Shimano e8000 overheating

[The voz]

Hi anyone having a problem with e8000 mines fine for 1-2 hours then get e10 error code took it to shimano service centre said put new software on it although E-TUBE was saying had latest they removed all error codes but same thing has happened again but this time motor cut out in boost briefly 3x at 10mph with no error code I’ve cleaned all electric connections it’s doing me nut in

Check alignment of the speed sensor magnet with the sensor itself - I has this issue and it turned out the magnet wasn't close enough to the sensor - it was line up correctly but needed a washed behind the sensor itself to close the distance - when under loas the flex in the wheel was enough to cause it to momentarily cut the power, not helped by the fact my wheel had gone out of true.

So with washer behind speed sensor all ports clean lastest firmware running last week all day at bike park no issues 2 batteries great today 2 hrs in all hell up with error code e10 and w13 I’m sure it’s an overheating issue .as your after riding for an hour ?no battery it worked again it’s now back at service centre anyone else had this

Maybe ride in trail mode instead of boost too long. I rode in trail mode, climbing over 1 hour, no issue. I use boost occasionally, 1 time using boost less than 10 min on long boring road climb, no issue.

I had these error codes sometime last year, ended up with motor being replaced. Codes started out only happening occasionaly and powering off sytem and back on I would be able to finish my ride. Until 1 ride I got these codes and it never went away. If reinstalling software / updates did not fix the problem, I also did this as it was recommended, you most likely will end up with a new motor.

Hopefully that’s what will happen took video of problem as it’s fine for a bit I’m getting a bit fed up with shimano it’s ruining bike park days that you take time off work for thinking if pulling trigger on kenevo instead
