Some models you can disable the lights, can you advise the model number please.
Unfortunately this is not something you can switch off, the only thing I can suggest is remove the panel and unplug the cable which goes to the LED strip.
Removing the panel is rather fiddley (as its not designed for being done as part of maintenance by the consumer). It should be just clipped in place, and can be removed by using a flat screw driver or spatula to prise it off.
If your not comfortable with this I can recommend an engineer to come out and do this for you, if you provide me your postcode.
Correct, the screw just holds the cosmetic fascia in place.
Please let me know how you got on accessing the LED.
Just wanted to check in to see how you got on with the LED?
Thanks for updating me, I am just conscious the question has been open for some time and they tend to close automatically after a few day of inactivity.
I will wait to hear back, if you get stuck send a picture over, but am sure it should be rather self explanatory once you remove the fascia.
