Датчик уровня воды в стиральной машинке, машинка набирает мало воды. прессостат стиралки

The pressure switch (water level) sensor has a bolt in the center. When screwed in (turned clockwise), the water level in the washing machine rises; when unscrewed, it falls. Slightly to the left is the overflow bolt. When screwed in, the overflow level rises; when unscrewed, the overflow level decreases (this can cause a program malfunction if it's too loose). The farther bolt is the delta bolt (this changes the water drop during filling and starting a wash cycle). When screwed in, the delta will change and become larger (if it's too loose, the sensor may stop working completely).
