Red light is on (looks like an M) and I don't know why??
It means time to descale , however if you want to get rid of it, just press and hold the water button until it goes off.
To descale..fill the container with descaler and let water goes through the system by openning the valve and catch the descaler with a container. Turn off the machine a few minutes and start the process all over again for 1/2 hr, and finally with water to wash the system.(donot want to heat up the descaler too much)
