Error 2 in 5417R,how do i solve it?thanks - Eppendorf Centrifuge 5417r Refrigerated Microcentrifuge d

Error 2 on this model indicates that the imbalance sensor is tripped. If you run the unit with an empty rotor and it does not error, then it simply means that your load was imbalanced. Make sure to put vials into the unit opposite each other, as below.

If it displays "Error 2" with an empty rotor and you did not notice a vibration, then the imbalance sensor is broken and must be replaced. Do not attempt to run the centrifuge without the imbalance sensor, as serious injury may result.

I repair these machines, but you would have to ship it to me in Ohio, which would probably be very expensive.

Here is a rotor balance chart:
