• an electrolysis body disposed in the water reservoir comprising:
• a) a pair of electrodes made of a conductive material suitable for providing electrolysis,
• b) conductors for conducting current to the electrodes,
• c) an insert unit having a first side and a second side opposite each other, wherein the first side faces out of the water reservoir when the insert unit is placed in position in the water reservoir in use for water disinfection and the second side faces into the volume of the water reservoir when placed in position in the water reservoir in use for water disinfection,
• wherein
• (i) the pair of electrodes is arranged and fixed in the insert unit and protrude from the second side,
