  • Step 1: Disconnect the Power Connection

Before doing any fixes with your disposal unit, please remember to disconnect the power cord. Never put your hand inside the garbage disposal. Not even when there is no power connection. The grinding blades can simply chop your hand like a vegetable. To avoid any kind of accidents be conscious and always remove the power cord before starting the work.

  • Step 2: Pour Water Inside the Unit

Usually, the cooking items contain oil and fat elements that get stuck inside a garbage disposal. Over time it can get hard and jam the blades. Besides that, starchy substances like rice, noodles, pasta, stringy vegetable particles, etc. get jammed inside the small areas.

A strong flow of boiling water can simply wash out these substances and make the jammed corners clean and clear. After pouring a good amount of hot water rest it for 5 minutes. Run the cold water now. It will take away all the remaining greasy water from your disposal. Try to run the disposal now. If still, the garbage disposal makes humming noise, you need to proceed to the further step.

If you still cannot turn the blades with the Allen Wrench and the garbage disposal makes humming noise then maybe something bigger is stuck inside the disposal unit. Proceed to the next step.
