While these appliances are extremely helpful to get rid of the food waste, they also come with a fair share of problems.

1. Jamming

Since the food is trimmed in smaller pieces to run through the drainage, it is not unusual for it to jam the pipes. You can fix that easily. Simply listen to the hum which will tell if something has got struck in the impellers and shredding ring.

You should disconnect the appliance from the power supply and take an offset wrench to spin it clockwise and anticlockwise to dislodge jam.

If the top flange is causing the problem, you can remove the disposal by turning it clockwise from the bottom.

At the same time, if the mounting bolts are the culprit then you should replace the plumber’s putty with a new one and add a silicon caulk instead. Always check the disposal unit for leakage again before turning it on.

3. No Power

These are electrically powered appliances. To use them, you have to make sure uninterrupted supply of power. Or else, it will not work. If at some point you find your appliance not working then don’t forget to reset it.

5. No Working of Disposal Blades

If the disposal blades go fritz in you then start by checking the flywheels. While doing this, make sure that the disposal unit is turned off.

Then locate the hex hole of the machine and using a wrench, detach it. Look for the debris in the impellers. Clean it and put it to work. If required, you should also sharpen the blades to avoid future clogging.
