If you own a washing machine, chances are you have noticed a tiny, quiet pump that runs in the back of the machine. You may have wondered:
How does it work? What does it do? And what does it pump?
This is not a washing machine repair manual. But we will tell you exactly what this pump does and show you some easy ways to troubleshoot any problems you might run into.

Digging further about washing machine pumps
When your washing machine stops pumping water into the tub, the first thing that you should do is check the settings. If they aren’t set correctly, that could be the problem.
But even if the settings are correct, it may be time to change your machine.
While most washing machines work pretty well, there are some problems that can happen from time to time. And one of the most common issues that people have with their washing machines is a pump problem.
In this post, I will go over some of the possible causes of a washing machine pump problem, and how to fix them.
How Does a Washing Machine Pump Work?
The idea behind a washing machine is pretty simple. You put in the clothes, start the machine, and then wait for it to finish. The machine pulls water through the system and uses it to wash the clothes.
But there are a few different ways that the water gets pulled through the machine.
The most common way to pull water into the washing machine is through a system of hoses. A hose has two ends: an inlet and an outlet. The hose is connected to the inlet of the washing machine, and the outlet is connected to a sink or tub.
When you turn on your machine, water will flow through the hose, down to the inlet, through the machine, and out to the tub.
There are two different types of pumps used in washing machines. They are an impeller pump and a piston pump. The different types of pumps have different names because they use a different type of mechanism. But what they all have in common is that they move the water around inside the system.
Impeller Pumps
An impeller pump works by having a rotating shaft with blades attached to it. These blades create an eddy current that pushes the water through the system.
This is the type of pump that is found in most modern washing machines. But when a washing machine stops working properly, it may be because of one of two things.
The first thing is that the impeller could be damaged. This could happen if the washing machine is broken, or if there is a blockage in the drain.
If the impeller is damaged, it won’t work as well as it should. It will also leave water behind in the hose. If this happens, you will have to remove the hose from the inlet and the outlet, and replace it with a new hose.
Piston Pumps
A piston pump works by having a rod with a piston attached to it. This piston has a number of chambers on it, and as the water passes through them, they push against each other and create pressure.
This type of pump is used in older washing machines. Because they don’t use an impeller, they don’t create an eddy current that helps move the water. Instead, the water is pushed around by the action of the piston.
Piston pumps are less likely to leave water behind. But if there is water in the hose, it can be hard to get out of a piston pump. You will need to either shut off the machine, or remove the hose.
