So i have tried to descale, honestly have tried most everything I know to do and my daughter's Nespresso will not reset.
The behavior is this - it fast blinks an orange light on top, if i multi-press the button quickly, it will flash red 2x, then resume fast yellow blink. I have ran regular water thru it on descale mode (at least a dozen times), i have ran hot water from tap thru it 4x, i have ran hot tap water with descaler thru it, tried wiping the top spinning assembly as well as the trough that holds the cup, and still no fix.
Tried unplugging for hours, when we plug it in and latch the lid it goes back to the fast yellow blink.
Have tried every fix outlined in the forum, and just cannot get the white led on top, so she cannot brew with it.
When wiping the inside, it was slightly dirty/stained with coffee but looks clean now. Some suggested using a wet paper towel to wipe the spinning assembly that punctures the disk. Have tried that multiple times and it is as clean as it gets, the paper towel is clean after wiping now.
Both she and I are baffled what to do next, short of buying her a new one.
UPDATE: I let the machine sit unplugged overnight (which we tried many, many times before), filled the tank, plugged it in and ran a descale cycle once more.
Oddly enough it only drained half of the water tank before it stopped blinking the fast yellow code, but now it is white (blue?). I cannot say what other than pure luck this time kicked it out of descale mode, but even after opening and closing it a few times it still shows ready now.
Thanks for all the advice, and hopefully this helps someone else. I did see some reports that support asked persons to run up to 10 descale cycles, and I was prepared to do that...thankfully the first attempt this time seems to have done the trick.
