【Junk Item】Nescafe Barista HPM9633 SPM9633

Nescafé Barista HPM9633 SPM9633
I received this item as almost unused. It is in beautiful condition, like new.
However, I was looking forward to using it, but it kept showing errors from the beginning, and I was never able to make a single cup.
It does power on.

The maintenance indicator and power button light up red. When I put the coffee tank and other parts back in their normal positions and turn it on again, the power button lights up blue and the espresso button lights up red.
→When I press the espresso button, espresso comes out, and then all lights turn green!
But then the buttons stop working.
→When I unplug the power cord and turn it on, everything lights up.
→When I press the coffee menu button, I hear it operating, and then the power button and maintenance button light up red.
→It repeats this cycle endlessly.

(This might mean that espresso can be made, as I was trying to resolve the error (lol).)

So, sadly, I am listing this as a junk item.
(When I purchased this item, I checked its exterior, but due to being busy, I left a review without checking its functionality.)
Thank you for looking.
All parts are like new.
The box has tears and damage from the beginning.
