Where is the pressure switch in a washing machine?

Most modern washing machines have a self-diagnosis function for detecting malfunctions. This is very convenient, as the user, upon seeing the error code on the display, can easily identify which component is faulty and begin repairs. If the machine detects a faulty pressure switch, then to replace the faulty part, you need to know what it looks like and where it is located in the system. Let's look at the location of the pressure switch in washing machines from different manufacturers.

Where can the level sensor be located?

Locating the liquid level sensor in a washing machine is quite simple. In most cases, it is located directly under the top cover of the machine. To gain easy access to the pressure switch, turn off the power to the machine, disconnect it from the water supply and sewer, and move it forward slightly. Then, unscrew the two bolts holding the top cover in place and carefully remove it.

1. Owners of washing machines from brands like Indesit, LG, Ariston, and Samsung will find the water level sensor near the right side wall of the machine, in the corner, closer to the front. Stand facing the door of the machine, and you'll definitely see the pressure switch.
   
2. Owners of Whirlpool and Ardo models will also find the sensor near the right wall, closer to the rear corner.
   
3. Bosch washing machines are equipped with a large pressure switch, also located on the right side of the machine, closer to its center. On some models, the level sensor is positioned downwards, leading users to mistakenly assume the machine doesn't have a pressure switch. In fact, it does exist, simply hidden by a beam and wiring.
   

To find out where the level sensor is, find the thin rubber tube inside and follow its direction.

If you cannot find the pressure switch on the right wall, look for the part on the top of the housing. Manufacturers very rarely place the level sensor at the bottom, as this significantly complicates the design of the unit. The pressure switch can be placed in the tray only on very old washing machines with a vertical loading type.

What does this part look like?

To find the liquid level sensor in a washing machine, you need to know what this component actually is. You can look up the pressure switch online by searching for "pressure switch for automatic washing machine." The "Images" section will contain about three thousand images of sensors from various washing machine models, all of which are quite similar.

The water level control element in the tank is shaped like a small plastic circle. Power wires and a tube are connected to the pressure switch. The entire assembly is connected to a reservoir, which is under high pressure.

When the washing machine fills with water, pressure builds up through the hose, corresponding to the level of liquid in the tank. If there is sufficient water in the system, a special relay closes. This sensor transmits a signal to the control module, and water intake through the inlet hose is stopped.

The level sensor is attached to the housing either with special latches or several self-tapping screws, so it is very easy to detach it from the wall. To remove the pressure switch, unclip all the wires leading to it and pull out the tube. Then, disassemble the part..

We hope this information will help you locate and replace the pressure switch in any brand of washing machine. The location of the liquid level sensor is very convenient, and finding it requires minimal effort.
