Left hand side cover is probably off and excess light is getting onto the motor speed sensor. put the side cover back on and try it, most likely that will fix it. could also be the set screw on the right side is loose, error 1 means you have a speed problem. check gears and chain. only other part that has caused this in the past is the keypanel.
