13. 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, via a control unit, heating of purified fluid produced by the reverse osmosis device downstream from the reverse osmosis device;
directing, via the control unit, the heated purified fluid in a first fluid path through a polisher device;
re-directing, via the control unit, the heated purified fluid into a second fluid path to bypass the polisher device in response to a first temperature dependent disinfection criterion for the polisher device being fulfilled, and
controlling, via the control unit, heating of the re-directed purified fluid in order to fulfill a second temperature dependent disinfection criterion for the second fluid path.
