For the SHE3AR7xUC manual family, CL identifies Child Lock. The documented lock uses the left-arrow (<) control; On/Off remains available while the other buttons are locked.
Models covered
SHE3AR75UC within the SHE3AR7xUC family shown in manual 9000 633 139; match arrow controls and full suffix. Not a universal Bosch CL sequence.
Stop and isolate power before permitted user maintenance, and let water cool. Watch for sharp debris. Do not reach blindly into a sump, open electrical panels or use drain-opening chemicals. Stay clear of water near electrical equipment.
Compare the behavior
Match the documented control, cycle or feature before interpreting the result. The comparison below keeps normal model behavior separate from an unresolved fault.
| Observed state | Interpretation / next step |
|---|---|
| CL while pressing a key | Check the documented Child Lock state. |
| On/Off works but other keys do not | Consistent with the documented lock behavior. |
| Unlocked, controls still fail | Record the separate response problem. |
Model-specific checks
Check the panel family
Match the full SHE3AR75UC E-Nr and the Cycle Select arrow layout to manual 9000 633 139. Some retailer answers call the key “C,” while this manual identifies it with the < symbol. Use the diagram supplied for your revision instead of looking for an unrelated three-second setting on a newer Bosch.
Release the control lock
Press and hold the < button until the Child Lock indicator turns off or the CL indication clears as described in the manual. This is a control-state change, not a forced-door procedure. The manual notes that CL may only appear while a button is held; its absence at rest does not by itself establish that the controls are unlocked.
Compare the next response
After unlocking, check whether normal cycle selection responds at the appropriate operating stage. If it does, there is no evidence from the former CL state alone that the control board needs replacement. If buttons still do not respond, record which buttons work and whether the cycle is already active.
Keep supervision separate
The panel lock does not replace supervision or safe storage of detergents. Do not test it by letting a child operate the dishwasher. If the documented key cannot release the lock, have Bosch confirm the exact panel revision before trying combinations from another model or removing the fascia.
What to record next
This reconciles the symbol used in the actual manual with inconsistent button naming in search results, and explains why a briefly disappearing CL can mislead an owner.
When to stop and get help
Only carry out maintenance permitted in your model’s manual. For service, note the full model number and suffix, displayed code, selected cycle and what happened during the checks. Leave internal wiring, gas components, pumps and safety devices to a qualified professional. A symptom alone does not identify a failed part.
