Of all the common dishwasher problems, leaking all over the kitchen floor can be the most annoying issue. In this situation, there are three steps forward: try to fix it yourself, call a professional or replace the appliance. Many people skip to the third option without first trying the other two. Some problems that cause a leaky dishwasher are simple enough for a homeowner to easily fix. If these DIY fixes don't work, then it's probably time to call for professional help. First, let's see what a homeowner can do to troubleshoot and repair a leaky dishwasher:
Check the seal around the door
Dishwashers come with a seal that fits around the door called a gasket. This pliable plastic fitting seals the gap between the door and the dishwasher to prevent leaks. In some cases, food can stick to the gasket. The food or other debris makes it difficult for the gasket to seal, causing leaks. Cleaning the gasket is an easy first step. While cleaning, homeowners can also inspect for damage. A gasket with missing pieces of plastic may need to be replaced.
Clean the float switch
Found on the bottom of the dishwashing tub, the float switch shuts off the water when it reaches a certain point. If it is stuck for any reason, the dishwasher may not be adding the proper amount of water. The right amount of water affects the cleaning cycle, but it can also affect leaking. An overfilled dishwasher is more likely to leak. Consult the manufacturer's guide to locate the float switch. Once you've found it, make sure that it moves freely and is not stuck in place.
Check your detergent
A common cause of leaky dishwasher is an abundance of suds from handwashing detergents. These suds over-foam and squeeze through the gasket around the dishwasher door. It should be pretty obvious if this is your problem because there will be more suds than water escaping from the dishwasher.
These three steps are a good place to start troubleshooting a leaky dishwasher. However, if these steps don't resolve the problem, it may be time to call a repairman. Repairmen can tackle more complex problems, like a hose that isn't properly connected. They can also replace faulty float switches. Repairmen are trained to troubleshoot these and other problems with your dishwasher, so it's worth giving them a call if these steps don't resolve your leaky dishwasher issue.
