Profitec Pro 400: Testing the Heating ElementUpdated 5 months ago

Tools Needed:
- 3mm Allen wrench or hex driver.
- Multimeter
- Towel

1. Start by draining the machine. Then unplug the machine and allow it to cool.

2. Tilt the machine up onto its front, carefully resting it on the group head. You may want to place a towel under the machine or group head to prevent marring the finish.
(There is no need to remove the side panels at this time.)


3. Locate the access panel on the underside of the machine and remove it by unscrewing the four 3mm Allen head screws as indicated.


4. Identify the heating element. (You may need to move the water line out of the way.)


5. Unplug the electrical connections from the heating element.



6. Set the multimeter to the resistance setting in the 20Ω range, then probe the heating element legs.


7. A working heating element will display continuity with a resistance reading of ~10Ω-20Ω. A heating element that shows no continuity or that displays a resistance significantly greater than 20Ω is likely faulty.
