Hello, my coffee machine (De’Longhi ECAM 23.460.S) is behaving strangely and I’d like your opinion on what to check or do.
When the machine is running, it sometimes randomly starts dispensing hot water, and then it rapidly flashes as if it is both making and not making hot water—like it doesn’t really know what it wants to do, as if there’s a wrong signal somewhere. The same thing happened with the water tank: it showed the message “insert tank” and kept blinking on and off.
Now the machine didn’t want to turn on at all. When I pressed the power button, it made a sound and the display lit up, but nothing was shown. After a while, the machine did start working, but then it didn’t respond to any button presses. After some time, the buttons started working again, and it functioned normally, but then suddenly none of the buttons would respond again. At one point, it also decided to start dispensing hot water on its own and then stopped immediately.
My question is whether the control board could be faulty, worn out, or something else. I don’t really believe these errors are caused by sensors, because when the sensors are manually triggered, you can clearly hear a click and the machine responds properly.
Otherwise, the machine itself makes coffee, hot water, and cappuccino normally. Recently, all seals were replaced because it was constantly leaking water.
I couldn’t attach the video here, but it can be watched on YouTube, I know the video is longer than I intended, but I wanted to show everything the machine was doing.
