Blockages and Clogs

One of the most frequent reasons behind a non-draining garbage disposal is a blockage or clog because even with a strict cleaning routine, there are certain areas that you just can’t reach and that’s where food bits, grease, and other debris can build up, right in the disposal unit and the pipes, obstructing the flow of water. To tackle this problem, follow these steps:


a) Turn off the power: Before attempting to try anything to fix it, ensure the garbage disposal is disconnected from the power supply to avoid horrible accidents.

b) Use a hex wrench: Underneath the disposal unit, there is a small hole where you can insert an Allen wrench (hex wrench). Use it to manually rotate the disposal blades, loosening any trapped debris.

c) Flush with water: After using the hex wrench, run a stream of cold water down the disposal to help remove any remaining debris.

d) DIY cleaning solution: For a deeper clean, mix vinegar and baking soda and pour the solution down the disposal. Allow it to sit for a few minutes before flushing with hot water.

Jammed or Worn-Out Impellers

The impellers in your InSinkErator garbage disposal play an important role in shredding and disposing of food waste. If they become jammed or worn out, the disposal unit may struggle to drain correctly because the bits and pieces going through the pipes will end up being too big. Try these steps if you notice this issue:


a) Reset the disposal: Find the reset button that is usually located at the bottom of the unit and press it. This may help release any jammed impellers.

b) Check for visible damage: Inspect the impellers for visible signs of wear or damage. If you notice any issues, it’s best to call a professional plumber to replace them.

Faulty Dishwasher Connection

Many kitchen sinks have a dishwasher connection to the garbage disposal unit, allowing food particles from the dishwasher to be disposed of efficiently. But if your dishwasher connection is faulty or clogged, it could lead to improper draining and a near-future hassle with your dishwasher and sink. Try to do this before it’s too late:


a) Disconnect the dishwasher hose: Make sure to turn off the dishwasher first, and then carefully detach the hose connected to the disposal unit.

b) Clear any blockages: Check for built-up gunk inside the hose or the disposal unit’s connection port. Clean them thoroughly and reattach the hose securely.


Worn-Out or Clogged Drain Line

Sometimes, the problem isn’t even directly with the garbage disposal unit, instead, it stems from the drain line. Over time, drain lines can clog due to the accumulation of grease, soap residue, or other things. If this is the case, try to do this:


a) Use a plumber’s snake: Insert a plumber’s snake into the drain line to remove any clogs or obstructions.

b) Call us to try hydro jetting: If the clog persists, professional hydro jetting can effectively clear out stubborn blockages.
