Turn the ice maker off so the problem does not get worse. If it comes back, it needs a visit. ### Does Sub-Zero EC30 mean my food is at risk? No, EC30 is about the ice maker and says nothing about cooling. The ice maker has stopped because its water valve solenoid was triggered too many times. Keep an eye on temperatures anyway, and treat any second code as its own issue. ### Can I reset EC30 and keep making ice? Sub-Zero gives no owner reset for this one. The advice is to switch the ice maker off so the problem does not grow, then arrange service. Giving the technician the code plus both compartment temperatures speeds things up. --- **[Read on the site: Sub-Zero refrigerator showing EC30](https://refrigeratorrepair.center/error-codes/sub-zero-ec30/)** **[Book a visit with RefrigeratorRepair.center](https://refrigeratorrepair.center/schedule/)**
