Overflow - no waste flow

I found today that the water sample tube was off on the doser side. Some water in the bottom of the cabinet. There is a lot of salt build up on the outside of the kh director.
I completed an empty measurement cell through the software, but the doser head does not turn and sounds like it is in trouble.

So I took the blue plastic cover off and refitted it. Head now turning ok and the measurement cell has been emptied. I assume this is the problem with the plastic dosing heads. The pressure must have built up and it popped the tube off the sample water because the kh director wasnt draining.

I dont have time to sort it tonight so I left it in error with the last measurement of 0dkh. Will need to sort it tomorrow.

Will there be any damage from water inside the unit? I didnt see a dot on the inside of the blue head cover. Does that mean I need to replace those?

I had the sample water head stop last week but got it going again. That just lead to bad measurement.

How do people ensure that the tubes stay attached to the dosing headsup? I am a little cautious now.
