Precor Error 30, 31, 32 and 33, Communications Error Probable Cause 1. Bad interconnect cable between upper PCA and lower PCA.
2. Interconnect cable is mistakenly plugged into the CSAFE connector at the upper PCA.
3. Elliptical 5.17 equipped with old software version 1.01 in upper and lower PCA.
4. Upper and lower PCAs have mismatched software.
5. Another component plugged onto the PCA is overloading the +5VDC power supply.
6. Bad lower PCA.
7. Bad upper PCA.
Corrective Action
  1. Test unit with a know good interconnect cable or test the interconnect cable for continuity. Replace interconnect cable if necessary.
  2. Disconnect the interconnect cable from the CSAFE connector and attach to the proper position on the upper PCA.3.
  3. Replace the upper and lower software of the 5.17 elliptical with the most current versions.4.
  4. If one of the PCAs is found to have software version 1.01, replace it with the most current software version.
  5. Disconnect all components from the upper and lower PCA leaving the data cable connecting between the upper and lower PCAs and the AC power going to the lower PCA. If the unit shows any error other than the error 3x, reconnect components one at a time. Reset power between each newly connected component until the error 3x reappears. Whichever component was last connected when the error 3x reappears, is the cause for the error. Replace the faulty component.
  6. Test unit with a known good lower PCA. Replace the lower PCA if necessary.
  7. Test unit with a known good upper PCA. Replace the upper PCA if necessary.

bar soap on the ramps where the wheels travel until the shine wears off the wheels. I see it at warranty calls every week

Precor Efx-5.33... | Answered on Apr 03, 2014


I imagine if 106 people have responded then at least one may have asked if the squeak is coming from the wheels. I see it every week under warranty. the ramps and wheels need time to wear a little and until then they can be hideous. its counter intuitive being as that the ramps and wheels are supposed to be cleaned all the time. BUT, when new they make a racket and the easiest way to shut them up is a to rub a bar of soap on the ramp where the wheels travel. it shuts them up and holds a little dust over time to wear the shine off the wheels and make them act as they should. Beyond that I would need to know where the sound was coming from if not there.

If only one of the upper or lower software is version 1.01, replace the version 1.01 softwarewith the most current version of software.5. Substitute a known good lower PCA to determine if the lower PCA is defective.6. Substitute a known good upper PCA determine if the upper PCAs defective.

Are you sure the PSU is functioning? Check it with a multimeter set for DC Voltage. Compare what it is putting out to what the factory specs are.
