Water Coming Into Dishwasher When Off – Dishwasher Fills With Water – How To Fix It





Question: Water leaks into dishwasher when OFF. My dishwasher cleans and goes through cycles perfectly. However, after I run a wash cycle and remove all the clean dishes, there is an issue with water in the bottom. When the dishwasher is not in use the bottom of it fills up with water. The water is slowly coming in and filling up the bottom of the dishwasher. I see a round hole with a tube sticking out on the left side about an inch from the bottom of the dishwasher. I have seen a few drops of water coming from the hole on the left. However, I checked carefully and noticed the water was coming up from the bottom of the dishwasher. First, what is the hole or tube on the bottom left on the inside of the dishwasher? Also, if I see water coming from the bottom of the dishwasher when it is turned off, what can cause my dishwasher to fill up with water? How do I get rid of the standing water in my dishwasher? Any help would be great.

Answer: The most common reason a dishwasher has water coming into it when off is:
The dishwasher drain hose is laying flat under the kitchen sink and therefore letting the drain water back into the dishwasher.
This could also be water from the sink going to the dishwasher. There is usually a check valve that goes from your sink to the dishwasher. This is to not allow the water from the sink to get into the dishwasher. This valve may be faulty.
This also may be because the impeller has become worn down from continued use and cannot seal the area which acts similar to a check valve therefore letting drain water back into the dishwasher.

NOTE: Some set-ups are different. You may have a sink with a type of vacuum breaker that comes up with the dishwasher drain hose and is on top of the kitchen sink. If you have this set-up, simply check that the drain hose is in place. Check to be sure the line has no blockage in it. Also check to be sure that the drain hose is not kinked and therefore causing the dishwasher to not drain as this will cause water collecting in bottom of your dishwasher.







To fix the issue of my dishwasher (backfilling) fills with water when it is not running:

Attach the dishwasher drain hose with a zip-tie or similar up higher (attaching it onto something up behind the sink such as a small wood screw if needed) so no water can backflow into the drain hose and into the dishwasher. This is simply a gravity/siphoning issue. Basically, the drain hose needs to be elevated to stop the backflow of water.

Another thing to check with the dishwasher drain hose is to make sure it is not kinked, clogged or blocked. If it is kinked or clogged the water that needs to drain out of the dishwasher will not be able to fully drain because of the blockage. See image below to understand how the dishwasher drain hose should be positioned…

To answer your question about what is the small tube or hole on the inside left of the dishwasher:
The small hole you see in the dishwasher on the left side towards the back of the dishwasher is the WATER FILL INLET.
Basically this is where the Cold/Warm/Hot water comes into your dishwasher when running a wash cycle.
If you see a few drips coming out of it, this most likely is just residue water and is not the cause of the leak.
If you see water coming out of it when the dishwasher is not ON, then you have an issue with the water inlet valve.

NOTE: If you find out that it is FRESH WATER leaking into the dishwasher and not DRAIN WATER, then you may have a faulty WATER INLET VALVE or a bad IMPELLER. If you did have fresh water leaking in and you removed and replaced the water inlet valve, checked all the wiring and wire harnesses to be sure they are not damaged and securely connected. The next part to remove and replace would be the main control board. Be sure to thoroughly test all parts before replacing them. The parts you MAY need to replace on your dishwasher are below…
