Billie B-5000 strange behaviour

Turned off the water to fix a tap. After turning it back on Billie will not dispense water even though everything looks normal.

However entering options mode and it all goes weird. Reset power several times to no avail.

came across this one by pure chance. I also did have B5000 which developed the similar issue. My solution was a second hand Quadra Plus unit from the office I worked and the brand new XL tap from the Billi installer whose customer changed their mind in color. All in all cost me $290 to have the much bigger and (hopefully) better system at the kitchen :)

This might be helpful for people who I struggling with this issue. At least it worked for me. I wound the way to poor the water:
1. Hold both blue and red rings
2. Release red or blue (depending on what hot or cold/filtered water you wish to poor)
3. Fill in the glass
4. Release both rings to stop the flow
