I purchased an 80 mm water cooled spindle and a CW-3000 chiller. I have the water lines connected between the spindle and chiller. I have filled the chiller with distilled water. My CNC and the chiller are located in the basement of my home, so the ambient temperature is about 75°F. This is the first time I’m trying to run the chiller. When I turn it on, after a few seconds the alarm sounds and the error light comes on and the code in the temperature display shows E0 22. Can anyone tell me what might cause this? Thanks.
All i can think of is coolant flowing?

I’m having the same situation you described with the CW-3000 chiller. Where you able to get it working and if so, could you explain how
Google’s AI is rather helpful with this E0 error. Not sure where the 22 is coming into play, that could be bouncing between error code and temp… cause 22 sounds close to ambient temp if it were in C.
If flow is the problem, you’ll need to open the cover which is basically two C shaped large metal panels clam-shelled together. As in all the tiny silver screws around the perimeter of the metal panel with the two black handles on it… those all need to come out. I think there’s at least 16 iirr.
This will let you see the internals of the chiller. It’s not scarry promise.
Open the cover and see if there are any kinked hoses. It is safe to plug in the chiller after opening the cover so long as you don’t put your hands in there without knowing what you’re touching.
The high power electrical is mostly covered in the back.
Fix any kinked hoses… and see if that helps.
Also pay attention to any electrical smells you might catch.
Took cover off and didn’t see and kink and or any loose electrical connections. The pump seam to be seems to be running, but does stops at flow meter. Took the flow meter cover off and there are no obstructions. Then took hose off flow meter and pump would not pump out any fluid out of thehose unless I lowered it below the pump. The picture shows it stopping at flow meter
