There’s really only one thing you want to see from your dishwasher - lovely clean kitchenware sparkling with freshness. If it should ever decide to give you the gift of puddles of soapy water slowly spreading across the kitchen floor, you might have a thing or two to say about it. You want it to do the washing up, not act as some sort of indoor water feature, so what can you do to stem the tide and work out what’s causing the leak?

The Knowhow

There are many things that can cause your machine to leak - it’s possible to fix a number safely yourself without the cost of calling someone to repair it.

Before attempting any checks, make sure the power to the machine is off and any liquid has been cleaned up to avoid shocks and slips.

Is the dishwasher level?

If you’ve recently installed or moved the dishwasher, make sure it is completely level and stable. If it is slightly tilted, or unstable on its mounts, water can leak from the front of the machine.

Is the seal working?

Examine the seal or gasket that runs around the edge of the door and frame. Are there any places where it looks loose, torn or cracked? Does the seal allow the door to close and the latch to hold it shut? If it looks damaged or isn’t closing properly, it could need replacing. It’s also worth checking the hinges on the door to make sure they are properly aligned as this could affect the seal.

Are the hoses OK?

Examine the hoses that feed and drain water from the dishwasher. Is there water where they connect? If so, check the clamps to make sure they are not loose. Make sure the outlet pipe hasn’t become kinked, stopping the water escaping. Dry the hoses if they’re wet, then check for leaks along the lengths of both hoses either with your fingers or by slowly running tissue paper along them. If they reveal any moisture or leaks, the hoses may need replacing or repairing.

Is the dishwasher blocked up?

Over time your dishwasher will accumulate some debris in the drain filter under the bottom drawer. If, after a wash, you open the dishwasher and find there’s still water in then this may be clogged. You can scoop out the water with a cup or jug, and then empty the filter. If there is still some water in the hole left by the filter try sucking it up with a turkey baster or using a plunger to clear any hard-to-reach blockages.

Is your sink blocked?

Some dishwashers drain via the sink. If the U-bend is blocked, this can cause water to back up and leak from the hoses, pipe or connections. Unblocking the sink may solve the problem.

Are you using the right dishwashing soap?

It’s important to only use products designed for use in a dishwasher to clean with. Using something like washing-up liquid can produce far too many bubbles for the machine and cause leaks.

A little detective work can save you the expense of having to call someone out, or help them get straight to the root of the problem. You’ll be enjoying a dry kitchen floor again in no time.

Always refer to the manufacturer’s manual for specific details.
