There are several potential causes of a leaking dishwasher. You do not need to spend money on a professional to repair your appliance. Instead, read on to learn how to diagnose the problem and take steps to fix it.

Problem #1: Loose Fittings

General use can cause hoses to come loose. When this happens you'll wind up with a leaking dishwasher. This is an easy problem to fix. Unscrew the service panel on front of the dishwasher, just below the door. Open the panel all the way if it is on hinges or remove it if on hooks.

Examine the hose connected to the dishwasher. If it is loose, it may be dripping water. Use the screwdriver to tighten the clamp holding it in place. Next, check the connection from the hose to the sink. Tighten the clamp with the screwdriver. Now, inspect the water-inlet valve. Tighten the compression fitting that connects the water supply to the valve

Check for leaking in the fill hose. If necessary, replace the spring clamp with the worm-drive hose clamp, and tighten it.

Problem #2: Dishwasher is Not Level

When a dishwasher is not level, the water will pool at one side during normal use. This will cause a leaking dishwasher scenario. To fix it, you need access to the adjustable feet. Remove the front access panel and open the door completely. Remove the lower dish rack. If the dishwasher is attached to the counter, unscrew it so that you can freely move it while you work.

Place the miniature level on each side of the dishwasher on the inside. This will tell you which sides are not even and what you need to fix.

Work from side to side and back to front. When you detect an uneven side, use the pliers to adjust the feet. Continue checking and adjusting until all sides are level. When you are finished,  screw the dishwasher back to the counter and replace or close the access panel.

Problem #3: Leaking Door

When the door gasket ages, it can crack and fail, causing a leaking dishwasher door. Examine the gasket in the door. If it appears solid, then the problem may be the door latch. Adjust it so that it makes a tight seal. If, however, the gasket is damaged, you can pull it from its groove with the pliers.

Place the replacement gasket in hot water so that it becomes pliable. Push the gasket into the groove, working around the part, starting at the top.
