Neff int Oven [U1524N0GB – fd:8804] -SP- Cild/Permanent lock activating by itself…

[neon_3SP_glow]

Customers oven was displaying ‘-SP-‘ indicating that the ‘Permanent lock’ was initiated, and oven functions were prevented.

I cancelled the lock by following the instructions listed in manual (repeatedly, and rapidly moving the oven selection switch between the Zero position and one click Left) and all seemed well, oven functions were working correctly…

However, whilst I was writting an invoice, the machine reverted back to showing ‘_SP-‘, despite no one moving the selection switch. It activated by itself.

Any experience with this fault, please? I suspect the control pcb (which appears to be obsolete).

Many thanks.

did you click it 3 times or 6 ?

Hmm, reading that suggests that the lock should indeed ‘switch itself on’ after 30 seconds ‘if’ the permanent lock is activated prior to using the oven.

So, it looks like:

* If permanent lock is accidentally activated, it will show up by automatically activating 30 seconds after using the oven (once the selection switch is in the zero position).

* Three clicks will allow the user to operate the oven. But, to cancel the feature altogether, after those three clicks, a further 6 clicks are required.

Thanks for bringing that to my attention electrofix, much appreciated. I did read through the manual, but it appears i misinterpreted the instructions.

Ps. What a hideous system!

SOLVED:

Just finishing this thread…

The process listed above resolved the issue. I was able to explain it to the customer over the phone.

Presumably, they had previously accidentally activated the permanent lock.
