Microwave shows E20 and sensor defrost or weight defrost functions do not operate correctly.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Incorrect user input, Faulty sensor algorithm in control PCB, Defective internal sensor (if equipped), Firmware error

Steps:

1. Verify settings: Ensure you are entering the correct food type and weight as specified in the Vida manual.
2. Power reset: Unplug for 5 minutes and plug back in to clear any temporary logic error.
3. Test manual defrost: Use manual power and time settings to defrost. If manual modes work but E20 appears only on auto defrost, the issue is likely in the control logic.

If E20 persists, the control PCB may require replacement or firmware update, which must be performed by an authorized service center.
