i have now the problem that on Max performance the dyson turned off and the accu is blinking green, after ~20sec the green blinking turned off and it works again for again ~20sec then again turned off and green blinking. i have cleaned the dyson very carefully. i have blowed out all the filters. i have already the second accu but the accu is now also again ~2years old.
what can this be ?
