What does calc mean lit up red on coffee machine my way

1 flash every 3 seconds means the pilot is lit and the gas valve is working normally. A solid red status light means the water heater is shutting down. Turn the gas control valve OFF and wait 10 minutes before attempting to relight the pilot

Yes I can under stand this you have done descaleing but you have not done descaleing in the proper way very thing has its sequence let take dolce gusto by pressing for few seconds the power button it will blink in green this means that the machine is now indescaleing mode when you're done you simply press the power of in this case you have told the machine that you want to do descaleing and after this the internal computer is reset to normal this is why you machine is still blinking because it had not been reset

push it for 5 second and if its still flashing doesn't matter turn the steam knob anti-clockwise end let the machine do to the descaling cyrcle, when then water tank emptied the rest of buttons starts to flashing, turn the knob off and your machine is ready!!

Perform a full descale. Take out the water reservoir and remove the Anti-calc filter. Put in 500ml (1 pint) water with 3-4 tablespoons of white vinegar (or apple cider vinegar). Put the water canister back in, the turn on the machine and press the manual button. Allow half of the liquid to go through, then stop. Leave the machine for about ten minutes, and then run the rest through. Empty the water reservoir and rinse, put back the Anti-Calc filter, put in another 500ml and press the manual button to flush it all through.

Calc is indicating that it's time to descale the lime build up inside your coffee maker. Most machines are easily cleaned by running a solution of 4 parts water to 1 part vinegar. Run this solution through a regular coffee cycle (no coffee). After running this solution, you may want to run straight water once more to ensure there's no vinegar aftertaste. Your machine will now be clean and the CALC message should disappear. If not, post back with the Model # of your Krups coffee maker for further instructions. Some machines have a Descale or Self Cleaning option built into them.

You've done it all correct but before you add the solution (making sure to remove the filter), try holding the descale button down for over three seconds. As long as the FILTER NO is your filter setting, this should work. You may want to try to descale more often in the future but hopefully this helps you get started NOW. Best of luck!

it means de"CALC"ify its detecting calcium build up the manual says to run white vinegar without the filter followed by two clean water cycles goto krups.com to download the manual

I have a Krups model FME4 and it means that you should descale the machine. Here's a link to the use and care instructions for my model, I assume it would be the same for yours.

My problem is that CALC continues to display even after I've descaled several times. Good luck with yours.
