What to Check When Your Dishwasher is Leaking


Have you come to unload your dishwasher only to find a puddle of water sitting in front of it? It might not be a huge puddle, but even a small amount of water inexplicably appearing in front of your appliance is cause for concern. Not only is it a potential slip hazard, but standing water will do damage to flooring and nearby cabinetry over time as well as invite mold to grow. You need to be able to quickly deduce what part of your dishwasher is leaking so you can get it fixed up quickly. If your dishwasher has developed a leak, these are all the parts you will want to check.

Check The Water Level

What most appliance owners don’t know is that only the very bottom of your dishwasher fills with water. The dishwasher itself is only watertight against splashing, so the water never fills past the door. However, if too much water is being pumped in, it will start to leak out the bottom. You can check this pretty easy by opening the dishwasher. If any water spills out, then it is overfilling.

This could be the indicator of a water inlet problem or a drain problem if you notice it happening later in the cycle. You may also want to consider testing the fill sensor for continuity to see if that is just shutting off the water too late.

Check the Inlet Hoses

This is a more complex problem to check as it may require you to remove your dishwasher from its alcove to check. However, if your water inlet hoses are leaking, it can be a serious problem that you are only just discovering. The issue is that the water can do a lot of damage before you see it leaking out front.

Once you have pulled your dishwasher out, you will want to check the inlet and drain hose to see if they are secure and not wet to the touch. Moisture without unthreading the hose can be a sure sign that the connection is leaking. You will also want to check the hose itself to make sure it is not cracked or brittle. An old hose can start leaking randomly but is really simple to replace in order to stop this issue.

Check the Water Inlet Valve

While checking the hoses for leaks, you will also want to consider that the water inlet valve, which is what the hoses are connected to, is the cause of the leak. Usually, with the hoses, you will be able to see cracks or a loose connection. So if you do not see any of those, it is more likely that the water inlet valve is malfunctioning.

Unfortunately, while all the above are really quite easy to do yourself, you will want to leave replacing the water inlet valve to a professional hand. It can be a complicated repair to do on your own and can have serious consequences if done incorrectly.
