use cino xs Presso-Bean E2 with water tank

Hello,

first of all, I wish everyone a happy new year.

I bought a used "cino xs presso bean E2" coffee machine.
The machine has been converted to operate with direct water connection. I would like to use the coffee machine now with a water tank.
This means that the machine not only has to open the inlet valve for the water supply for a short time, but a pump has to draw the water from a tank.
Can I easily retrofit the vending machine or is a special kit necessary for this? Are there any instructions?

I would be pleased if you could help me further.

Many thanks and kind regardsNatalia

Hi,

is the problem still there, I had once rebuilt about 6 years ago.
That was described in some manual.
Should I look if I can still find?
