Technical Details

Repair Steps:

  1. Safety First: Immediately disconnect the RATIONAL iCombi Classic unit from its main power supply. This is crucial to prevent electrical shock or further damage to components due to water ingress.
  2. Perform a Thorough Visual Inspection: Carefully inspect the unit’s exterior, paying close attention to the base, drip tray, and beneath the cooking chamber. Look for any visible signs of water, moisture, leaks, or water stains. Use a flashlight to check less accessible areas.
  3. Check Drain System Integrity: Inspect the main drain hose connected to the iCombi Classic. Ensure it is not kinked, blocked, or disconnected. Verify that the floor drain is clear and capable of handling the unit’s wastewater flow without backing up. Examine the drain trap for any blockages.
  4. Inspect Water Inlet Connections: Verify that all external water inlet connections and hoses (both fresh water and SoftSteam/Hygiene steam) are securely tightened and free from any leaks. Check the integrity of the water supply lines leading to the oven.
  5. Internal Plumbing and Component Inspection: If comfortable and competent, carefully open the side panels of the unit (after ensuring power is off and appropriate safety measures are taken). Inspect all internal hoses, water valves, and pipe connections for any signs of leaks or loose fittings. Pay particular attention to connections around the steam generator, fresh water solenoid valves, and spray arms.
  6. Examine the Water Detection Sensor: The iCombi Classic utilizes a water detection sensor (often a float switch or conductivity sensor) in the base pan to trigger this error. Locate this sensor and inspect it for proper seating, electrical connection, and cleanliness. It might be obstructed, stuck in a ‘water detected’ position, or faulty. Clean any debris around it.
  7. Condensate Management System: Ensure the condensate drain system within the oven is functioning correctly. Blockages in the condensate drain can cause water to accumulate and overflow into the base, triggering this error.
  8. Re-test and Monitor: After identifying and rectifying the source of the water, meticulously dry all affected areas. Reassemble the unit, restore power, and carefully monitor its operation for any recurrence of the error or new leaks. If the error persists, contact a qualified RATIONAL service technician.

Common Questions:

Q: Why does my iCombi Classic display error code 63 “Water detected”?

A: This error commonly indicates a water leak within the oven’s internal components, a blockage in the drain system causing water to back up, or a malfunction of the water detection sensor located in the unit’s base.

Q: Is it safe to continue using my iCombi Classic if error code 63 is active?

A: No, it is strongly advised to cease operation immediately and disconnect power. Water in critical areas can cause severe damage to electronic components, lead to equipment failure, or create an electrical safety hazard.

Q: What are the most common leak points to check when troubleshooting error 63 on an iCombi Classic?

A: Frequent leak points include loose or damaged water inlet hoses, compromised drain lines or connections, internal plumbing around the steam generator, solenoid valves, and spray arm assemblies. The base tray should also be checked for overflows.
