Error codeE-X1 / EX1
ApplianceMicrowave
Quick answer
E-X1 is Samsung's microwave code for additional open error. Reset the power; request service if it returns.
Model compatibility: Samsung reuses codes across series and model years, so E-X1 / EX1 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
E-X1 means additional open error.
Samsung’s microwave list gives E-X1 the label Additional open error, and the unit shows it when that fault is detected. Current-generation Samsung microwaves are the ones that use this code.
What to do first
Begin at the plug or the breaker and turn the microwave off at one of them. Let any moisture dry off, or simply pause for 60 seconds if there is none. Then plug it in or turn the breaker on and test it. A code that comes back after the reset is the point to ask for service. Keep the cabinet closed and leave deeper checks to a technician.
Codes that look similar
Other microwave codes worth a look: E-81 (communication open error), E-71 (steam sensor open error) and E-X2 (additional short error).
