got your fix, its a calcium buildup in the heat exchanger, and more than likely the rest of the unit, you will need to flush the unit with about 4 gallons of vinegar, you will need to recirculate it for about 20 mins through the unit, then flush with clean water, hook it back up, it might take a couple of mins for it to run properly, but it will, I have had the same problem with Rinnai on demand hot water systems, and it worked like a charm, check the filter thats inline as well, make sure it isnt plugged, clean if needed, also if you dont have a soft water system inplace, you might want to think about buying one and having it installed, that will reduce this from happening again for alot longer period of time, hope that helps

SOURCE: Siemens central heating control
I have a Siemens "Radio" Room Stat - the receiver has switched itself off. How do I restart it. I have pressed the restart button and the reset - nothing happens except for red light flashing and then off. I do not have the instructions. Where might I get them?
