My Dishwasher Is Leaking

Dishwasher puddles can be a worrying sign. If your dishwasher leaks water after every cycle, there may be an issue with one of the internal parts.

Why Your Dishwasher is Standing in Water

Your dishwasher may be leaking for a number of reasons: a loose gasket or seal, a clogged spray arm, a faulty float switch, or from a damaged drain hose or valve. In any case, a few towels won’t stop water from collecting under your dishwasher – you’ll want to locate and fix the leak right away, before your kitchen turns into a swimming pool.

Potential Issues

The drain solenoid is what triggers the drain out to the dishwasher. It is working in connection with the pump motor. This part can leak in time and is needing replacement in order to fix the leak.

Water travels through your dishwasher through two main lines — one where the water comes in and one where the water comes out. The aptly-named water supply line connects from the main water supply to your dishwasher and feeds fresh water into the appliance. The second line is the waste line, which connects from the dishwasher to the garbage disposer (if you don't have one it connects to a dishwasher tailpiece under the kitchen sink). These two lines work together to whisk away food and grease, leaving your dishes sparkling while you go about your day. However, anywhere that two parts connect is prone to issues, and these lines are no exception. Wear and tear over time can break down the connections in the lines and cause a leak.

The dishwasher water supply line connects from the main water supply to your dishwasher. It's job is to feed fresh water into the appliance. Like most supply lines, the line is always under pressure to ensure that water can flow easily through the pipe as soon as you need it. However, this also means that the line is always filled with water, even when you're not running your dishwasher. This combination of water and pressure means that if any gaps, cracks, or holes open in the water supply line, it will start to drip, and it will keep dripping until the valve that leads to the water supply line is closed. This can lead to big puddles and even bigger headaches if you don't catch it quickly.

  • water under the dishwasher

Your dishwasher has two main lines. The first is the main water supply, where clean hot water comes into your dishwasher. The second is the drain line (also called the waste line), which is responsible for whisking all the food and grease from your dishes into the drain system and out of your life. The drain line connects from the dishwasher to the garbage disposer. If you don't have a garbage disposal system, the drain line will connect to a dishwasher tailpiece under the kitchen sink instead. The drain line only contains water when the dishwasher is running, so as long as your dishwasher is off, you won't have to worry about further leaks while you're waiting for a repair.
