In this guide manual we will go over the three basic problems that can go wrong with an Insinkerator 444 garbage disposal, and the troubleshooting method for each issue.

How to unclog an Insinkerator 444 Garbage Disposal.

If the disposal is working, but the water and waste wont go down, you have a clogged disposal chamber, or a clogged disposer drain pipe. The first step is to use a plunger. 9 times out of 10, the plunger will do the trick. Fill the garbage disposal up until water starts to fill the kitchen sink. Then with the plunger firmly sealed at the mouth of the disposal, pump it up and down several times until you feel a suction building, and then yank the plunger up and hopefully dislodge the clogged particles. If this doesnt work, then you will have to remove the drain pipe exiting the side of the disposal and clean it out with a screwdriver or something long and skinny.

DO NOT PUT YOUR HANDS INSIDE THE CHAMBER OF THE DISPOSAL…EVER!

How to unjam an Insinkerator 444.

allen key1 Insinkerator 444 Troubleshooting & Repair GuideIf your disposal is not working at all, or making a quiet buzzing noise when you turn it on, it is jammed. Use the Insinkerator 444 disposal unjamming key, or an allen key and insert it into the center bottom of the disposal and try to rotate it and free up the gears. Once it is rotating freely, push the red reset button at the bottom of the garbage disposal to reset the motor.

How to get rid of bad odors and sharpen the blades of your Insinkerator 444 garbage disposal.

If the disposer has a bad smell, or doesnt seem to grind the food particles up that well, you may a dirty disposal, or dull blades. No problem, just put a bunch of ice cubes in your disposal and turn it on. The hard ice cubes will grind into slush and as they do, they will sharpen the blades and wash all the gunk out of your disposal chamber.

Another trick for particularly bad smells is to run the disposal, turn the water on to a low-to-medium flow, and slowly dump in an entire box of baking soda.

If the disposal is leaking from the bottom, you will need to replace it with a new one as the chamber is probably rusted through.

    Brilliant ! My 444 wasn’t working. but all it wanted was the gears to be turned manually after getting stuck. So your advice (and an allen key) saved me at least $100 call out fee. Thanks !

    A breath of fresh air! My 444 wasnt working. I thought it might be the switch. I disconnected it and plugged it into another outlet and nothing happened. I thought I might have to replace it or call in a repair person. Checked online and Voila. Followed your instructions and all I had to do was depress the reset button on the bottom of the unit. Will try the ice cubes for smell and blade sharpening. How novel. Thanks :-)

    God Bless you Asheville Plumber! In these tough financial times, it’s so refreshing to see a very knowledgeable professional giving advice out of your good nature and saving much needed funds to cash strapped people. I didn’t know what else to try to fix my stuck InSinkErator 444-3. I followed your advice of using an Allen wrench, and that’s all it took to get it back to life. Reconnected the power, did the ice cleaning and the device is working perfectly. Thank you so very much for your efforts to post this advice. Somebody up here in the Midwest is very grateful to you.
    PS> If you add to the ice some spent baking soda (like the packages used to deodorize refrigerators), it will do a fine job of leaving the interior of your garbage disposal spotless, almost shinning! :)
    Thanks again for your advice.
