Sometimes it becomes necessary to replace the pressure switch in the washing machine. The failure of the structural element is indicated by insufficient liquid flow into the tank or its excess. The device cannot function for a long time with such a malfunction. The corresponding error will appear on the display, and the equipment will stop working until the problem is completely eliminated. Self-repair is not difficult, especially if you know all the nuances of replacing the part and adhere to the sequence of actions.
The pressure switch looks like a "tablet". It is located under the top panel of the machine. A tube extends from the body of the element, which connects it to the tank. The more liquid the equipment collects, the higher the pressure in the hose. As a result, one of the contacts closes, and a signal is sent to turn off the water intake valve.
You can select a suitable pressure switch by its serial number and the model of the washing machine. The easiest way is to get the water level sensor and take it with you to the store, you need to show the part to the seller, and he will select the same or an alternative option. Failures in the water intake and drainage system indicate that the pressure sensor is out of order:
All the listed "symptoms" indicate a malfunction of the pressure switch. First, the element is dismantled. Then diagnostics and replacement are carried out with your own hands.
Replacement does not require many tools, just a short tube and a screwdriver. First of all, the washing machine must be disconnected from the power supply (the plug should be removed from the socket). Then the water supply valve is closed.
It is necessary to unscrew the bolts holding the top cover of the device. The panel is moved back and removed from the body part. The pressure sensor will be visible near the side wall. How to dismantle it?
After dismantling, you need to prepare a new working sensor and install it in place, fix it with bolts. Then connect the wires. Put the hose in place and secure it with clamps. Do not put the lid back in place yet. It is recommended to run a short wash cycle. If the water is collected and drained normally, you have successfully replaced the water level sensor.
When using a washing machine, it is worth periodically cleaning the inlet hose from accumulated debris and rust. For preventive purposes, it is better to install filters. This way, small particles coming from the water supply will not clog the parts of household appliances.
