Re: dishwasher does not drain. the suport screws are
Thanks for using FixYa.
Dishwasher not draining properly or not draining at all issues can arise due
to different reasons. Usually, these issues are related to kinked hoses,
knocked out disposer unit (if connected with the dishwasher drain hose) &
clogged drain pump & filter.
Also note that dishwashers do not
drain completely after a finished cycle and this is normal. Dishwashers are
designed to leave some water in the unit to ensure that the heating element
doesn’t overheat. If you suddenly begin to experience a large amount of water
being retained in your dishwasher, you have a problem. Some of the most common
reasons include that the drain hose isn’t working properly, the drain pump
isn’t working correctly, or possibly there is a plumbing problem in your home’s
First check whether the drain is
not clogged or blocked and the line is not kinked. Check all the hoses for
blockages & also clean the air gap. Has the disposer been replaced
recently? If so, chances are the knockout is still in place. Simply remove the
drain hose from the disposer, and knock out the plug. If the disposer has not
been replaced, try removing the drain hose from the disposer and use a wet-dry
vacuum (prepared for water, of course) to **** any water (and hopefully anything
else) from the drain line. Then reconnect the hose, and test the unit. If you
have checked the air gap and the drain hose and can’t locate the problem, then
it is an issue with the drain pump of the dishwasher.
Please do accept the solution if the issue is resolved or
else revert for further assistance.

Is it a new install? If so check the drain inlet under the sink. There is a round plug in the drain ( if it's new ) where the dishwasher drain line connects to the pic pipe under your sink.( use screw driver to pop it inward don't worry it won't clog your drain )
If it's not a new install the drain pump may just be worn out. Or the butterfly valve above the pump may not be opening. Manually open this valve, using a screw driver while it's running spin the dial until it's in drain mode. You will see a solenoid that pops up and down connected to the butterfly. Use the screwdriver to push the valve lever open all the way. Usually downward. hope this helps.
Drainage problem of some sort is usually the cause. Could be blockage before your drain pump, in your drain pump, or in your drain hose. One possibility is that you just installed a garbage disposal and forgot to remove the "knock-out" plug for the dishwasher drain line. Another cause can be that you have not looped your dishwasher drainline under your sink and water from your sink is flowing back into you dishwasher. You must attach your dishwasher drain line under your sink so it is higher then your sink drain lines, creating a trap for your dishwasher. Your drain sump could be plugged, not letting the water get to your drain pump easily. This is caused by not getting loose or hard debris off your dishes before putting them in the unit. Also make sure your drain pump is getting the right voltage when it is supposed to.God bless you
Common cause of this issue is a partially blocked drain line. Disconnect the drain line and make sure the entire path is clear, including where it hooks into the sink drain or garbage disposal. Also make sure the screens at the bottom of the dishwasher are free of debris.
I would check to see if the dishwasher is syphoning the water out. This is caused by an improperly installed drain hose. Check to make sure that the drain hose goes about the level of the main drain. Sometimes dishwasher are installed with teh drain hose going into a crawl space, or into a drain below the dishwasher.
dishwasher is not draining quick enough.. inside the dishwasher on the bottom is a plastic screen that has 2 screws...remove the 2 screws....clean out inside there....usually theres broken glass, food and other debris....if that doesnt work..look under the kitchen sink follow the dishwasher drain line to the sink drain and make sure all lines are not clogged
Common cause of this problem is a partially blocked drain line. Disconnect drain line and make sure entire path is clear, including where it connects to the sink drain or garbage disposal. Also, make sure all screens and the drain area at the bottom of the dishwasher are completely clear.
Debris that may be interfering with the drain in the bottom of the dishwasher - especially if the unit has a soft disposal. You may have to remove the lower wash arm and housing cover.
Check the drain line and be sure it's clear to the sink drain spur and that there are no kinks or other obstructions
Check the check valve on the discharge from the dishwasher - even small obstructions can cause this valve to plug or jam -this usually requires removal of the front lower panel - look for the drain line connection to the dishwasher - the check valve is usually screwed into a housing. Be careful un-screwing it. You may need a shallow pan to drain water into when you remove the drain line and check valve if there is still water in the dishwasher
It also could be the pump, but check all of the above first.
Finally, it could be the circuit board, but you didn't indicate there were any other problems with the dishwasher other than the drain
