My Salter model 3003 kitchen scale shows Err when I turn it on. How can I fix this?
This means that it cannot calibrate itself because the sensor is out of range. This can happen if you drop it or overload it. Check the feet on each of the for corners and make sure they are not stuck, you can do this with the unit on and see if it registers any force on the pads when you press and release them or use a screw driver to lift them SLIGHTLY. There are a lot of youtube videos on how to check and repair them.
