TLDR
On your BAKERLUX SHOP.Pro unit, error code WC01 indicates a temperature probe warning within the hood system, suggesting either a dislodged connection or a faulty probe. Verify the probe's connection to the P7 socket on the hood power board. If connections are secure, measure the probe's impedance to confirm its integrity.
Technical Details
Repair Steps:
- Safety First: Before proceeding, ensure the oven is completely powered off and disconnected from the main electrical supply to prevent electric shock.
- Locate the Hood Power Board: Access the hood section of your UNOX BAKERLUX SHOP.Pro oven and identify the main power board within.
- Inspect the Temperature Probe Connection: Carefully locate the P7 socket on the hood power board. Check that the temperature probe’s connector is securely seated and free from corrosion or damage. Re-seat the connector firmly if it appears loose.
- Measure Temperature Probe Impedance: Disconnect the temperature probe from the P7 socket. Using a multimeter set to ohms, measure the impedance across the probe’s terminals. At an ambient temperature of 25 °C (77 °F), the probe should ideally read approximately 110 ohms. Significant deviations (e.g., open circuit, very high or very low resistance) indicate a faulty probe.
- Replace the Temperature Probe: If the impedance reading is incorrect or the probe shows signs of physical damage, replace the temperature probe with a genuine UNOX spare part. Ensure proper routing and secure connection to the P7 socket.
- Replace the Hood Power Board: If the temperature probe tests good (correct impedance) and is securely connected, but the WC01 error persists, the issue likely lies with the hood power board itself. Replace the power board, ensuring all connections are properly transferred from the old board to the new one.
- Restore Power and Test: Once all components are securely reconnected, restore power to the oven and test its operation. Monitor for the WC01 error code. If the error persists, further diagnostics by a qualified technician may be required.
Common Questions:
Q: What does the WC01 error code signify on my UNOX BAKERLUX SHOP.Pro oven?
A: The WC01 error code on a UNOX BAKERLUX SHOP.Pro oven indicates a warning related to the hood’s temperature probe, suggesting it may be disconnected or faulty, impacting temperature monitoring.
Q: How can I verify if the temperature probe is working correctly?
A: To verify, first ensure the temperature probe is securely connected to the P7 socket on the hood power board. Then, use a multimeter set to ohms to measure its impedance; it should read approximately 110 ohms at 25 °C (77 °F).
Q: What steps should I take if replacing the temperature probe does not resolve the WC01 error?
A: If replacing the temperature probe does not clear the WC01 error, and its impedance tests correctly, the issue may lie with the hood power board itself. In this scenario, the next step would be to replace the hood power board.
