Possible Causes

Defective main control board, Loose power harness connections, Voltage fluctuations from supply, Internal board short

How to Fix / Troubleshooting

Safety first: Turn off the circuit breaker and verify power is off before touching internal wiring.

Steps:

  • Check outlet and breaker: Confirm the outlet has proper voltage and the breaker is not tripping. Avoid using extension cords.
  • Inspect power cord: Look for cuts, burns, or loose connections where the cord enters the Café combo.
  • Reseat control connectors: Access the main control board compartment and carefully reseat the power input and output harnesses.

When to call a technician: If code 15 remains, the main control board likely needs replacement. This should be done by a qualified technician due to live-voltage risks.
