  1. Thanks

    If all three anti dust fans rotate, but have error then check fan rotation sensors. Look levels on F620, F621 and F622 connectors ( pin 3 ) . There should see changes, when fan stopped and when fan rotate. Hold fan ( do not allow to rotate ) and then release. You should see changes on pin 3. 
    If rotation sensors work, but still have error then check connectors. Rotation sensors are connected to PDC13 pin 1, 4 and 7 ( there signals from F622, F621 and F620 ) . 
    If all OK, but still have errors then faulty PDC20, CTL20, or some connector on them.

    E-2502 means fan does not rotate, rotating sensor malfunction, bad connections, missing power supply, or faulty pcb. To say more need minilab model.
