Time for a little thread necromancy. I just wanted to add on here, after I encountered this heater error problem on an Ultimaker 2, and determined the cause was the AC/DC adapter power supply. Our heater error was caused by using the wrong power supply with the Ultimaker 2. Our was not broken, we just used the wrong supply. It turns out that the OtherMill machine (from OtherLab) uses a power supply with exactly the same 4-pin connector, and a similar looking power supply, but it runs at 15v and a lower maximum current. The UM2 seemed to be operating fine, with no visible damage or heater pull-out, but could not reach operating temperature. The symptom of limited ability to heat led me to believe that a current limit was the cause. Since the Ultimaker and OtherMill are sure to be common fixtures in many makerspaces and workshops, this accidental power supply swap may happen again. This was the first hit on Google when searching for the heater error.
