16. A method for cleaning a water purification apparatus configured to produce purified water, the water purification apparatus including a reverse osmosis device configured to produce a purified fluid flow and a reject fluid flow, the method comprising:
controlling heating of purified fluid in the purified fluid flow downstream from the reverse osmosis device,
re-circulating the heated purified fluid in a first fluid path from a point downstream from a heater to a tank arranged in a feed fluid path upstream from the reverse osmosis device until a first temperature dependent criterion is fulfilled,
re-directing the heated purified fluid to flow in a second fluid path of the water purification apparatus in response to the first temperature dependent criterion being fulfilled, and
controlling heating of the re-directed heated purified fluid such that a second temperature dependent disinfection criterion for the second fluid path is fulfilled.
