What to do if NSK ENDO-MATE DT2 Dental equipment motor handpiece does not rotate, and '---' and the rotation speed are displayed alternately?

If the motor handpiece does not rotate, and '---' and the rotation speed are displayed alternately, the contra angle head may be clogged. Clean or replace the contra angle head. Alternatively, check the connection, as there might be a short circuit inside the motor handpiece or the motor handpiece cord.
