Repairing A Leaking Dishwasher


A leaking dishwasher can be a real mess and it can really trash a floor, especially a wood floor. So it would be a great idea to pull your lower panel and check it every once in a while for water leaks! There can be a few different causes for a dishwasher to leak water, so I put together a small list of things you can check before calling out an appliance repairman.

  • The first thing to check for is, if there is sudsy water.

If the suds overflow a little you may not see the soap unless you interrupt the dishwashing cycle and open the door and check. But I have known customers who said suds have leaded out of the dishwasher while running. (I call that a Lucy moment)! And there could be a lot of suds depending on the circumstances.


The suds are always caused be the soap. Sometimes the wrong soap is used. Other times the way the soap reacts to the water changes so, you may need to use less soap or change soaps altogether. Either way the soap is always the problem.


If you find suds in your dishwasher there is a way to get rid of it really fast! Just put a couple tablespoons of cooking oil in the dishwasher and run it for a few minutes. That will cut the suds. Once the suds are gone simply cancel/drain to remove the water. I would then recommend running a short hot water cycle to rinse the dishwasher out.

  • Also check to see if the drain hose or water supply is leaking.

To do this you will need to pull the lower panel. If the drain hose is leaking you might have a loose clamp, if you do tighten it. You may also have to replace it if it has a hole in it. The same holds true with the water supply line. It may have need replacing depending on what you find. If you tighten the nut on the water line and it continues to leak, replace it. I like to use the stainless steel braded flexible water lines myself.
