▶ If the display screen says ‘tank overfill’, turn the boiler off and on [the switch is at the back]
▶ If the problem persists, turn off the boiler and turn off the water on the water filter (left pipe on the picture below). Wait for an hour.
▶ Carefully, unscrew the excess water pipe (on the back, left hand side), pull it out into a large container and empty the water.
▶ Put the pipe back on, turn the water in pipe on and turn the machines back on
