Troubleshooting a Leaking Dishwasher

Once you move on from hand-washing dishes, there’s no going back. So when the dishwasher starts having problems, there’s no time to waste in getting to the bottom of it. You can always call us — and for some problems, you definitely should — but there are some small, common dishwasher problems that you can diagnose, if not repair, all on your own.

Finding and Fixing Leaks

Dishwashers are designed to not spill a drop, but leaks can develop if certain parts malfunction or become damaged. If you have an older dishwasher, some parts may be failing due to age and wear, which can also lead to leaks.

If you notice pooling water or signs of water spray around your dishwasher, it could be coming from one or more of three areas:

Around the door. The door is lined with a rubber gasket, much like the one on your refrigerator door. If there is a tear in the gasket, or if it has become cracked and brittle with age, this could be the source of your leak. At the water source. A hose or pipe carries water from your household plumbing to your dishwasher’s water inlet. If this connection is loose or if a gasket has failed, water could be leaking from this area.

Underneath the dishwasher. There are three places a leak can occur under here: the water inlet, the drain and the seal around the pump. Leaks in these places can be caused by loose or failed hose clamps, cracked gaskets or a broken pump. To get a good look around, you may need to clear out the area under your kitchen sink and remove the front kickplate of your dishwasher. Use a flashlight to look everywhere for the source of the water. If your dishwasher isn’t mounted to your countertop or cabinets, you may be able to scoot the dishwasher away from the wall to get a better look. Be careful not to snag or break any hoses if you do this.

If you’re lucky, you may be able to pin the source down to a loose connection — something you can fix in under a minute. If it’s a failed gasket or pump, check your dishwasher manufacturer’s website for information on replacement parts and DIY repairs. You may find the instructions for these repairs surprisingly simple, and if it ends up being something you don’t want to handle yourself, give us a call to book an on-site appointment.
