E16 error appears when trying to start any program; cooker may click but not heat.

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

Stuck-open heater relay on PCB, Burned triac controlling heating element, Cold solder joints on power components

Safety first: Unplug the cooker. PCB-level repairs involve mains voltage and should only be done by electronics technicians.

Listen for relay click: When starting a program, listen closely. No click may indicate a failed relay or control signal.
Inspect PCB (advanced): Remove the control board and look for burnt spots, cracked solder joints, or bulging components near the heater relay or triac.
Component replacement: Replace the faulty relay/triac or the entire PCB with a genuine Midea part. Do not bypass safety components.
