Another Cimbali M27 clogged with scale.

There are alot of these out here.  Such good work horses.  They go and go until there is a major clog, most people don’t even notice that it has been struggling for years.  Finally showed a solid sign when the pressure stat clogged and the points stayed on and the boiler overheated and the relief valve triggered.  There was a very thick and hard layer of scale in the bottom of the boiler and 1/3 of the element was toast.  Ceramic form the element was also freely accumulating in the boiler from the element.  Taps were leaking and there was a large area of rust on the top frame where the moisture accumulates from the hot water tap.  This was going to take at least 5 hours spanned out on 5 days.   Descaled with product over 8 times,  redid the clips on the element and the probe, changed many gaskets.

Quoted 5 hours, billed 5 hours.  New element, lots of gaskets.  Machine is almost rebuilt.
