Bosch [LOC] fault codewhat it means and how to fix it

The child lock itself is simple: it stops the oven being operated, and holding the lock button until the symbol disappears releases it. The reason this needs a page is that Bosch cannot agree with themselves about what it looks like. Their UK website tells you to check whether the display shows a key symbol or LOC. We read six Bosch GB oven manuals and none of them mentions LOC anywhere — they describe the childproof lock as a key symbol, and elsewhere in the group as the word SAFE.

LOC is a display string other manufacturers use, and we could not verify it on any Bosch oven. So if your Bosch shows LOC, we cannot confirm from Bosch documentation that it is the child lock, and if you are hunting for LOC on your display because their website told you to, you may be looking for something your appliance never shows. The hold time is inconsistent too, though harmlessly so. Bosch’s manuals say approximately four seconds and their website says around five. Holding longer costs nothing, so use the larger figure.

1. 1

   Look for a key symbol on the display rather than the letters LOC. The key symbol is what Bosch’s own manuals describe, and it is the one we can confirm.

2. 2

   Press and hold the key or lock button until the symbol disappears. Bosch’s website says around five seconds and their manuals say roughly four, so hold for the longer of the two.

3. 3

   Try changing a setting to confirm the oven is responding again, which is Bosch’s own final step.

4. 4

   If your model has no dedicated lock button, check the manual. Bosch acknowledge that some models need a button combination and do not publish which.
