ECM Giotto
Another home unit suffers from excessive scale...
Notes on this model:
Well known equipment maker ECM of Italy has been selling the Giotto for home users for several years. The components are average quality for the class. Lacks a group pressure gauge.
Reason For service:
Customer has had recurring issues with leaks on boiler fittings. Pressure stat may be bad. Requests to have hot water dispenser removed and to have a group pressure gauge installed.
Diagnostic & Repair:
Found the level probe was not responding, causing boiler to overfill (scale damage). Vac valve leaks (scale damage). Removed hot water assy. and found fittings, tubes fairly choked with scale. Will Descale entire system. Group pressure gauge will require some creativity to mount without awkward appearance. P-stat is operating as it should - i will confirm that customer wants it swapped.
Installed a Group pressure gauge in the hot water opening. works perfect, looks pretty good. I had to cut a piece of pipe to mount the gauge on the surface of the unit...
