Why Is The Light On My Nespresso Machine Flashing?

The morning dash – we’ve all been there. Already 5 minutes late, but at the risk of being even later, there still seems to be time to snatch a cup of coffee before hurtling out the door.

With Nespresso that should be easy. Capsule – close – extract – done. But sometimes the world spits the dummy. The last thing we want to deal with (especially in an uncaffinated state) is waking up to see that our Nespresso machine has lights blinking madly and refusing to work.

Trying to decipher what the root cause is can be challenging, and let’s be fair, who has actually read the user manual?

Luckily, there are a few common Nespresso machine problems that could be the cause behind these blinking lights. Here are the 6 most likely reasons the lights on your Nespresso machine keeps flashing

  1. Stuck in descaling mode
  2. The lever isn’t’ fully down
  3. Low water level
  4. Capsule is stuck
  5. Buttons are wearing out
  6. Turn it off and on again

Now let’s discuss each of these in more detail.

1.  Machine in Descaling Mode

The most common reason why your Nespresso machine might be stuck with its lights flashing is when the machine is put into descaling mode.  If you find the machine has both lights flashing rapidly (i.e. faster than they would when the machine is warming up) then you may have accidentally entered a cleaning mode known as ‘descaling’

To fix this, hold down both the flashing buttons for at least 7 seconds or until you hear a beep.

The machine may start flashing again at a slower rate, this just means it has to warm up again. Once the lights stop flashing you should be good to go.

2.  The lever isn’t fully down

The capsule levers on most Nespresso machines have a habit of closing easily 90% of the way and then needing a bit of force to get it to snap completely closed. This can catch people out because there is a small microswitch inside the capsule mechanism that won’t be activated until the level is completely engaged.

Try checking that the lever is fully down, or open and close the machine again complete to make sure. Sometimes a coffee pod can get lodged sideways and prevent the mechanism from clicking into place.

3. Low Water Level

This one may seem obvious but when it’s 7:59 AM with a toddler screaming at you then I can assure you it’s not. Check the water tank to make sure that it’s not empty. If it has run out, simply top up the tank with fresh drinking water. Once inserted back into the machine the flashing lights should stop immediately.

4.  Blocked Capsules in Machine

From time to time your Nespresso machine may experience a blocked capsule. This may be from the pod  being stuck sideways, twisted, or sometimes means the capsule has failed to be pierced on both ends by the barbs on the capsule holder mechanism. This will result in your Nespresso machine trying its hardest to push water through a capsule that is completely blocked and won’t let any water through.

If you think this is the cause, then take the capsule out and check its orientation and that it’s being pierced at both ends correctly. If it hasn’t, try reloading the capture in the correct manner. Once you run the machine again the lights should stop blinking.

5.  Buttons are wearing out

Mechanical parts are prone to wear and tear and this is only exacerbated by the fact that’s the kitchen countertop is one of the dirtiest places in the house. Grease, gunk and grime can get into the tactile buttons of your espresso machine and get in the way of the electrical signal.

The easy fix if this happens is to press the button extra hard to see if you can make a connection, otherwise try the other lungo (big cup) button which may be in a better state of operation.

Of course, this is only a work around. If the problem persists, you’ll need to take the buttons apart to clean properly – or take the machine into your Nespresso dealer for a professional service.

6. Turn it off and on again

Ok, look, we know this isn’t What you’re hoping to hear but sometimes the best option is to simply turn the machine off and on again at the wall.

Like all electrical systems there’s an element of black magic involved and to appease the Nespresso gods a simple flick of the switch – wait 5 seconds – and flick on again could be all that’s needed.
