My accucheck compact GT is poorly I used it yesterday morning, and the motor sounded sick then, but read my blood ok, then when i turned it off(so it kicks out the used strip), it wouldnt and kept coming up with error E17. So i removed the drum, refitted it and now it tries to find the empty slot, but fails. I inserted a new drum this morning and again, it sounds rough, cant push the strip right thru and beeps saying E13 error :roll: I presume I need a new one?
