Dishwashers typically do an excellent job of draining water. They have to in order to do their job well; having sitting water in a dishwasher can contaminate dishes and utensils, after all. But what if you've noticed that water seems to be coming up in your dishwasher? If you're having this problem, here's what you should do.
Why It Happens
This problem usually happens because there's a blockage somewhere in your plumbing. Some plumbing devices share pipes. For example, your dishwasher and your sink likely share a drain pipe. When a partial blockage develops, it can prevent your dishwasher from draining fully, or it can cause something to come back up that was draining from somewhere else. This is usually due to a high-pressure device draining, like a washing machine.
What to Do Before Calling For Help
There are two things you should do before calling for help from a plumber.
The first is to stop using your dishwasher immediately. Until the water is no longer pooling in the dishwasher, it's likely unsafe to run dishes in it and certainly unsafe to store clean dishes in it. Switch to washing them by hand for the time being, or at the very least, only use the upper dishwasher rack that's out of range of any pooling water.
Next, consider when your dishwasher develops standing water. Does it happen after you've run the laundry or washed a lot of dishes in the sink? Make a note of this whenever it happens so that you can let your plumber know. This will help to expedite the fix.
Now that you've tackled the problem at hand, it's time to seek help. A plumber can typically resolve this problem very quickly for you.
To start, a plumber will come out and will evaluate if any of your drains are running slowly, as this can tip them off to where the blockage might be. If none are, they'll run a camera down the drain to look for problems. If any are discovered, hydro jetting or a non-toxic drain cleaner will be used to clear the blockage and to ensure that your dishwasher is safe.
Once the blockage is out of the way, you should experience an immediate end to water pooling in the bottom of your dishwasher. You should consider asking your plumber about the best way to clean your particular brand of dishwasher, as there could still be germs or other dangerous debris that's come up from the drain inside the dishwasher that should be handled before using it again.
