While removing the failed heating element in my Saeco (Estro 410) espresso machine for replacement, I noticed a white (creamy and caulk like) substance between the two thermostats and the boiler body. It is not corrosion and it was certainly applied during manufacture, as I am the orginal owner of this machine and have not taken it apart previously. I guess that it was applied to improve the heat conductivity between the thermostats and boiler body, so that they operate at the correct temperatures. However, I am not sure.
Most of this white substance came off or was spread around during disasembly of the machine and there is much less of it now between the thermostats and the boiler body. My questions are these:
1) What is this white stuff and what is it's purpose?
2) Do I need to apply more of this substance (or a substitute) to the thermostats for my machine to work properly?
3) If yes, where can I get this white substance (or substitute)?
Thanks for any info on this subject.
