there is no adjustment needed for this. the room is adjusted at the factory, and should remain that way.
there is no air in the lines. thats fluid pressure you hear bleeding off.
what is happening is there is a small piece of debris in the line that has lodged in the orifice of the valve. by opening the valve, the material is moved, and the valve can close completely.
if it does it again, open both valves and run the pump 15 to 20 seconds. close them and run the room. next time, replace the retract valve. that is the recommended hwh fix.
my suggestion is to find and download service manual and read it. it has a ton of information and diagnostic procedures to do a correct diagnosis of the system.
i know i beat the service manual bit to death, but if you dont already know how to fix it, what other source do you have?
there is no magic reset button or fuse to replace on hwh systems. it does involve testing before replacing.
i also know it takes a couple of weeks to get a reply back from hwh. it pays to invest a little of your time in order to give the hwh tech information that you should have already gotten in order for him to help you. this is why it takes so long for them to get to you. we dont hang up on anyone, even if you dont know what a pump is, let alone where its at.
if you need help, i can do that. my cell is 1-602-549-3638, my email is
