Error codeE-01 / E01
ApplianceMicrowave
Samsung lists E01, shown with a dash as E-01, under an open error for its microwaves.
E-01: key details
Shows as: E-01, sometimes E01
Samsung calls it: open error
Series: Samsung files it among the current-generation microwaves.
Steps to try when E-01 shows
Stop power reaching the oven: unplug it, or turn off the breaker feeding it. If the microwave got wet, for instance from a spill or steam from a cooktop, let it dry. Where moisture is not the issue, the wait is 60 seconds before power returns. A repeat of E01 on the display is the cue to ask for service.
Other codes in the same list
C-F2: Samsung lists a communication error. E-02 is the entry for a cooking time setting over error (microwave).
