Sink pop up waste won't close - KitchenAid Home

Have a look on u tube see if there is a video on it .

1. Waste Disposal/Sink trap
   • Empty your food waste disposal unit if your dishwasher's hooked up to one. If it's not empty, the old food inside it will back water up into your machine. Check that your sink trap isn't blocked by unscrewing it from the base of your sink if you don't have a food waste disposal unit. Make sure your dishwasher or any other appliances connected to it are not running when you do so.
     
   Incomplete Cycle
   • You may have opened your dishwasher's door mid-cycle before it's had a chance to drain. Check the progress indicator on your machine's control panel. The structure of this will differ depending on which Frigidaire model you're using, but it should show the point your machine has reached in its cycle. If this is the cause of the problem, close your dishwasher's door and let it finish.
     
   Drainage Pipe
   • Inspect the drain pipe that runs from your machine to your waste disposal unit or sink. If this is kinked or has been squashed under another appliance or a base unit, the waste water inside your dishwasher will be unable to escape. Check that water can flow through your waste pipe freely.
     
   Filter
   • Remove the bottom shelf from inside your machine and take out the plate covering the filter area. If you don't rinse your plates before you put them into your washer, food debris could block your filter and stop water from reaching your drainage pipe. You can unblock your filter with your fingers. Turn off your machine's power before you attempt to do so.
     

a vessel I dont beleive has a overflow. you need a differant waste for that unless theres something your not telling me

SILGRANIT II COORDINATED SINK WASTE DISPOSER STOPPER & STRAINER UNIT Fits disposer with 3-3/8" inside diameter only. It should just snap into the insinkerator sink flange.

either the check valve located in the lower sump is plugged or not closing fully and letting waste water back in,or the sump is plugged with waste food,or the drain line to the sink is partially plugged

I'm assuming this is a mechanical pop up drain. If so then one of three things are happening. Either the pop up mechanism needs to be adjusted, there is build up inside the drain where the stopper is or the mechanical parts are worn and need to be replaced.

Remove the items from underneath your vanity so that you have room to work. Under the vanity the pop up will have an adjustment rod. It is possible that the adjustment has slipped resulting in the drain not closing off properly. Try adjusting the connecting rod and see if that helps. If not move on to the next step.

You will need a small pail to catch any water when you disassemble the pop up. Inside the sink put something under the stopper to hold it in an open position because when you disassemble the pop up it will drop to the closed position and may be difficult to get out of the drain. Under the sink there will be rod coming out of the drain held on with a threaded nut. Unscrew the nut and the rod will come out of the drain and deattach from the pop up inside the drain. From the top of the sink remove the stopper. Clear any of the build up which is usually a distasteful combination of hair and soap scum. A pair of latex gloves come in handy at this point. Check the pop up for wear at the point where the rod attaches. It is possible that this could be worn to the point of not working correctly when the mechanics of the pop up are moved to the closed position. Your local hardware store will have any replacement parts required.

Be sure to reassemble every component before using the sink and test for leaks. Good luck with your project.

You need to get a one way valve fitted in the pipe just before it hits the main waste pipe. This will ensure that as soon as any backpressure is exerted that the valve closes and your sink etc will not fill with waste. This is a potential health hazard to you so I would suggest it is fitted ASAP.

I did not have a rubber plug, but removed the covers (sinked screws) and emptyd out the waste (aprox. 500 grams!).
apart from a fight with wife (I did it on the dinnertable) it did the job.

a waste with a over flow does not work well with a vessel sink because the sink is to thin

Look underneath the sink and you will find the lever that moves the drain up and down. It is probably stuck.
