E6 appears on the display and the cooker will not start any program.

Safety first: Disconnect the appliance from mains power before any inspection.

• Power reset: Unplug the cooker for at least 10 minutes to allow internal capacitors to discharge, then plug back in and try again.
• Check for moisture: Inspect the control panel area for signs of liquid ingress (condensation, spills). If moisture is present, leave the unit unplugged in a dry, warm area for 24 hours.
• Inspect the power cord and plug: Ensure there is no damage or overheating at the plug or cord entry.
• Internal inspection (advanced): Remove the outer housing screws to access the main PCB. Look for burnt components, bulging capacitors, or damaged tracks.
• Keypad/touch panel check: Disconnect the keypad or touch panel ribbon cable from the PCB and power on briefly. If E6 changes or clears, the panel may be shorted and require replacement.
• Replace PCB if needed: If obvious PCB damage is found or E6 persists despite checks, replace the main control board with a Hisense-compatible module. This should be done by a qualified technician.
