Rational SCC - Error Service 25: CleanJet Water Circulation Faulty

⚠️ Caution / Monitor Closely

TLDR

On your SelfCookingCenter unit, Service 25 indicates a CleanJet water circulation issue, meaning water isn't reaching the fan wheel properly during the cleaning cycle. This can be caused by a faulty pump, blockages in the water pipe, or the absence of racks/trolley in the cabinet. Inspect the pump, clear any obstructions, and ensure the cooking chamber is correctly loaded before cleaning.

Technical Details

Repair Steps:

  1. Verify Racks/Trolley Presence: Ensure the cooking chamber has either the standard racks or a VarioMobil trolley correctly inserted and closed. The CleanJet system requires the chamber to be properly configured for water circulation to hit the fan wheel effectively.
  2. Inspect Water Supply and Pressure: Confirm that the unit has adequate water supply pressure. A low water pressure can prevent the CleanJet pump from effectively circulating water. Check external shut-off valves and the unit’s internal water connection.
  3. Check CleanJet Nozzles and Spray Arm: Open the cooking chamber door and visually inspect the CleanJet spray nozzles and the rotating spray arm. Look for any calcium buildup, food debris, or foreign objects that might be obstructing the water flow or preventing the fan wheel from being hit. Clean as necessary.
  4. Examine Water Pipes for Obstructions: Power off and unplug the unit. Access the rear or side panels (depending on model) to inspect the water pipes leading to and from the CleanJet pump for any visible kinks, blockages, or leaks. Foreign bodies, such as dissolved food particles or scale, can impede circulation.
  5. Test the CleanJet Pump (SC-Pump): With the unit safely powered off and isolated, use a multimeter to check the continuity and resistance of the CleanJet pump (often referred to as the SC-Pump on SCC models). If the pump motor is seized or damaged, it will not circulate water. Professional replacement may be necessary if the pump is faulty.
  6. Reset the Unit: After performing the above checks and corrections, power cycle the RATIONAL SelfCookingCenter. Turn off the main power switch, wait for 30 seconds, then power it back on. Attempt to initiate a CleanJet cycle to see if the error has cleared.

Common Questions:

Q: What is the RATIONAL CleanJet system?

A: The RATIONAL CleanJet system is an automatic cleaning function in SelfCookingCenter units designed to efficiently clean the cooking chamber without manual scrubbing. It uses a rotating spray arm and specific cleaning agents to ensure hygienic operation.

Q: Can I continue cooking if Service 25 appears?

A: Yes, you can typically continue cooking with a Service 25 error, as this issue primarily affects the automatic cleaning cycle. However, the unit will not be able to perform self-cleaning until the circulation fault is resolved, which can lead to hygiene issues if not addressed promptly.

Q: How can I prevent CleanJet water circulation problems?

A: To prevent CleanJet issues, regularly delime your unit, ensure proper water filtration, always load racks or a trolley during cleaning cycles, and perform routine visual inspections of the spray nozzles and water pipes for any obstructions or buildup.

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.
