A dishwasher comprising:
- a washing chamber with a spray system for subjecting washing stock to washing liquid;
- a washing liquid inflow;
- a water treatment device comprising:
- a reverse osmosis device with a raw water supply line;
- a pure water discharge line;
- a concentrate outflow, the raw water supply line being connectable to a mixing device, the mixing device being configured to set a mixing temperature of the raw water delivered to the reverse osmosis device;
- and a hot water inflow and a cold water inflow, the washing liquid inflow being connectable to the pure water discharge line of the reverse osmosis device,
- a heating device configured to heat the washing liquid being supplied, the heating device comprising a boiler having a boiler heat exchanger that is connectable to the hot water inflow of the reverse osmosis device such that the boiler heat exchanger is configured to heat water supplied to the hot water inflow;
- and
- a tank configured to partially collect the washing liquid, the tank having a tank heat exchanger that is connectable to the hot water inflow of the reverse osmosis device such that the tank heat exchanger is configured to heat water supplied to the hot water inflow.
