The large power light blinks all the time. The machine seems to work fine.

switch or motor failure

Check for a filter where the air blows out of the machine. Could be clogged.

1. There is some confusion over models. I've seen "B40" models and instructions with only one size cup button, both labeled B40. I own one stamped "B40" on the bottom, and it has two buttons -- small and large. FWIW, small = 8 oz, large = 10 oz.

2. These reset instructions from another site seemed to do something
What to Do If Your Keurig Won Brew Cup Barista

So.. this is what I did that worked for mine: 1) Hold down Auto-Off and LARGE cup at same time. (all lights should hold steady ON) 2) press SMALL cup while still holding Auto-Off and LARGE cup 3) Release all three, press LARGE cup again.. all lights should go off. 4) Unplug for about 5 - 10 second, plug back in. SHOULD WORK!

3. On *_my_* B40, remove the K-cup, close the door, fill the reservoir. Unplug and replug the B40. All lights should be off.

Pressing "Auto Off" and "Large Cup" together will turn on 3 lights (Heating, Add Water, Power) for about 3 seconds. Doesn't matter how long the buttons are pressed or what order they are released.

I tried lots of add-on combinations: e.g. press button x, press x multiple times, press x while lights are still on, press x after lights are off, press buttons x and y together, press x then y, press x and/or y while still holding Auto and Large, release Auto but not Large and press x, etc.

Nothing gave any confirmation that a reset was accepted. All lights always turned off after 3 seconds. Maybe Reset is only 1 step, i.e. Auto+Large together?

I don't know if you already solved the problem, but did you check what the maximum output power of your aircraft is? The nespresso machine needs about 1250 Watts, which is a lot of power. A vacuum cleaner or microwave use less power than that (maybe between 800 - 1000 Watts). Maybe that difference is the reason. Also, you mentioned that you converted from 220V 50Hz to 120V 60Hz. I think you only converted the voltage, a frequency converter would cost thousands of dollars.

how can I reset my Le Cube? Volumes have changed.

Honeywell compact refrigerator model # 88031 making a clicking noise, not cooling, interior light blinks, and the fans in back are not working properly....seems as if it's not getting full power. worked fine for about a year and justed stopped.

Mine was doing that for the past week. I think it was indicating there had been a power outage but that the clock had not reset to zeros. I changed the time a couple of minutes and it stopped.

I had a similar problem where both Small and Large cup buttons on mine blinked intermittently. I did a reset of the large and small cup flow levels based on the following and it seems to work fine now:
1. Switch off power 2. Press and hold Large cup button 3. Switch on power while still holding down large cup button
See if that solves your problem.

The receiver has gone into a protect mode because something is wrong and it shuts down to prevent further damage. Could be a power supply or output amp issue.

I had the same problem. Really glad I came to this site. Had already tried to clean out the filter area. What really worked was unplugging and resetting the computer. Everything seem fine now.
