Troubleshooting 

Problems you can handle yourself 

If problems other than those described in the following tables arise, you must consult your nearest au-
thorized service. 

 

 

Error 

Behavior of the centrifuge 

Possible cause(s) and measures to be taken 

Displays remain dark 

The motor stops. 
The rotor stops without 
braking. 
The lid cannot be opened. 

Mains failure or not connected

 

1.  Check the mains connection. 
2.  If the mains connection is OK, call the nearest Service. 

Displays fail briefly 

The motor stops suddenly. 
The rotor stops without 
braking. 
The display reads "br", see br. 

Brief interruption of mains supply 

1.  Check whether the plug is plugged in properly. 
2.  Restart the centrifuge. 

Lid cannot be opened 

 

Pressing the "lid" key has no 
effect. 

Lid not correctly engaged or lid warped. 

Press lid down in the middle of the front section. 

Heat monitoring relays in the lid unlocking magnets have 
been actuated  

(repeated pressing of the "lid" key within a few seconds). 
Press key again after a short pause (approx. 1 min).
