Thanks for the suggestion. I had already cut the ends of the hose but it remains the same without making the slightest noise or signal that the engine wants to run normally. The hose is not broken either. Also the pressure switch and door block cables I measured continuity to the electronic card and they are not broken if you see other possible options I appreciate your response and thanks to you or another person

How do I prove it ? What I did was blow it double the hose and I see that the air remains there in the pressure switch, if you give me any suggestions to verify if the diaphragm is broken or I will not put it into practice I wait for your response and thank you

Regards Carlos._To know if the diaphragm is broken by blowing gently and steadily (when the washer is turned off) you should hear a sound like "click" without having to bend the sleeve afterwards._ If the washer was on and the washing stage was programmed , when blowing through the hose and the diaphragm being in good condition, the solenoid valves would stop working._ If they are kept running and no water level sensor error is shown, the two possibilities to be presented would be: (continued) .... ..

(continued) .. 1.-That the diaphragm is broken and 2.-That on the card one of the triacs that feed the solenoid valves is direct and would have to be replaced._ For the 2nd case it is very easy to determine it. the cable of the washing machine and without touching the panel you observe that at least one of the solenoid valves allows water to pass through or simply emits noise while the water stopcock is closed, it is clear indication that the triac that feeds that solenoid valve should be changed. 3rd option would be to disassemble the electronic pressure switch and check the diaphragm, but it is not necessary.

It is not necessary because the test of blowing through the sleeve towards the electronic pressure switch allows to determine if the sound is heard or not. Try to see. Thank you and Greetings.

Hello I tell you the following, today I decided to disassemble the entire electrical system of the washing machine and disconnect all the connectors of the card I measured continuity in all the cables and there is no broken cable I reconnected everything as it was, I started the washing machine again and the result was the same, does not give any signal to the engine or to wash or squeeze but if it continues doing the same if water enters the washing machine and does not stop filling. Then I give it pause and put it to squeeze and if it drops the water and after two minutes or so gives the signal E4

Carlos: __ What colors are the 3 wires that connect to the pressure switch? _ Which of these three wires is connected by a bridge with the door switch located in the solenoid valve compartment? _ What is the color of the wire that Does the door switch go to the power board? _There are at least 2 types of electronic pressure switches: _1.-One with electronic card and 2.-The other with two ceramic capacitors ._In the latter the middle terminal is negative pole and with both ends must yield 2 equal values in a range of 2.4 vdc to 5 vdc ._ (continued) ...

In addition, if the pressure switch is 3 wires and you only get one reading instead of two readings, the fault is in the card and the funny thing is that the error code of the water level sensor is not shown in the digital display. What I ask again: Do you have the manual of that washing machine model? Thanks and Regards.

Thank you for your interest I have several things to tell you, after assembling the electrical system as I decided to measure current in the three wires that go to the pressure switch and there is no current in the two corner wires but if there is current between the middle wire and one of the corners as I could see in a video the current enters through the two wires of the corners, I decide to take out the pressure switch and measure current in the connector and at that precise moment it began to wash that seemed strange because I had no water and the pressure switch was not connected, so I turn off the washing machine

CARLOS ALBERTO GRAJALES O

And I program it to wash and I hope and it does nothing I measure voltage to the pressure switch connector and start washing, now if it washes if it squeezes it does not say E4 but it only does so at the moment that I measure the current in the pressure switch connector my question is why ? What does my texter have that touching that connector works well? and when I remove the pressure switch, I should not send a signal so that the water inlet solenoid valves work well, so what is wrong with my washing machine?

I connect the pressure switch as it is original and full and full, it does not stop, I put it to squeeze if it drops the water but it does not turn the tub and mark E4 I remove the pressure switch the program to wash begins to enter water and when it goes in half I decide With my texter measure current in the pressure switch connector and start washing when making the change to squeeze I have to touch that connector with my texter to work well, so what do I do? Can you help me I wait for your answer

Ok thanks for the suggestion to have these data I inform you what if I can tell you it is already that the pressure switch had already disassembled it and if it has two train identical ceramics the first test I already did it I removed the pressure switch I put it to wash and start filling the tub of water I can not leave it 5 minutes as you say because you throw the full and full water and keep filling that is the only thing that I have done then I measure the voltage and inform you in advance thank you

Friend thanks for the suggestions and if you are right that washing machine has me marry as you said, tomorrow I inform you exactly the voltage of the pressure switch connector has three wires the one in the middle is brown one end terminal is light blue and the other end is dark blue , and indeed between the two blues it does not measure current but between the brown and the corner terminals if there is current tomorrow I tell you exactly how much it measures but I think it is 2.5 vdc

Little friend I did just like you did and this is what happened == I waited 5 minutes and the digital viewfinder there was no signal the voltage was 2 vdc without any change then I gave the wash signal with the closed water inlet tap and the voltage was the same, I inform you that my measuring texter is not of the latest generation but if it helps me example to measure 2.5 it does not reflect it on the screen but if the 2 bone measures exact it is 1 volt 2 volts 3 volts, he continued ,,, then I put it to squeeze the voltage is the same and automatically starts bouncing the water without turning the tub and it is there continuous

Greetings Carlos._ It is possible that the error of the water level sensor is not shown because if it reaches voltage but that voltage is too low for the pressure switch to work properly._ If you had read with the tester either 3 vdc or 4 vdc or 5 vdc the thing would be different in your favor._ In my way of seeing the fault is in the power card._ The voltage is very low and could be due to deteriorated resistances or capacitors electrolytes devalued ._ At this point a good electronic technician could check the card and corroborate the tensions and therefore replace the devalued parts ._ (continued

You can try to make a small test with the help of two 1.5 volt double A batteries. ._To do this, it is very important that the brown wire is the negative pole while the other two wires correspond to the positive pole._What to do? _The negative pole of the battery is connected to the brown wire and the positive pole of the battery will be connected to the light blue cable ._ (continued) .....

The other battery would be connected by its negative pole the brown wire while the dark blue wire would be connected by its positive pole._ This way you would be feeding the water level sensor with a direct current voltage of about Approximately 3.5 vdc at 4 vdc to both ceramic capacitors._Values that exceed the minimum 2.5 vdc in each case._ I cannot give you 100% guarantee that it works but it is only an idea in view of the low voltage supplied by the card Power to the electronic pressure switch.

Greetings Carlos._ I do not know any video in relation to what I have raised._ Theoretically the water level sensor requires a continuous voltage of up to 5 vdc and not less than 2.4 vdc to be fed from one side and can exchange Information with the micro-controller on the other side. In view of the tester's behavior without the sensor being connected, I deduce that the help with a pair of 1.5 volt AA batteries as proposed is feasible that the sensor respond when both ceramic capacitors receive the referred voltage ._ (continued) ...
