Answer to continue safely
Is it safe to keep using?
Yes. E7 is a protective lock, not an appliance fault. Once unlocked the cooktop is fully safe to use. The lock feature itself is a safety benefit.
Can I reset the code?
Yes. Hold the lock button for 3 seconds to clear E7. A power-cycle also clears the lock. If a physical button fault is causing E7, a technician is required.
When to stop immediately?
Stop if you notice: Stop investigating and call a technician if E7 cannot be cleared using the lock button and power-cycle after clearing the panel surface., Do not attempt to use the cooktop if it relocks immediately after unlocking without any object on the panel..
Symptoms You May Notice
All zone controls refuse to activate
Touching zone power buttons or adjusting power levels has no effect — the cooktop appears powered but completely ignores all user inputs.
E7 or lock icon displayed on panel
The display shows E7 or a padlock symbol, indicating the child lock or auto-lock feature is engaged and preventing zone activation.
Cooktop locks up when items rest on panel
Placing a pot lid, cloth, or kitchen tool on the front of the cooktop (where the controls are located) triggers the auto-lock within a few seconds.
Panel locked after a liquid spill
A boil-over that spreads liquid over the touch controls triggers simultaneous multi-zone detection, causing the panel to self-lock as a safety measure.
Possible Causes
Child lock intentionally activated
A household member — often a child — has held the lock button long enough to activate the child lock feature, which is indistinguishable from a fault to other users.
DIY PossibleObject on touch zone controls
Touch-capacitive controls respond to anything with a dielectric signature, including pots, cloths, and food items, causing auto-lock.
DIY PossibleFailed lock button or touch IC
If the lock button itself has failed in a depressed state, the cooktop may permanently display E7 and cannot be unlocked by the normal method.
Requires ProfessionalSafe Checks You Can Do
-
1
Unlock using the lock button
Locate the lock or key icon on the control panel. Press and hold it for 3 seconds. The E7 code or padlock symbol should disappear and normal zone operation should resume.
On some Asko models the unlock sequence is: press and hold the Power button until the panel beeps, then hold the Lock button.
-
2
Clear the panel surface
Remove all items from the cooktop surface, including pot lids resting near the front controls. Wipe the panel area dry with a clean cloth. Wait 30 seconds and then attempt to unlock.
If the panel re-locks as soon as an item is placed near the front, check whether your cooktop's control zone overlaps with the normal front-zone pan placement area — some layouts require careful pan positioning.

3
Power-cycle if lock button is unresponsive
If holding the lock button for 3–5 seconds produces no response, switch the cooktop off at the breaker for 5 minutes. Restore power and immediately try the unlock sequence before placing any pan on the surface.
Refer to your model's quick-start guide for the specific lock/unlock sequence — it varies slightly between Asko HI series generations.
When to Call a Professional
Contact a qualified technician if:
- E7 persists after a power-cycle and panel clear with no objects on the cooktop.
- The lock button produces no response — either no beep or no change in display — suggesting button failure.
- E7 appears simultaneously with other error codes, suggesting a broader control board fault rather than a simple lock condition.
