Why is my Dishwasher Leaking?

The dishwasher in your home is an integral part of everyday life, we are sure you will agree.

If you have come to rely on your dishwasher, and find it a bit scary to imagine having to go back to hand-washing the dishes after meal times, the last thing you want is a dishwasher that has developed a leak isn't it?

If you have walked into your kitchen ready to unload the dishes, but are being confronted with a leaking dishwasher, there will be a handful of reasons that could possibly be causing this. Luckily most of these causes can be simple fixes.

Read on to help identify the fault, and with a little bit of patience, we can help you restore your dishwasher back to full working order without the leaks - so that water is no longer flooding your kitchen.

Cause 1

Lower Door Seal

Over time the lower door seal can perish and when this happens water can escape and find a new home all over your kitchen floor. When this occurs there are a number of checks which you can do to help identify whether the bottom seal on your dishwasher is damaged - and therefore is the reason for the leak. 

Safety First! Please make sure that you have disconnected the appliance from the mains before beginning any repair.

  • To find a fault with the seal, you will need to check the lower seal for any signs of damage as the seal may perish over time.
  • Dropping the door down allows access to the lower door seal, the door panel may have to come off to check the seal as it normally fits over the dishwasher cavity.

Hopefully, after following these simple steps, you have been able to identify the cause to your leaking dishwasher - leaving you to continue to clean those pots and pans with ease. However this may not help everyone, therefore don’t forget to check our additional advice articles.

If you followed the advised steps listed above, and have determined that it is the lower seal that's causing the problem, then it will need to be replaced. Don't worry if this is the case though, here at eSpares we have a wide range of replacement door seals as part of our offering of dishwasher spares.

Once you have a new seal, you’ll need to replace it! See our guide on how to do that and save yourself the cost of a call out.

Cause 2

Hoses

Here we will look at a common problem with dishwashers, a leak coming from a faulty hose.

The last thing you want to do with something designed to help you with the washing up is having to clean water from the floor. If you do have a leak then we can help identify which hose is leaking.

Safety First! Please make sure that you have disconnected the appliance from the mains before beginning any repair.

  • Inspect the external hoses for signs of wear or damage - these will be located at the rear of the dishwasher.
  • Examine the fill hose seal, which can be found at either end of the inlet hose, and if the rubber has perished in any way then the seal will no longer be effective enough to contain the water (resulting in a leak).
  • Don’t forget to check on the internal hoses! Over time these also may begin to perish, even tiny holes could be the primary cause to a leaking a dishwasher.

If you have gone through these checks and have found that it is indeed a damaged or faulty hose that is the cause of your water leak, then eSpares are here to help you solve the problem.

Cause 3

Upper Door Seal

There are two door seals (otherwise known as gaskets) inside your dishwasher, the more durable and difficult to replace is the lower seal - and there will also be a 3 sided upper seal. Both stop water from leaking on your kitchen floor and over time both can wear and perish.

The upper door seal is relevant for 3 of the 4 sides in the dishwasher cabinet and is more likely to wither than the lower seal. We have gathered some details of how to diagnose a faulty upper gasket below:

  • Condensation can be a main player, where water can be found on the floor at the front of the dishwasher. Steam can escape, condense and drip onto your floor if the seal is not doing its job. 
  • To find a fault with the seal, you will need to check the door itself will seal when it is closed.
  • Checking the gasket for any sign of damage is a must and can be achieved by dropping the door.
  • The inner section of the door will close against the seal if a gap appears this may result in a possible leak.

We hope that after you have performed the advised steps above, you have been able to locate the root of the leak. Do not worry if you have found an issue with the upper door seal and it now needs to be replaced - because we offer a wide selection of upper door seals as part of our extensive range of dishwasher spares.

Hopefully, after following these simple steps, you have been able to identify the cause to your leaking dishwasher. However this specific article may not help everyone, therefore don’t forget to check out our additional articles that are available.

Once you have obtained your new seal, you’ll need to replace it! See our guide and video on how to do that yourself -  saving you the cost of a call out.
