TLDR
On your iCombi Pro unit, error code 13 indicates a problem with the level electrode in the steam generator. This sensor monitors the water level, crucial for safe and efficient steam production. Addressing this issue promptly, typically by replacing the faulty electrode, will restore your combi oven's full steaming capabilities.
Technical Details
Repair Steps:
- Safety First: Disconnect the RATIONAL iCombi Pro from the main power supply and allow it to cool completely before performing any service. Ensure all pressure is released from the steam generator.
- Access the Steam Generator: Depending on the iCombi Pro model, you may need to remove rear or side panels to gain access to the steam generator housing. Refer to your unit’s service manual for exact panel removal instructions.
- Locate and Inspect the Level Electrode: The level electrode is typically found on the top or side of the steam generator, often secured by a fitting. Carefully disconnect the wiring harness. Visually inspect the electrode for heavy scale buildup, corrosion, physical damage, or loose connections.
- Clean or Replace the Electrode: If light scale is present and the electrode appears otherwise sound, attempt to carefully clean it with a descaling solution or a soft brush. However, given the error, replacement of the level electrode (part number may vary, consult Rational parts diagram) is often the most reliable solution. Ensure the replacement part is genuine RATIONAL.
- Reinstall and Reconnect: Install the new or cleaned level electrode, ensuring a tight seal and proper electrical connections. Reattach all panels securely.
- Test and Reset: Restore power to the iCombi Pro. Initiate a steam cooking program or a cleaning cycle to test the new electrode’s function. The error code should clear automatically; if not, perform a service reset through the SmartPanel interface (consult the service manual for specific steps).
Common Questions:
Q: What is the function of the level electrode in my iCombi Pro?
A: The level electrode continuously monitors the water level within the steam generator. This ensures the generator always has adequate water for steam production and prevents dry-boiling, which can cause significant damage to the heating elements.
Q: Can I continue to use my iCombi Pro with a level electrode error?
A: It is not recommended. Operating with a faulty level electrode can lead to inconsistent steam production, damage to heating elements from lack of water, or potential overfilling and leaks. Repairing it promptly ensures optimal performance and prevents further issues.
Q: How often should the level electrode be inspected or replaced?
A: Inspection frequency depends on water quality and usage. In areas with hard water, scale buildup can necessitate more frequent checks. Rational generally recommends professional inspection during routine preventative maintenance, with replacement as needed based on condition or error codes.
When to call a technician
Consider calling a certified technician if:
- The error keeps coming back after you've tried the steps above.
- You're not comfortable doing the checks or repairs yourself.
- You notice unusual noise, smell, or behaviour.
- Equipment is under warranty and you want official service.
- You need the unit back in service quickly with minimal downtime.
