What You Need To Know About Leaking Dishwashers

4/26/2022 (Permalink)

Both commercial and residential property owners may encounter leaking dishwashers at some point. Before the issue can be resolved by SERVPRO technicians, you’ll need to unplug it then deactivate its circuit breaker. Additionally, be sure your watered supply valve has been closed, which can usually be located beneath your kitchen sink. Below are some common reasons dishwashers leak.

The Connections Are Damaged or Loose

Dishwashers are made with hoses, valves, and connections that are vulnerable to becoming loose or damaged as time passes. If you notice that the valves or hoses have become cracked or defective, they will need to be replaced, and it is important to ensure the clamps are of the proper size and have the strength needed to keep each hose in position even under pressure.

Your Float Switch Is No Longer Working

The float assembly is an important dishwasher component that uses a float switch and floats for the regulation of internal liquid levels during rinse and washes cycles. Once the dishwasher has completed its cycles, its float is supposed to lift up with rising liquid. After researching a specific height, it must trigger a float switch to deactivate the water. However, should the switch become faulty, its water level may become too high, resulting in leakage and mold. The solution to this problem is replacing the faulty float switch, but doing it yourself can be challenging.

The Dishwasher’s Door is Leaking

If you notice liquid pooling right beneath the dishwasher’s door, this could be a sign that the door itself is the source of the leak. Its latch might be loose or bent, which is preventing it from functioning normally. A screwdriver can be used for tightening the latch and allowing the door to close completely. In extreme cases, it might become necessary to buy and then install a brand new latch unit. If the gasket is damaged, it will have to be replaced, but the replacement should be soaked in warm and soapy water first so that it has greater flexibility and is simpler to manipulate when installing.

You’re Using Incorrect Detergent

This is a common mistake made by those who are not familiar with dishwashers. Standard soap will foam up excessively and because many dishwashers can’t handle it, leaks are the inevitable result. The solution to this problem is to review the dish soap you’re currently using and make sure it is compatible with your dishwasher. If you aren’t sure, read the manual that came with the machine and if you’ve lost it you can probably find a digital version online at the manufacturer’s website.

Your Dishwasher’s Spray Arm Has Malfunctioned

The dishwasher’s spray arm will spin during rinse and wash cycles, spraying the water onto the contents inside. However, if the dishwasher is improperly loaded or overcrowded, the dishes and utensils might block its arm, which won’t be able to correctly rotate since it’s become damaged or dislodged resulting in leakage. If this is the case you’ll probably have to buy and install a brand new spray arm, which can be purchased online.
