Tools Needed:
Phillips screwdriver
17mm wrench (or crow's foot and ratchet if needed)
Scouring pad or wire brush
Teflon tape (if needed)
Begin with your machine unplugged and fully cooled/depressurized.
2. Locate the brew boiler temperature probe and disconnect the wiring harness.
3. Use the 17mm wrench to loosen and remove the temperature probe from the brew boiler. A crow's foot and ratchet may be needed if you are having difficulties getting enough leverage to break the fitting free.
4. Clean the temperature probe with a scouring pad or wire brush. The metal should be shiny as pictured below.
5. Reinstall and reconnect the temperature probe. If the temperature probe's rubber gasket was damaged or lost during removal wrap the probe's threads with Teflon tape to ensure that there are no leaks.
