Stuck Rehau gauge

Several of my 17 main floor Rehau gauges are stuck and not reacting to a change in flow rate all showing zero. Any suggestions on methods to unstick them?

    You have to isolate the manifold and take them out and clean them. Sometimes they'll free up as you're unscrewing them from the manifold.

    The bottom of the gauge where it contacts the inside of the manifold creates a sort of screen. I have had issues with those screens clogging. They are pretty easy to take apart and clean.
