This asko cooktop child lock guide covers a situation that comes up often enough to be worth a dedicated look: touch controls that suddenly stop responding to normal taps can mean the child lock or control lock is engaged, or it can mean something else entirely is wrong with the panel. Telling the two apart before calling for service saves a lot of unnecessary frustration, since the fix for a locked panel takes seconds.
What the lock is actually for
Child lock and control lock serve slightly different but related purposes on a touch-control induction or gas hob. Child lock is specifically meant to prevent small children from accidentally activating a burner or changing a setting mid-cook, disabling the touch controls except for the specific unlock sequence. Control lock more broadly prevents any accidental input, including from an adult brushing against the panel while wiping down the surface, which matters more on a glass-ceramic touch panel than it would on physical knobs that require deliberate pressure to turn.
How the lock typically engages and releases
The exact sequence to engage or release a lock varies by model and generation, but it commonly involves pressing and holding a specific icon or combination of controls for several seconds until a lock indicator appears or disappears on the display. Because this sequence requires a deliberate hold rather than a quick tap, it is not something that engages accidentally from a single stray touch, though a spill or a heavy object resting on the panel for an extended period can occasionally trigger it unintentionally.
When a dirty panel looks like a stuck lock
This is where things genuinely overlap with a documented problem: the Er03 code on the HI1621G family specifically means the control panel is dirty or has water on it, and a panel in that state can behave very similarly to a locked one, refusing to register normal taps until it is cleaned. Before assuming your lock is stuck, wipe the entire control panel dry with a clean cloth and try the unlock sequence again, since a wet or grimy panel is a far more common cause of unresponsive controls than a genuine lock malfunction.
If the unlock sequence genuinely does not work
If the panel is confirmed clean and dry and the correct unlock sequence for your specific model still does not release the lock, that points toward a control-panel failure rather than user error, and is worth having checked directly rather than repeating the sequence indefinitely. Confirm you are using the correct sequence for your exact model, since it does vary across Asko’s hob generations, before concluding the panel itself has failed.
Using the lock day to day
Households with young children generally benefit from engaging child lock any time the hob is not actively in use, and reserving control lock for cleaning the surface, so the two features genuinely serve their intended purposes rather than becoming an occasional annoyance.
