E914 error but bike still working fine

[owenxcw150]

I have an Orbea Rise LT M10 630w and on the app it's showing e201 and e914 error codes. The bike is still working fine. Has anyone else had this?

@owenxcw150 - you've actually hit exactly the same combo I covered in your waterproofing thread, just this time the codes are showing up together in the app rather than stopping the bike dead.

The good news is that the two codes are linked. E914 and the very often related E201 (showing as E201002 in full) are created with the same timestamp and are almost never a drive unit fault - they point to a connection problem between the battery and the motor.

The fact the bike is still working fine is actually typical of this; it's logged a fault event rather than a fatal one.

E914 is always a clear indication of a contact problem between battery and drive unit, most often a bent, dirty, or corroded contact at the battery connector. And critically: never use a pressure washer or even a strong garden hose on a Shimano STePS-based bike, as that's one of the quickest ways to bring this on.

First thing to try: turn off the system, remove the battery and wait 5 minutes. If you then reinstall it, the code typically clears and you can keep riding.

While the battery's out, inspect the connector pins carefully. A bit of dielectric grease on the terminals helps stop dirt ingress and corrosion and can prevent the E914 from coming back.

If you want to dig deeper into the exact error subcode, the E-Tube Project app (Cyclist version via Bluetooth) lets you read the full error protocol - you'll get a 5 or 6 digit code rather than just the 3-digit version, which gives you much more specific fault information.

Worth doing before you go to a dealer, as it might tell you exactly what triggered it.

The E201002 variant is a known sporadic fault that still appears on the latest motor firmware 4.2.2 on some bikes, but in that case there's nothing to worry about - it's essentially a ghost in the system rather than a real problem. Check those connectors, get the full error code from E-Tube, and if it's recurring frequently rather than just once, your dealer should take a look under warranty.
