    • After disassembling the machine, it's easy to find the thermostats. They are attached to the top of the boiler with clips. There are two thermostats:

    • 95 ° C - brewing temperature (just below the boiling point of water)

    • 127 ° C - steaming temperature (just below the boiling point of water)

    • You can test the thermostats with a multimeter set to the resistance (ohms) setting. These thermostats are "normally-closed" which means at room temperature, the thermostat switch is closed. The meter should show close to 0 ohms when connected to the thermostat terminals.

    • You can remove the thermostats and check to see that they open when their temperature setting is reached. Carefully use a heatgun and an infrared thermometer to heat the thermostat above their set point. If you overheat them, you will melt the plastic case and destroy them. (Not that I did anything like that.... :-) )

    • The connectors on these generic thermostats need 2 modifications to work with the Saeco Poemia:

    • Cut/file the terminal width by about 1mm. I used a small file.

    • Bend the terminals at a right-angle to match the originals.

    • The mounting tabs are different than the original, but they work just fine under the spring clip.

    • Be sure to put some heat sink compound between the thermostat and the top of the boiler to insure accurate temperature sensing. Any low-cost type will be fine.

    • After I replaced the thermostats and tested the machine, I checked the temperature of the boiler with a multimeter and temperature probe. I put the temperature probe under the thermostat clip.

    • While testing, I noticed water and steam coming out of the boiler around one of the heating element terminals. Uh oh... I took apart the boiler and replaced the silicone o-ring gaskets. The video was very helpful to disassemble and reassemble the boiler. Checked again - no leaks!

Use generic thermostats to make this low-cost repair.
