How Does Dishwasher Drain Pump Work?

A dishwasher drain pump is an essential component of a dishwasher's operation. It is what transports the dirty water out of the machine to the drain and ultimately out of the house. Here is a step-by-step guide on how a dishwasher drain pump works:

Step 1: The Cycle Begins.

Once the dishwasher cycle begins, the dishwasher motor kicks into action and creates pressure in the water lines, pushing water into the dishwasher's tub. As the tub fills up with water, the dishes are subjected to high temperatures and cleaning agents.

Step 2: Water Circulation.

The water circulating pump takes over once the tub is fully loaded. It circulates the water all around the tub, ensuring that all the dishes are cleaned thoroughly. At the same time, water is drawn into the spray arms, which then rotate and distribute water all over the tub.

Step 3: Dirty Water is Collected.

As the water circulates, the dishwasher's drain collects the dirty water, which is directed to the drain filter. The drain filter is accessible from inside the dishwasher and is responsible for removing large particles such as food debris and other solids.

Step 4: The Drain Pump is Activated.

Once the dirty water has been collected into the drain filter, the dishwasher drain pump is activated. The pump starts to move the water out of the dishwasher through a hose that connects to the sink or garbage disposal.

Step 5: The Water is Pushed Out of the Dishwasher.

The pump continues to work until all the dirty water is removed from the dishwasher. The water is then pushed through the hose and out of the machine, leaving the dishes clean and ready to be dried.

Step 6: Clean Water is Added.

As the dirty water is pumped out, clean water is added to the dishwasher tub to rinse away any leftover soap and food debris. The circulating pump then starts circulating the clean water in the dishwasher tub.

Step 7: The Cycle Ends.

Once the clean water finishes rinsing the dishes, the dishwasher motor shuts off, and the drain pump stops working. The dishwasher cycle is now complete, and the tub is drained of all water.

Conclusion.

In summary, the dishwasher drain pump plays a significant role in the dishwasher's operation. It is responsible for moving dirty water out of the machine and making way for clean water to rinse the dishes. By following these simple steps, you can better understand how a dishwasher drain pump works and keep your dishwasher functioning correctly.
