To fix this problem, turn off the disposal, fill the sink halfway full with soapy water, and use a cup plunger to plunge the kitchen sink for 30 seconds to one minute. If you cleared the clog, the water in the sink should start draining at a normal pace again. If you’re still have issues, you might have to remove the P-trap under the sink to get at the clog with a snake.
Did exactly what I expected to. We bought a house with an older disposal and the gasket/rubber that blocks things from falling down into the disposal was cut away. I replaced and is like new. It makes the disposal sound much better too. A couple things about removing disposal and installing gasket...1) use a large Allen key (short end) to stick in the eyelet to unlock the disposal. 2) the gasket fits over the mouth of the disposal and locks into place. Don't just stick the new gasket in up from the bottom hole like I did. 3) use channel locks to tighten the last bit of the disposal/sink collar by pinching the eyelet and collar screw mount. Enjoy!
Hold a noncontact voltage detector against the wall switch with the switch in the on position. The presence of electricity at the switch causes the detector to beep and flash. Leave the switch in the on position and hold the detector against the outlet beneath the sink. If the detector does not sense the presence of electricity at the outlet, the switch may have failed and electricity can no longer reach the disposal motor. Have the wall switch replaced.
Plug the disposal and fill up the sink with hot water and detergent. Unplug and run the disposal. The spinning disk forces the water down the drain like a pump. This should clear the disposal and the drain line. If not, you'll need to inspect the plumbing. Old pipes made of iron clog easily due to internal corrosion and should be replaced with copper.
