Help Please: Problem with a La Pavoni Domus Bar Service

[Seafoamgreen]

Hi! My La Pavoni domus bar makes my house main fuse go, after being on a few minutes. I guess its something wrong with the heater element and wanted to take it apart to have a look. Have taken off the four screws in the four corners. Whats the next step to have it apart, the two pieces are very hard stuck together. See pic. Thanks!

Hi, should this work with Schaerer Siena? I need to increase steam temperature on 2 machines. Please let me know.
Thank you
