How i fixed error 500 on Bosch Ebike motor 

Looks like is water inside the motor and i have had some bad bearings and the water whose getting inside U should take it to service

Looks like this error in mine bike comes back when I wash the bike so after one day the error disappeared I only use a bottle and a cloth but still getting this error So probably is there abad connection or a wire is broken I have to investigate more

Salut, am spalat si eu bicicleta si am sceeasi eroare, ce pot face ?

you cant fix error 500
