Smoker displays E15 and will not start; sometimes appears after long storage.

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

Corrupted non-volatile memory on control board, Failed RTC circuit, Low internal backup capacitor, Firmware glitch

Safety first: Unplug the smoker before any panel removal.

Factory reset (if available): Consult the user manual for a factory reset or settings clear procedure and perform it.
Power cycle: Unplug the unit for 10–15 minutes, then reconnect and check if E15 clears.
Stable power: Plug the smoker directly into a wall outlet (no long extension cords) to ensure stable voltage.
Board replacement: If E15 persists and no reset procedure resolves it, the main control PCB’s memory or RTC circuit is likely defective and the board should be replaced.
