Welp, the hits just keep coming. Here's the latest debacle.

Yesterday I lost water pressure at the wand. Went out and checked the waterbox and noticed it was really low. Fresh water was coming in, but kind of sputtering. I went to the front of the machine, disconnected the water supply and bled it. There's audible air hissing, but I can't seem to bleed all of the air out.

Initially I thought that I might possibly have blockage in one of the inline water filters (there's 3), or maybe the hose clamps need tightening so I cleaned them all (they looked fine) and tightened the screws on the clamps... still nothing.

I do have a water softener between my fresh tank and the demand pump, so I bled the hoses there as well... no change. I ran a garden hose both into the front of the machine and into the water softener, and everything worked fine? I'm completely stumped. It's like the demand pump is full of air and it won't bleed completely.

Obviously there must be an air leak, but I can't figure out where. I replaced the hose that connects from the fresh water tank in to the water softener,thinking that maybe I sprung a pinhole leak, but there's no change. Has anyone else ever had such a problem? The demand pump is the big boy with the bladder tank, and it isn't even a year old.

Suck the water though the pump with the vacuum system, turn on and off the pump real quick. Regulate the vacuum pressure with hand so as not to damage pump.
That should get the air out to see if it works.
I have no experience with TM Pumps, so my advice may be wrong.

Why was the water box so low? Could be something super simple like debris plugging up the tip of your water hose not letting enough water into your water box. Or a bad hose bid not opening up very well.
That's what I'm trying to figure out. From everything I've pulled apart so far, I can't find a blockage. What's weird is when I run a garden hose directly to the water softener, it works fine... although I realize that it pushes pressure to the demand pump. It has to be pulling air from somewhere though, and I'm seriously stumped. Of course it snowed like crazy overnight :/ I've been encapping all day so haven't dug in with fresh eyes today.

You have 3 inline filters between the demand pump and the machine?? I hope not.
dump the output of the demand pump into a bucket and make sure you are getting the correct flow out. Probably like 4-5 gpm. Look at the pump, it will tell you.

Sorry for the late response, been playing catch up. All that I can figure is that I must have seriously pulled some air. I did run dry on accident doing some tile awhile back, and the must have done it... all I can figure. I ran water through the system for close to an hour and it finally seems to have bled all of it out.

As far as inline filters between the pump itself and the machine, no... there are none. I have 3 between the softener and the demand pump, sorry for the confusion.
