Claims5
A method of controlling the operation of a steam generator in a fabric treatment appliance, the method comprising:
- operating the steam generator in an initial phase where the steam generator is brought up to a temperature sufficient to generate steam;
- after the initial phase, operating the steam generator in a steam generation phase where steam is generated;
- comparing a rate of temperature change of the steam generator to a first predetermined value prior to and during the steam generation phase of the steam generator;
- comparing the rate of temperature change of the steam generator to a second predetermined value lower than the first predetermined value only during the steam generation phase of the steam generator;
- and
- controlling the operation of the steam generator based on at least one of the comparisons.
