Where is the pressure switch in the washing machine?

Where is the pressure switch in the washing machine? Most modern automatic washing machines have a self-diagnosis function for emerging faults. And this is very convenient, since the user, having seen the error code on the display, can easily understand which element of the washing machine has failed and begin repairing it. If the machine has detected a breakdown of the 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 figure out where the pressure switch is located in automatic washing machines from different manufacturers.

Where can the level sensor be located?

Finding 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 free access to the installation site of the pressure switch, you need to turn off the power to the machine, disconnect it from the water supply and sewerage networks and move it forward a little. Then you need to unscrew the two bolts holding the top cover of the case and carefully remove it.

Owners of washing machines from such brands as Indesit, ElG, Ariston and Samsung will see a level sensor near the right side wall of the unit, in the corner, closer to the front of the machine. Stand facing the machine hatch, and you will definitely see where the pressure switch is located.
Owners of Whirlpool and Ardo brand models will also find the sensor near the right wall, closer to the rear corner.
Bosch washing machines are equipped with a large pressure switch, which is also located on the right wall of the unit, closer to its center. On some models, the level sensor is lowered down, and the user mistakenly believes that the machine does not have a pressure switch, but it is there, simply hidden from view by a beam and wiring.

To understand where the level sensor is located, find a thin rubber tube inside and track where it is directed.

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

What does this part look like?

what does a pressure switch look like? In order for the user to find the liquid level sensor in the washing machine, it is necessary to know what this element is. You can look at the pressure switch on the Internet; to do this, enter the query “Pressostat of an automatic machine” into the search bar. “Pictures” will contain about three thousand images of sensors of various models of washing machines, which are quite similar to each other.

The element that controls the water level in the tank is made in the shape of a small plastic circle. The power supply wires and tube are connected to the pressure switch. The entire structure is connected to a reservoir, which is under high pressure.

When water is drawn into the washing machine, pressure is pumped through the tube, which corresponds to the level of liquid collected in the tank. If there is enough water in the system, a special relay closes. Thus, the sensor transmits a signal to the control module and the flow of water through the inlet hose stops.

The level sensor is attached to the housing either with special latches or several self-tapping screws, so it is very easy to disconnect it from the wall. To remove the pressure switch, unfasten all the wires going to it and pull out the tube. After this, dismantle the part.

We hope this information will help you find and replace the pressure switch in a washing machine of any brand. The location of the liquid level sensor is chosen very well, and to find it, the user will have to make a minimum of effort.
