuit breaker or fuse box.

2. Inspect for Loose Parts

1. With the power off, locate the mounting screws or hardware underneath the sink.
2. Tighten any loose components with a screwdriver.
3. Ensure that the splash guard and dishwasher connection are securely fastened.

3. Address a Jammed Disposal

1. Turn on the cold water faucet to provide lubrication and help dislodge any jams.
2. Reset the garbage disposal as mentioned in step 2.
3. If the disposal still won’t turn, use a disposal wrench (also known as an “Octopus” or hex wrench) to manually rotate the flywheel located underneath. Turn it clockwise until you feel resistance, then counterclockwise until it spins freely.

When to Call a Professional

If the rattling noise persists after trying the above steps or if you notice any of these signs, it’s best to call a professional plumber:

• Unusual smells coming from under the sink.
• Leaks around the disposal unit.
• Frequent jams or failure to reset.
• Visible damage to the disposal components.

Prevention Tips

To avoid future rattling noises and other potential issues, follow these prevention tips:

1. Avoid putting non-food items in the disposal, like bones, fibrous vegetables, or grease.
2. Run cold water while operating the disposal to aid grinding and prevent overheating.
3. Regularly clean the disposal by grinding ice cubes with citrus peels to freshen and sharpen the blades.
4. Check for leaks periodically and ensure all connections are secure.
