Hey everyone, how to waterproof a 2025 Orbea Rise to prevent e914 error My bike's a Orbea Rise LT M10 630w.

The E914 error on Shimano EP8/EP801 systems is a connection fault, and on the Rise it's almost always moisture. The good news is you can do a fair amount to prevent it rather than waiting for it to bite you.

The Rise's harness plug connections are not sealed or waterproof from the factory, which is a bit of an oversight on Orbea's part given that people tend to ride these things in, you know, weather. Moisture gets into the connector pins, corrosion forms, and eventually the bike decides it's done for the day.

The practical prevention steps: • After any wet ride, unplug and inspect the main connector points, particularly the speed sensor wire where it meets the motor and the main battery/motor plug connections. These are the usual suspects.

• Clean male connector pins with a soft-bristle toothbrush and the female side with fuzzy pipe cleaners soaked in electrical contact cleaner. This takes about five minutes and is well worth doing regularly.

• One important caveat: Shimano does not recommend dielectric grease on the connections. It's non-conductive, which means it works against you rather than for you. Conductive grease with carbon or metal particles can help but over-application causes shorts between pins. Leave the grease alone and stick to contact cleaner.

• If you've already seen E914 pop up, unplug every connector point you can access, clean them with contact cleaner, and reconnect. That's resolved it for plenty of Rise owners who've had the same error after a soaking.

Worth knowing: if moisture has already gotten into the motor itself via the crank spindle seals, that's a more serious situation and a dealer visit is in order. But for routine prevention, the connector cleaning routine is where to start.
