Pressostat in a washing machine: where is it located, how to replace the water level sensor yourself

Have you ever wondered how your washing machine determines when the water cycle should end? The water level sensor, also known as the pressure switch, is a small but essential component that holds the key to the solution. This gadget makes sure the washer fills with precisely the correct amount of water for every load, avoiding overflows and guaranteeing effective washing.

The pressure switch in your washing machine may be the problem if it isn’t filling properly or stops in the middle of the cycle. Fortunately, it’s not as difficult as you might think to replace this sensor yourself. You can get your machine back in working order and save money on repairs with a little guidance.

This guide will walk you through the process of replacing the pressure switch in your washing machine and show you where to look for it. Whether you’re an experienced do-it-yourselfer or this is your first repair, this simple method will have your washing machine operating efficiently once more in no time.

What is a pressure switch in a washing machine

Any brand of the device (including Samsung, Ariston, Zanussi, Electrolux, and others) has this part. A pressure switch controls the amount of water poured into the washing machine’s tank. The device cannot determine precisely how much water needs to be poured into the drum or if any water needs to be poured at all in the absence of a pressure switch.

The sensor resembles a tiny, rounded piece of plastic with wires attached to it. The controller is connected to a tube that originates from the high-pressure tank. The Candy or Electrolux washing machine’s sensor is activated when the water tank is filled, creating a rise in pressure that signals the opening or closing of the relay contacts. If the device is broken, it needs to be repaired and may even need to be replaced.

How the washing machine controls the water level

It is simple to comprehend how washing machines determine the amount of water poured into the tank once one is aware of what a pressure switch (controller) in a washing machine is and how it operates. Devices manufactured in the 1990s are equipped with antiquated mechanical sensors. Current iterations feature an electronic pressure switch. For instance, machines made by Samsung and Electrolux have long since transitioned to a more efficient relay. Additionally, the level sensor must be adjusted correctly.

What is an electronic pressure switch, and how does a new kind of washing machine’s water level sensor operate? For such an element, the principle of operation has not changed. The only differences are that it is now smaller and has more accuracy and dependability. Samsung computers come pre-installed with DN S14.

The water level is managed by the unit. The gadget notifies the controller to carry out the chosen washing mode based on the volume of water gathered in the tank. Occasionally, the liquid in the tank either stops collecting or does not emerge. You must be able to check the pressure switch in this situation. Additionally, you must understand how to modify the pressure switch.

Where is the pressure switch in the washing machine

You must disconnect the hose and turn off the power in order to inspect the washing machine’s water level sensor, also known as the pressure switch. Next, take off the case’s top section. The water level sensor is situated on one of the walls nearer the upper section of most contemporary models, such as the Ariston washing machine. The front wall of the Samsung, Indesit, and Electrolux washing machines houses the water level sensor and pressure switch, respectively.

Once you’ve reached the indicator, take it out of the hose. Using pliers, take out the clamp to accomplish this. Examining the tubes for damage and the relay contacts for contamination constitutes checking the washing machine’s pressure switch.

Adjusting the pressure switch

The pressure switch of the Siemens or DN S14 Samsung washing machine must first be adjusted by the manufacturer in order for it to react appropriately to the tank’s filling level. This usually suffices, and no additional adjustments are made to the machine’s water level sensor.

Sometimes the water in the tank is not completely drained or not enough is poured into it. You must learn how to inspect the washing machine’s water level sensor in order to resolve the issue. If the controller functions properly and there is no damage, the issue is most likely a misconfiguration of the factory settings.

Next, the domestic washer’s pressure switch can be independently adjusted. Special screws on the device must be tightened with regular pliers.

What are the signs and causes of pressure switch malfunctions

There are several indicators that indicate a malfunctioning control device:

• The machine stops filling the tank with water for washing or works with a tank without liquid;
• The cycle of water supply and drainage is repeated many times;
• The device does not perform the rinsing program, washing at the required level;
• After the completion of the working process, water remains in the tank.

You should read the instructions on how to inspect the pressure switch in your washing machine at home if any of the aforementioned symptoms develop. However, some of the symptoms might also point to issues with a different component. It’s critical to comprehend how to inspect sensor models such as L11X, SPSS 11, DNN S14, and others.

The following could be the root of the water level controller’s issues:

1. Depressurization of hoses, valves;
2. Clogging of the high-pressure tank;
3. Clogging of the pressure pipe with debris;
4. Burning of relay contacts.

The accumulation of dirt within the system is the most frequent reason for sensor failure. Poor quality water and overuse of powder can cause clogging. Contamination is frequently caused by threads and other laundry-related particles.

One of the most important parts of a washing machine that helps regulate the amount of water in the drum during a wash cycle is the pressure switch, also called the water level sensor. In the event that your machine is overflowing or does not have enough water, it may be necessary to replace the faulty pressure switch. This guide will help you locate the sensor in your washing machine and provide you easy-to-follow instructions on how to replace it so that your machine functions properly once more.

Hardware check of the sensor

It’s wise to perform a hardware check prior to fixing a domestic washing machine’s pressure switch. Get a multimeter and learn how to use it before you check the washing machine’s pressure switch on your own. Many owners of automatic washing machines are curious about how to check the washing machine’s press system with a multimeter.

The working algorithm for Bosch, Ariston, and Samsung models is below:

1. Prepare a device to check the resistance;
2. Place the probes of the multimeter on contacts that correspond to the electrical circuit of the relay;
3. Create the pressure in the air tube until the controller contacts a certain contact.

It will be necessary to replace the sensor if the contact has been made and the resistance value does not change. If the machine was found to be in good working order, you should inspect the tube’s sealing and attachment to the relay. It is important to handle the parts of the washing machine with the press neatly. Configuring the washing program is crucial at the same time.

Replacing the press -start

Should diagnostics reveal that the water level indicator is malfunctioning, the washing machine’s pressure switch is swapped out for a functional component. A broken Candy pressure switch is something you can easily repair at home with a new gadget.
