Precor Error 05, Key Depressed at Power Up Probable Cause 1. A key is permanently depressed on the display.
2. An interface chip (IC) has failed in the upper PCA's keypad.
3. Liquid (cleaning solution or sweat) may be on the surface of a touch sensitive display.
Corrective Action

1. Disconnect the keypad cable from the upper PCA. Reset power to the machine. If the Error 05 is eliminated, the keypad is the cause and should be replaced.
2. Disconnect the keypad cable from the upper PCA. Reset power to the machine. If the Error 05 still appears, the upper PCA* is the cause and should be replaced. *Upper PCA's most commonly do not come with software. Remove the software (chip) from the existing upper PCA prior to replacement and install into the new upper PCA.
3. Wipe away all liquid from the touch sensitive display. Reset power to the unit. If the Error 05 is eliminated, the liquid was the cause.

Precor Error Code 05

Typically on the Precor Treadmills if there are errors on the unit, you can press and hold the stop button for 3-5 seconds and it will go into the error log. Not sure what model you have.
E-2 is not what normally shows up on the screen. Do you mean Error 2 was displayed? From what I have read on Error 2's it could be a upper PCA issue, or possibly a dip in AC input during the power up sequence.
Treadmills require a dedicated line, meaning it is on its own dedicated circuit on your fuse panel/circuit breaker.
What exactly is the treadmill doing? Is it constantly showing Error 2 on the screen? Call up Precor tech support. They will be able to give you advice, and or get you connected with an authorized Precor factory trained technician who will be able to get you back up and running.
