I've got the GHL 2.1 doser, and one of the pumps is making a fast clicking sound while dosing. The other two pumps are quiet. Any idea what this noise could be? Is it a sign of something bad? Can I fix it easily?

I too am having a similar issue on brand new 2.1 unit with 3 pump heads unfortunately means erratic calibration to say the least and affects all 3 heads in my case.
