I changed the broken coupler and now it doesn’t stop filling up! While it was filling up, I blew directly into the pressure switch and it stopped the water and the wash cycle started! So I assume that it is something else. Clearly, it not geting enough pressure from the tub to stop the water. What can it be? Thank you.
PS: I checked the tube coming to the pressure switch and it looks good. No cracks or anything… How would I double check it though?
Hi Bobby
To test to see if your water valves are stuck in the open position, disconnecting the power is the thing to do. If the water continues to come in then the valves are stuck and need to be replaced. However, this does not seem to be your problem since when you "blow" into your pressure switch you cause the control to tell the valves to close and they do.
Now the way these systems work is that the plastic tube running from the switch connects to the washer tub. As the tub fills will water, water enters the tube and increases the air pressure in the tube. When the air pressure gets high enough, it triggers the switch, which tells the control unit the tub is filled and to shut off the water valves. When you blew into the pressure switch, you mimicked this process.
Now what you need to do is to take off the cabinet and start the machine up. You should see water enter the tube. If it does not, then you did not clear the tube. If it does and the water does not shut off then either
- You have a hole in the tube and need to replace it.
or
- Your pressure switch assembly needs to be replaced because it is not responding to the increased pressure (your blowing into it may create higher pressure than the tube creates)
My expectation is that you will find the problem with the tube.
Argh! It is not the hose… Got the new hose and tried it but still the same thing! It doesn’t stop…
Can it be other than the pressure switch? Is there a way to check that out before shelling out $100+?
How can I check if there is enough pressure coming from the tub? At this point, I am thinking, it’s either the pressure switch or for some reason, there is not enough pressure created… Is there a part that creates that pressure?
Or just buy a new pressure switch and see if that’s gonna fix the problem and if not, I can always return it, right?
Don’t feel stupid, that is a very good question and actually you were doing the right thing.
Your transducer is your water level pressure switch and you were testing it correctly. (a tranducer is a pressure switch which uses variable current rather than a mechanical switch which the tranditional water pressure switch uses).
So we are back to the recommendation of replacing the pressure switch (the transducer) which unfortunately is a lot more expensive then the old water switch.
Talk with APP about returning it if it does not fix the problem, but I think it is highly likely this will solve it for you.
