Display shows a generic “Err” or “ERROR” message and beeps; no specific numeric code is given.

Safety first: Unplug the cooker before any disassembly.

• 1. Hard reset: Unplug the unit for at least 15 minutes to discharge internal capacitors. Plug back in and try a simple program with water only.
• 2. Check keypad: Press each button individually and ensure none are physically stuck or jammed. Clean the control panel surface with a slightly damp cloth; do not allow liquid to seep into the panel.
• 3. Inspect for moisture: If the control panel was exposed to steam or splashes, allow the unit to dry for 24 hours. Moisture can cause phantom button presses and error states.
• 4. Open and inspect board (advanced): Remove the control panel cover and inspect the main PCB for burned components, cracked solder joints, or corrosion around connectors.
• 5. Replace control board: If the error persists after reset and there is visible damage or no obvious external cause, replace the main control board / PCB with a PowerXL-compatible part.
• 6. Avoid surge damage: Use a surge protector to prevent future firmware or board damage from power spikes.
