We don’t appreciate how handy having a dishwasher is until it starts having problems, like drainage issues that cause it to leak. Like most appliances, dishwashers require maintenance to keep it running smoothly. If your dishwasher is having plumbing problems, there could be a number of causes, including the following.
A Clogged Filter
The filter’s purpose is to trap food and debris that’s left behind after cleaning the dishes. If it isn’t regularly cleaned, the dishwasher gets clogged up, not only causing a leak but keeping dishes from being properly cleaned. If you notice that your dishes aren’t as sparkling clean as they used to be, it’s a good sign that the filter is clogged.
The Water Valve Leaks
If the dishwasher overflows, the cause could be the water inlet valve that passes water from the water line into the dishwasher. If defective, the valve can trigger drain pipe problems, causing the dishwasher to leak. This can also result in dishes not being cleaned appropriately.
A Defective Pump
The pump circulates the water in the dishwasher and drains it. A defective pump is one of the leading causes of dishwasher leaks and typically requires the help of a professional plumber. If the plumber finds visible signs of damage the pump will more than likely need to be replaced.
Leaking Door Seals
If water leaks are showing up in front of the dishwasher, chances are good that it’s not keeping its seal effectively. If this is the case, open the door of the dishwasher and check to see if the sealing around the door is worn, cracking or ripped.
A leaking dishwasher is a problem that is best fixed by a plumbing professional. Although there are some issues that you can do yourself, like cleaning the filter, most repairs should be performed by professionals to help guarantee the root of the problem is resolved.
