Pressure sensor calibrating method for washing machine, involves changing liquid level in container over pre-determined time period, and measuring value marginally between phases, where value is equated with highest liquid level below drum

摘要

The method involves changing a liquid level in a lye container over a pre-determined time period, and monitoring the liquid level during the changing of the liquid level. A set of values having an even development is assigned to a phase in which the liquid level is present below a drum. Another set of values having a volatile development is assigned to another phase in which the liquid level is above the liquid level of the former phase. A value is measured marginally between the former phase and the latter phase, where the value is equated with the highest liquid level below the drum. An independent claim is also included for a washing machine comprising a lye container and a movable drum.
