Answer to continue safely
Is it safe to keep using?
Yes. L is a user-safety feature, not a fault. The cooktop is fully functional and safe — it simply needs to be unlocked using the procedure above before normal operation can resume.
Can I reset the code?
Yes. The child lock is deactivated by pressing and holding the lock key for 3–5 seconds. A full power-cycle at the circuit breaker also clears it on most models. No service is required unless the touch key itself is faulty.
When to stop immediately?
Stop if you notice: Lock cannot be deactivated by the key hold procedure or power-cycle, Touch panel is unresponsive even after confirming the surface is clean and dry.
Symptoms You May Notice
L displayed and all controls unresponsive
Every touch control is locked; pressing zone or power buttons has no effect and L remains on the display.
Cooktop appears dead after cleaning
After wiping the surface, all controls are locked — the cleaning mode or an accidental long-press activated the child lock.
Only the lock symbol visible on panel
All zone indicators are off and only a padlock or L symbol is visible, with no response to any input.
Possible Causes
Child lock intentionally set
The lock function was activated deliberately by pressing and holding the designated lock key for 3–5 seconds.
DIY PossibleAccidental activation during cleaning
A cloth or sponge resting on the touch panel held the lock key long enough to activate the function.
DIY PossibleCapacitive touch control malfunction
A faulty touch key is registering a permanent press, keeping the lock active and preventing deactivation through normal means.
Requires ProfessionalSafe Checks You Can Do
-
1
Locate and press the lock key
Find the padlock icon or key symbol on the touch panel. Press and hold it for 3–5 seconds until L disappears and a beep confirms deactivation.
The lock key position varies by model — check the top right or front centre of the control panel. Refer to your model's Quick Reference Guide if the key is not obvious.
-
2
Ensure the surface is dry
Wipe the control panel area dry before attempting to unlock. Moisture on the capacitive touch surface can interfere with key registration and prevent the unlock gesture from being recognised.
Water droplets on the touch panel can simulate a finger press and keep the lock active.

3
Power-cycle if lock will not deactivate
If the normal unlock procedure fails, switch off the cooktop at the circuit breaker for 30 seconds and restore power. The child lock does not persist through a full power cycle on most Fisher & Paykel models.
After a power-cycle, the cooktop returns to its default unlocked state on CI series induction models.
When to Call a Professional
Contact a qualified technician if:
- Capacitive touch key stuck in permanent-press state requires PCB replacement
- Touch panel overlay replacement is a technician repair if the key has physically failed
