TLDR
On your iCombi Pro unit, error code 110 indicates a fault with the SC pump during a Carechemie cleaning cycle in the steam generator. This issue typically stems from a blocked pump, clogged supply lines, or a defective pump motor. Prompt inspection of the cleaning agent system is crucial to restore automated hygiene functions.
Technical Details
Repair Steps:
- Verify Carechemie Supply: Ensure that the Carechemie (cleaning agent) supply, whether tabs or liquid, is correctly loaded and not depleted. Check for any obstructions in the dispenser for tablets or issues with the suction line for liquid systems.
- Inspect the SC Pump: Locate the SC pump (typically in the technical compartment) and visually inspect it. Look for any signs of physical damage, loose connections, or unusual noises if the unit attempts to operate the pump. Check if the pump impeller is jammed or clogged with debris.
- Check Water/Carechemie Lines: Examine all associated lines leading to and from the SC pump and steam generator for blockages, kinks, or leaks. Mineral deposits or cleaning agent residue can build up, restricting flow. Disconnect and manually clean lines if blockages are suspected.
- Test Pump Functionality (Service Access): If you have access to the service menu, attempt to manually activate the SC pump to observe its operation. Listen for the pump motor engaging and verify if water or cleaning solution is being circulated. If the pump runs but no flow is detected, it may indicate an internal blockage or impeller issue.
- Examine Dosing System Components: Inspect the sensors and valves associated with the Carechemie dosing system. A faulty dosing valve or level sensor can prevent the correct delivery of cleaning agent, triggering the pump fault. Ensure electrical connections are secure and corrosion-free.
- Contact Certified Service: If the above steps do not resolve the issue, or if a component like the SC pump motor, control board, or critical sensors are determined to be faulty, professional assistance is required. Do not attempt complex repairs without proper training and tools, as it may void warranties or cause further damage.
Common Questions:
Q: What is the SC pump’s role in the iCombi Pro?
A: The SC pump (Self-Cleaning pump) is a critical component responsible for circulating the Carechemie cleaning and care agents throughout the cooking cabinet and steam generator during the automated cleaning cycles, ensuring optimal hygiene and performance.
Q: Can I continue cooking if error 110 is active?
A: While the oven may still operate for cooking, it is strongly advised to resolve error 110 promptly. Failure to do so will prevent effective automated cleaning, potentially leading to scale build-up, hygiene issues, and reduced equipment lifespan.
Q: How can I prevent future SC pump faults?
A: Regular use of RATIONAL Carechemie products, ensuring proper loading of cleaning agents, and performing routine preventive maintenance checks on water quality and system components can help prevent SC pump faults. Avoid using non-approved cleaning agents.
