My cordless Bosch drill/driver will only work the first time the switch is pressed after attaching the battery. As soon as I release the pressure, it won’t work again until I remove the battery and replace it. Then, once again, it only works the first time the switch is pressed, and then... Nothing. Highly infuriating! It’s exactly the same with different batteries, so I don’t think it’s a battery problem. The problem is the same in forward and reverse, and in drill and screwdriver functions. Please can anyone help diagnose the fault? I’d be really grateful! Thank you.
