IF THE GARBAGE DISPOSAL IS SPINNING AND SOUNDS NORMAL – First try a quick fix by cleaning out the disposer and the waste lines. The easiest is to run ice cubes in the garbage disposal. Fill the garbage disposal with the ice cubes and run the water. Then turn on the garbage disposal until the grinding stops. This should clear out the lines and water should drain from your sink. Another method is to run hard pasta in your disposal. Pour a bag of uncooked pasta in the disposal and run it while running the water. If neither of these simple procedures work, see below for more ways to repair it yourself.
IF THE GARBAGE DISPOSAL MAKES NO NOISE WHEN YOU TURN IT ON – First thing is to check the breaker in the house to make sure it did not trip. If the breaker is on then….. There is usually a red reset button on the very bottom of every garbage disposal (locate the disposal under your sink and find the reset button at the very bottom of the disposer itself). The reset button will stick out from the bottom of the disposal. Once located press the red reset button and test the disposal for proper operation.
IF THE GARBAGE DISPOSAL IS NOT SPINNING (HUMMING) – This means that the motor is not able to spin the disposer wheel. The first thing you should try is to insert an allen wrench (that came with your disposer) into the center of the bottom of the garbage disposal. While the wrench is in place, turn the wrench in a clockwise motion until it spins freely. If this test makes the disposer spin, then it is likely you have a bad motor on your disposal. If you do not have the allen wrench that came with your disposal, then you can use a wooden kitchen spoon. Unplug the disposal and put the end of the spoon into the sink hole and into the disposal. Try turning the wheel with the spoon. If this does not work then another method is to use a flashlight and look into the disposal and see if there is any large items that are preventing it from spinning. If you find something, remove it with a pair of tongs so to avoid putting your hand in the disposal.
IF THE GARBAGE DISPOSAL IS SPINNING BUT STILL NOT DRAINING – Then positively there is a major clog in the plumbing. See the pictures below to properly fix this. MAKE SURE TO UNPLUG THE DISPOSAL FIRST!
Step 8 – Once you are sure that all the clogs are removed, put the plumbing lines
back in their place and firmly tighten. Once everything is back together, run water
from the sink faucet and run your disposal. There should be no leaks, no clogs and the disposer should work.
