I got ERR 049E DRV SENS today. I rode it almost 20 miles today, turned off, because I was riding with a friend with an analog bike. I got home, washed it with the screen taped off and got that error about an hour after I dried it off. And, I didn’t use any high pressure water stream. Got any ideas what’s wrong?

Yeah, I found that, thanks. I took the battery out. It was only slightly moist. I let everything dry, put it back in and still have the error. Does anyone know what that error mean?S?
I purchased my EXe in Oct 2022. I had electrical system problems after some (very gentle) washes of the bike (including having the display unit and charging port taped over) ... so since then I only wash the tyres / wheels with a gentle hosing, but the rest of the bike I just wipe with a slightly damp cloth. Never had an issue since. <touch wood>

It means something is wrong with the signal from the torque sensor, just take it to a dealer and let them run diagnostics or whatever, you might need a new motor.
Don't tell them it happened after you washed your bike, just say you got caught out in the rain and then the next time you tried to use your bike it had that error :p
I dont know how waterproof those motors are maybe some water got inside on the crank somehow.

The torque sensor is probably directly wrapped around the crank inside the motor just on the other side of the bearings.

According to the specs from tq the motor is rated to ip67 which is pretty good, and should mean you don't get any moisture related issues. But a few people are seeing issues so maybe it doesn't really meet ip67 standards? Or maybe there is a QC issue with some motors, or maybe these errors are not moisture related at all

Thanks guys for the help. It won’t reset. So, it’ll go back to the shop. Good thing is, my girlfriend runs the shop. Her guy that works with the EXe diagnostics will be back on Tuesday. It’s supposed to rain here anyways.

I'm interested to know what the result is. Can you inform us, please?

I got it to reset. And, it’s been fine. I took it to the shop a couple weeks ago for an update. Our guy saw that it had a couple of error codes, he contacted Trek and yesterday it got a new motor. I rode it home and I swear the new motor has more power in the high mode. High mode is the only mode I used on the way home. And when I got home I realized that the motor setting had reverted back to the default settings. Before the motor swap, I had High mode at full power, all three sliders over to the right. This weekend I’ll take it for a long ride and see how it goes.

I have a Scott Lumen eRide 910 and got error REM BTN ERR 5403 when trying to go into the setup mode as described in the (TREK?) manual chapter 5;
For the V01 display on a Scott Lumen the procedure to go into setup mode is different.
You need to switch on the motor (not off as with the Trek display) and then press and hold the display button and the remote down button for more than 5 seconds to enter setup.

The error code shown tells you that you pressed a remote button while trying to start the motor.

See the correct manual for your display here https://www.tq-ebike.com/fileadmin/.../HPR50_DisplayV01_Remote_BHEN_Rev0107_Web.pdf
