Hi, You need to punch out the plug from the outside. The plug will fall into the disposal and you can reach in to remove it.
I use a small screw driver and punch through the plug in a few spots to weaken the plug. This will allow the plug to release easier.
Please let me know if this helps you at all or if I can assist you further.

It fills with water and nothing happens

It can be disheartening to open your Whirlpool Gold dishwasher and find that the device is full of dirty water that has not drained from a previous cycle. Although you certainly would rather have no problems, having a problem with the washing machine not draining as well as it should is one of the easiest-remedied problems to have. Fixing this problem doesn't require you to pay a repairman; you should be able to do it yourself.
Open the cabinet under the sink.

  • 2 Unscrew the clamp that is holding the drain hose to the garbage disposal valve.
  • 3 Insert a screwdriver into the valve opening and tap the handle of the screwdriver with a hammer. Doing this will remove the knockout plug from the opening. The knockout plug is designed to be used for garbage disposals that are not connected to dishwashers. People often fail to remove the knockout plug when installing a dishwasher to the disposal.
  • 4 Insert tongs into the top of the garbage disposal opening and remove the knockout plug from the device.
  • 5 Replace the drain hose and screw the clamp back into place.

    How to remove knockout plug

    I am assuming you are removing it for a dishwasher hook up? Regardless put a punch, drift or worse case scenario a screwdriver through the inlet to the back of the plug and drift it with a hammer. Dont be afraid to hit it with a punch because it will require a hard enough hit

    Water is dripping out of the bottom of my kitchenaid kadette 250 1/2 HP disposal. Is there a fix?

    If the leak is coming from the bottom of the disposal check the sink connection, drain connection, and housing gasket. If you find these are all good and you can see the water is definitely coming from the disposal itself and not from any of these connections, then the internal seal in the disposal is bad and will need to be replaced. If the disposal is over a few years old then it is more than likely best to just replace the unit. Not cost effective to have it repaired.

    Water does not drain.

    If this is your 1st dishwasher and you have a garbage disposal installed, quite possibly the dw inlet fitting on the disposal still has the knockout in place. Remove the dw drain hose from the disposal and check to see if the knockout has been removed.

    Kitchenaid kadette 250 1/2 hp won't turn on.

    Try turning off the circuit breaker and turning it back on, pushing the reset button firmly on the bottom of the disposer, and checking to make sure it's not jammed and rotates freely. If it is jammed you can put a disposer wrench or allen wrench in the hole in the bottom and rotate the shaft to free it. There might already be a wrench under your sink for that.
