3 Reasons Why a Dishwasher is Not Draining and How Experts Can Help

Dishwashers are commonly seen in many households. They are also used for industrial purposes as they help save time, water, workforce, easy availability, and advanced technology.

Dishwashers can be some of the most common appliances to experience drainage issues. Many possible causes for a dishwasher are not draining correctly, from blocked filters to a broken pump.

This post will discuss why your dishwasher is not draining and how you can fix the problem yourself or call in the experts.


1. The Dishwasher’s Filters Are Clogged and Need to Be Cleaned

Some things which can block the dishwasher’s filters are pieces of food, grease, and soap scum. Over time, these things can build up and cause the dishwasher to have problems draining water. Cleaning the filters is a relatively simple process that can be done by following the manufacturer’s instructions.

If you notice that the dishwasher is not draining correctly, one of the first things you should check is the status of the filters.

If these blocks are not removed regularly, they can gradually build up and block water flow through the dishwasher. An expert plumber can clean the filters and unclog any drainage problems.

Cleaning the dishwasher’s filters is a simple process that can be done by following the manufacturer’s instructions. However, if your dishwasher is still not draining correctly, it may be time to call an expert.

2. The Dishwasher’s Pump Is Broken and Needs to Be Replaced

The pump helps move water from the dishwasher to the drain. If it is broken, water will not be able to move correctly and will cause your dishwasher not to drain. Fortunately, a professional can replace the pump quite easily.

Experts use a few different methods to clear drains.

They may use a manual snake, a long, flexible rod inserted into the drain to break up the clog physically.

If that doesn’t work, they’ll likely use a power drill. This machine uses a motor to spin a steel coil rapidly. The ring can break through the clog and clear the drain.

Sometimes, the drain may be too far gone for augers or snakes to be effective. In that case, your best bet is to call a professional plumber to handle the issue. They have specialized equipment that can reach deep into your drains and clear any blockages.

3. The Dishwasher Doesn’t Have Enough Water Pressure to Drain the Dishes Properly

You can check the water pressure in your home with a water pressure gauge. The water pressure in your dishwasher should be between 20 and 60 psi. If the water pressure is too low, the dishwasher won’t be able to drain correctly.

If the water pressure in your home is too low, you may need to have a plumber install a booster pump. A clogged inlet screen can also cause a dishwasher with insufficient water pressure. The inlet screen is located where the water hose attaches to the dishwasher.

Plumbers use a unique tool to clean the inlet screen. They have the experience and training to spot other potential problems causing your dishwasher not to drain correctly.


If you are dealing with a dishwasher not draining, plumbers can help. They have the tools and experience necessary to quickly and efficiently resolve any dishwasher issues you may be having.
