Faulty spray arms can make the dishwasher door leak
If your dishwasher door is leaking, check the spray arms for not being clogged. They should also spin freely.
If the spray arms are clogged or broken, water can't be properly sprayed on the dishes and may leak out of the door gasket. The water level can also increase and leaks out.
It's so easy to unplug the spray arms. Take a needle and clean the holes out. Replace the spray arms, if they are broken.
Too much rinse aid may leak out of the dishwasher door
Rinse aid is used to speed up the drying process and make the dishes shiny. But if you use too much rinse aid especially when the water in your area is so soft, there will be a lot of foam that can leak out of the dishwasher door. So, pay attention to the dishwasher manual instructions and use sufficient amount of rinse aid, not less, not more.
Badly positioned baskets can cause the dishwasher door to leak
The dishwasher baskets in which you place the dishes, move on some rails. The upper basket is usually attached to the dishwasher water circulation system at the back. So if it is incorrectly positioned, the door won't close properly and water leaks out of the dishwasher door.
Note: pay attention to positioning the lower basket too. It's a common mistake to insert it the wrong way around.
The door gasket is used to ensure the appliance is completely watertight during the wash cycle. A dirty, torn or displaced gasket can cause the dishwasher door to leak. So, put it back in position or replace it if necessary to avoid any leaking.
Tip: If the new gasket is a so hard and can't be easily positioned, let it remain in warm soapy water for a while, then use it.
Note: the new gasket should be compatible with your dishwasher. Otherwise, it can't be a good seal to prevent leaking.
Faulty pressure switch a reason for dishwasher door leaking
The dishwasher pressure switch controls the water level inside the appliance. So, if it is defective, the dishwasher will be filled with too much water which may leak out of the door. Use an ohmmetre to check the pressure switch and replace it if necessary.
The dishwasher air gap can be blocked by food residue and debris. So the water flow will get restricted and it will leak out of the dishwasher door. It's so easy to solve this problem. Remove its metal cap and clean it. Check the tube attached to the gap for not being clogged too.
Tip: air gap is a small opening on the sink to prevent syphon effect.
Clogged drain line or filters can cause dishwasher door leaking
The drain line is under the dishwasher and filters are at the bottom inside the tub. They can be clogged by the food residue and bits of debris. So water can't go out anywhere and leaks out of the door. Just clean the line and the filters more often to solve and prevent this problem.
Note: you can use a solution of equal parts of baking soda and white vinegar to unclog the drain line. Let it sit for a while and then wash with hot water.
