Water level determination for laundry washing machine

A laundry washing machine in which a suitable level of water is automatically determined for any particular load size. The machine is operated to first determine an initial estimation of the clothes load and to then fill to a water level suitable to the initial load estimation. The machine is then operated in such a way to check if the estimated water level is actually sufficient for the clothes load, essentially by determining the resulting load on the laundry machine motor. If the water level is found to be insufficient, then more water is added before the checking routine is carried out once again. When the water level is determined to be suitable for the clothes load, washing is commenced.
