Did you get the photo?
Expert:  KevinWhiteJA replied 7 months ago.

Thanks for that.

M in your microwave indicates it is in DEMO mode.

You will have to press and hold the START and STOP button together for around 15 seconds to deactivate demo.

Nothing happens when I do that ! Do I press anything first eg 800 button?
Expert:  KevinWhiteJA replied 7 months ago.

Leave it unplugged for 45 minutes and then try it again.

Customer: replied 7 months ago.
I tried again but nothing
Expert:  KevinWhiteJA replied 7 months ago.

OK, do this unplug it and press every button (one at a time).

Then plug it back after around 15 minutes and check again.

If the error code is still there, let me know

Customer: replied 7 months ago.
No good M is still displaying
Customer: replied 7 months ago.
The switches on the micro are digital so when you tell me press buttons ( start/stop) together they don’t respond
Expert:  KevinWhiteJA replied 7 months ago.

OK, press start and then stop, repeat this till 15 seconds.

If still it wont help, I am afraid the control board will need replacement.

Customer: replied 7 months ago.
No nothing! Who do I contact to replace board?
Expert:  KevinWhiteJA replied 7 months ago.

OK lets try one last time:

unplug the microwave and this time while its unplugged immediately press and hold the start and stop buttons together for 10 seconds.

Then plug it back within 5 minutes.

If this won't help Operating Module is available for £84 + repair charges.

You may contact Neff at 0344(###) ###-####to book repair.

If you have any further questions, don't hesitate to ask!
