I think the old Coffee Gaggia Classic (w/o solenoid) that I'm trying to renovate does not produce sufficiently hot water. Measured in a variety of ways with different thermometers, the results all point to a water temperature of 140-160 F.
This temperature range is achieved after the machine has been left to heat up for more than one hour. Whether the thermometer is in a glass, receiving water directly from the brew head or through the pf seems not to matter. The styrofoam cup method produces similar results, as does the temperature taken at the steam outlet with the setting at steam (which I thought would be hotter).
I have so far searched in vain in an attempt to discover if the problem might be anywhere other than in the thermostat and, if not, if the thermostat is adjustable, and if not, is it replaceable?
Any help much appreciated.
