Your Dishwasher’s Door Is Leaking and Overflowing

Have you had your dishwasher on and noticed it leaking from the door or underneath? Here we describe and explain the potential causes of this problem to enable you to solve it and, above all, avoid it happening again.

THE POSSIBLE CAUSES FOR THIS FAULT :

WARNING
Before you do anything to your appliance, make sure you disconnect it from the power supply.
There is a risk of electric shock.

Siphoning is occurring

Siphoning is occurring A siphoning phenomenon can occur during the draining process, causing the water to return to your appliance in the reverse direction and leading to your dishwasher overflowing. This is usually due to it being incorrectly plumbed in. To verify that your appliance is properly installed, check that the drain hose is at least 65 cm above the ground and inserted no more than 15 cm into the wall standpipe. There must always be enough space for the air to pass between your drain hose and your plumbing pipe.

The spray arms are damaged

The spray arms are damaged Your dishwasher's spray arms are made to rotate through the pressure of water. This rotation enables the water to spray over your crockery, cutlery, glasses and utensils, etc., during the washing programme. If these arms are damaged or blocked, the water could end up, for example, at the corners of the door, causing your appliance to leak.

There is too much rinse aid

There is too much rinse aid The rinse aid you put in your dishwasher speeds up the drying process. It enables any last remaining traces of food and dirt on your crockery, cutlery, glasses and utensils, etc., to slide off. As with any cleaning product, you should avoid using too large a quantity, especially if you live in a soft water area. Rinse aid produces a lot of foam, which can cause your dishwasher to overflow. We recommend wiping any excess rinse aid away when you load the appliance, which will prevent leaks from occurring.

The baskets are incorrectly positioned

The baskets are incorrectly positioned The baskets in which you place your crockery, cutlery, glasses, etc., are mounted on rails. The upper basket connects to the wash water circulation system by slotting into the back of the dishwasher. It's possible for it to be incorrectly positioned. If this is the case, the door of your appliance may not close properly, causing it to leak. You are particularly likely to encounter this problem if you've inserted the bottom basket the wrong way round (a common mistake).

The door seals are defective

The door seals are defective The seals both around and at the bottom of your dishwasher's door serve to ensure the appliance is watertight. If any of the seals are dirty, torn or displaced, a leak may occur. We recommend you attempt to put any such seals back in position and replace if necessary.

The drain pump is not working properly

The drain pump is not working properly The drain pump enables your dishwasher to evacuate the water inside it. If the drain pump is blocked or defective, it will not be able to evacuate the water. This may result in your appliance developing a leak. We recommend checking the drain pump and dismantling it to see whether there are any pieces of glass present, for example.

The pressure switch is damaged

The pressure switch is damaged The pressure switch controls the level of water in the appliance. If it is damaged and no longer functioning, your appliance may overflow. You can easily check the continuity of the pressure switch using a multimeter in ohmmeter mode.

The pressure chamber is blocked

The pressure chamber is blocked

The pressure chamber in your dishwasher enables the pressure switch to detect the water level. The switch then signals to the appliance that the correct level has been reached. Over time, the pressure chamber may become blocked. This will cause it to send an incorrect signal to the pressure switch, leading to a risk that the appliance will overflow. You can easily clean the chamber yourself. To do this, first disconnect the black tube leading to the pressure switch. Then, using a large syringe, or, if you don't have one available, taking some water in your mouth, squirt or blow very hard in the direction of the pressure chamber. By doing this, the water will cause the dirt, food remains, etc., to be pushed out. Once this stage is complete, empty the appliance and blow into the tube to dry it before then putting everything back in place and testing the appliance.

The programmer is not working correctly

The programmer is not working correctly Your dishwasher's programmer controls and operates the various wash cycles. The programmers on some older dishwashers use a timed filling system during certain cycles. If this gets stuck or jammed, it will lead to your dishwasher overflowing.
