Here’s Why Your Dishwasher is Leaking

Are you wondering why your dishwasher is leaking? You have just finished that dinner party you’ve been planning for weeks. Naturally, there is a stack of dishes to be done. In situations like this, that puddle under your dishwasher may worry or even stump you.

The dishwasher comes in handy every time. Therefore, it is best to keep it in the best conditions. This way, it can continue its honourable service. You definitely don’t want your dishwasher giving you extra housework to do.

A leak ranks among the most common of dishwasher problems. Therefore, it’s no surprise that puddles underneath your device may leave you wondering why your dishwasher is leaking. 

There are many causes of this dishwasher issue, often stemming from the defects in some individual parts of the machine. Here, you will learn about the possible causes of dishwasher leaks and quick fixes to get your device to a fine working state.

Is your dishwasher leaking? Here’s why

Here’s Why Your Dishwasher is Leaking

The main reason to ask why your dishwasher is leaking is pools of water under and around the unit. Aside from the unsightly mess, pooled water may lead to falls or create an electrical hazard. 

While you do not have a handyman’s skills, really, you don’t always need them. In fact, applying quick fixes to your dishwasher issues can be satisfying and rewarding.

Likely cause number #1 – the door

This is a no-brainer. If your dishwasher is leaking, particularly in the front or directly under the door, one of the first places to check is the door. 

Is it sealing well? Has it been compromised in any way due to age or wear? The first step is to check the dishwasher door gasket. 

The gasket, often made of vinyl or soft rubber, goes around the door, acting as a watertight seal. When such materials age, they become brittle. Essentially, they lose their ability to keep the water in, hence the leak. 

Replacing the gasket is easy, though. After purchasing a manufacturer-approved replacement, peel off the old one carefully, then wipe the exposed area. 

After softening up the new gasket, line it up carefully into position, without stretching it. Then close the door and allow the gasket to adhere appropriately to its position, creating the seal again.

Likely cause number #2 – the pump

The pump in a dishwasher circulates water throughout the tub. In some designs, the pump serves the added function of draining the water as well. Among the causes of dishwasher leaks, a defective pump or pump seal ranks high. While at home, carefully access the compartment in which the pump is. 

You can always observe the pump for any damage, which will mean replacement. If you happen to have a multimeter lying around, you can also use it. Evaluating the pump function can get a bit technical. So, if you are feeling unsure, be sure to call a professional dishwashing repair service.

Likely cause number #3 – the inlet valve

Another cause of your dishwasher leaking underneath is a defective water inlet valve. This piece connects to the central water supply system. Basically, it lets the water in. An inspection of this valve can point in the direction of the leak source. 

To access the valve, start by removing the lower panel in front of the dishwasher. This is also the point of entry to get to the pump. Examine the valve for signs of damage — cracks or wear. Any sign of damage is very likely why your dishwasher is leaking. 

At this point, only a replacement of the valve will work. When starting any such repairs, ensure to unplug the unit from electricity. It’s important!

Likely cause number #4 – uneven dishwasher

Another possible reason why your dishwasher is leaking is an unlevel placement of the unit. Ordinarily, a tilt of the dishwasher will lead to water sequestering on one side. 

This pooling of water in the dishwasher often creates enough pressure to force water seepage. If this is the case, you can easily correct the placement of an unlevel dishwasher. 

Readjust the machine and ensure it is straight. You can always use a level to ensure that you position it appropriately.

Likely cause number #5 – bad hoses, loose clamps

Typically, the pump has two functions, to circulate water through the machine and also to drain it out. To perform these functions, the pump is connected to some hoses. 

The water flows through the hoses across the dishwasher, emptying in the tub and an outlet. Furthermore, these hoses are usually made of rubber and can crack and leak after prolonged use. 

The clamps are little metal objects that tighten the hoses to the pump, creating a seal. These too may get loose and fail to hold the hose tightly, also causing a leak. 

The best you can do in this case is to find replacement hoses and clamps. To prevent those pesky leaks from returning, it is crucial to find one that perfectly fits your dishwasher model.

Likely cause number #6 – Corrosive detergents 

The tub of the unit may well be the source of the leaks. With prolonged use of the appliance, it is expected that the metal starts getting worn. If this happens to a great extent, it can leave holes at the bottom of the machine. 

Contributing significantly to this is if the detergents you use are not entirely supportive. Some detergents are not very friendly and can also lead to holes at the base of the dishwasher. 

How to fix a leaking dishwasher in this case? Well, sometimes it is possible. But it’s more likely you’ll need to totally replace the entire device.
