What Does The Flashing Steam Light Mean?

As mentioned above, the flashing steam light on your DeLonghi machine is an alert system designed to tell you when something isn’t quite right.

How To Fix The Delonghi Flashing Steam Light Issue?

Navigating through these issues can feel overwhelming. However, with the right guidance, fixing your DeLonghi machine can be much simpler than it seems. Let’s explore each of the solutions in depth:

Checking And Refilling The Water Level

One of the simplest reasons your machine’s steam light might be flashing is because the water tank is insufficiently filled. The machine needs enough water to create steam, and a low water level can interrupt this process. Here’s how to address this:

  1. Turn off your DeLonghi machine and unplug it from the power source.
  2. Remove the water tank from the machine. Make sure to do this gently to avoid any damage.
  3. Check the water level. If it’s low, fill it up with clean, preferably filtered, water up to the maximum line.
  4. Reattach the water tank to your machine, plug it in, and turn it on.
  5. Watch the steam light to see if it continues to flash. If it stops, you’ve successfully solved the problem!

Descaling The Machine

Over time, minerals from the water used in your machine can accumulate inside and cause a need for descaling. Descaling is a cleaning process that removes these mineral deposits, improving your machine’s performance and lifespan. Here’s how to do it:

  1. Purchase a DeLonghi-approved descaling solution. It’s best to use the brand-approved solution to avoid any possible damage to your machine.
  2. Remove the water tank, empty it, and then fill it with the descaler and water as per the descaler package instructions.
  3. Place a large container under the coffee outlet and the steam nozzle to catch the descaling solution.
  4. Follow your DeLonghi machine’s descaling procedure as outlined in the user manual.
  5. After descaling, rinse the water tank thoroughly and fill it with fresh water.
  6. Run the machine with just water a couple of times to flush out any remaining descaling solution.

Ensuring The Machine Is At Optimal Temperature

If your machine is too cold or too hot, it may not work properly, causing the steam light to flash. Here’s how to handle this:

  1. If the machine is too cold, move it to a warmer location and wait for it to reach room temperature before using it.
  2. If the machine is too hot, turn it off and unplug it. Allow it to cool down naturally. Avoid placing it in a cold area abruptly as sudden temperature changes can damage it.

Clearing Blockages From The Steam Wand

A blockage in the steam wand can interrupt the steam flow, causing the light to flash. Here’s how to clear any blockages:

  1. Unplug the machine and allow it to cool.
  2. Remove the steam wand if your model allows it.
  3. Use a thin, sharp object, like a needle, to gently poke inside the steam wand and clear any potential blockages.
  4. Rinse the steam wand under warm water to help dislodge any remaining particles.
  5. Reattach the steam wand, plug in the machine, and test to see if the light is still flashing.

By following these methods, you’ll have a good chance of solving the DeLonghi flashing steam light issue. But remember, if the problem persists, reach out to DeLonghi’s customer support or a professional technician for further help. Your morning cup of coffee awaits!
