Dishwasher Not Draining: What Now?

This problem is not an overly common one that we see in the Markham plumbing business, but it does come up from time to time. You open up the door on your dishwasher and the bottom of it is filled with several inches of water. What do you do now? There are several things you can try if you feel comfortable before calling a certified Markham plumber.

First remove the bottom basket to allow access to the bottom of the appliance where the water is sitting. Now, look and feel for the drains along the bottom surface and make sure they are clear. Large pieces of food or even paper products sometimes get mistakenly put into the dishwasher if the dishes are not properly rinsed first and can cover the drains stopping the water flow.

If the drains feel clear, the next step is to attempt adding some liquid plumber or similar chemical drain cleaner to the dishwasher drains in an attempt to break up the clot that way. If that doesn’t resolve the problem, or you don’t feel comfortable using chemicals, you can attempt to remove the drain covers, which are usually held in place with just a couple of screws. After removing the covers you can try feeding a long flexible rod or plumber’s snake into the drain to attempt to manually break up the clog and restore the flow of water through the drain. As an alternative, if the bottom side of the appliance is accessible, you can remove the trap completely and clean it that way.

If none of these solutions solve your problem, or you simply don’t feel comfortable enough trying them yourself, then it’s time to call an expert Markham plumber. These experienced professionals can quickly diagnose and repair the cause of your problem and usually repair it in the same visit.
