What to do if NSK Surgic Pro2 shows error E1?
- SSteven BeckerAug 14, 2025
Error E1 on your NSK dental equipment can be caused by extended use under heavy load, a short circuit in the motor, or a motor cord failure. First, ensure the motor cord is securely re-connected, as insufficient electrical contact may be the issue. If the error persists after re-connecting the cord, request a repair.
