On the problem of pressure sensors for fully automatic washing machines

Full automatic washing machine washing water total, check the Internet said pressure sensor is broken, buy new or the same problem, pull off the water inlet mouth pressure sensor has the sound of Da Da, is not working, a water bucket when the pipe did not see the water, do not know when this thing work is water the pressure to go up or go up, the water is changed, not what the blockage of the old washing machine, Little Swan, the two wires connecting the sensor connected to turn together washing machine, dehydration, motor clutch what should be no problem, for the home of the expert in this detail good advice, plus.

Answer:

The work of this thing is the rise of water level, the pressure increases in the pipe, to promote the diaphragm, driving the closure of contacts.I think you can check that the connecting pipe is leaking. The screw is too tight; besides, it is possible to measure whether the contact of the switch is good or not.
Did you turn on the machine when you blew it with your mouth? If I turn on or not, I don't know. But if you do not boot, you can not guarantee the normal operation of the sensor, there is a possibility that the sensor tube is too short, the pressure does not meet the requirements, the sensor does not move. You try a little longer, the longer part should be lowered, don't hang on it, it's better to lower the joint on the outer cylinder.
The pressure sensor is not bad, and it is also the bad contact, replaced after the first connected barrel interface, the best sizing or using circlip fastened to the root, drop some water, let the water pipe see and then connected with the pressure sensor on one end of the tube (and glue or is spring) and no leakage, (see water, pour some water, or blow)You unplug the inlet mouth pressure sensor has the sound of Da Da (that is, contact action of sound) when measured with a multimeter, confirm the ring closed contact is now
