Led weirdness

So I bought a second hand Digitakt a month or three ago and recently noticed the ‘red’ led on the lfo button not working. Sent an email off to Elektron and they were very helpful and referred me to the Australian distributor.
It’s been out for a few weeks I guess, I put in test mode and no red showing. But shows 0 errors.Now I turned it on today and the red is back. No idea what it could be. Maybe just lucky today and it’ll break again.

What did the distributor say?

They said send it to them but now the led works again . I’ll contact them again, just thought someone may have experienced the same thing before.
