What is a washing machine pressure float?

The pressure float is a sensor device of the washing machine , with the function of determining the appropriate water level for the amount of clothes the user needs to wash. The device is directly connected to the circuit board of the machine.

Float has a 3-pin structure , of which 2 pins are connected to the mobile steel core coil , the other leg is connected to 2 capacitors . These two capacitors are connected in reverse to the 2 pins connected to the steel core coil first.

The washing machine float operates through a plastic air-filled hose that is connected from the switch to the bottom of the washing machine’s cage. When the water rises, the float will push out all the air in the tube and increase the pressure in the cage. When the set pressure reaches a certain level, the pressure switch will be turned on.

Normally, just turn on the switch, the washing machine will rotate many times before performing the water supply. This is when the washing machine needs the weight of the clothes, calculate the amount of water supplied accordingly. If within the specified time, there is no water supply, the system will recognize and display an error message on the screen of the washing machine.

How to check if the pressure float of the washing machine is broken?

Step 1: Adjust the meter and Ohm scale x1

Step 2: Take 2 rods of the meter, 1 stick attached to the middle pole , and one stick attached to the right pole of the pressure float

Step 3: Observe the indicator displayed on the meter

• Case 1: The indicator wo n’t display the value , or only shows one value , or the infinity value . That means your pressure float is broken.
• Case 2: The float shows full values equivalent to 0 Ohm , then it proves that the float is still good.

If the float test is still good, then you will proceed to check to see if the switch is damaged or not. Check the switch as well as the float. You attach to the 2 outermost poles and then observe the indicator on the clock. If the value displayed on the display is 0 then the switch has failed. If the display shows an infinity value, the switch is normal.
