Abstract
A method and an electronic control unit for determining and optionally displaying the remaining time in a treatment program in a household appliance include superposing an initializing test program segment on the treatment programs in order to determine an "installed heating capacity" parameter that determines a gradient. To that end, a defined quantity of the medium is heated with an electrical heater for a predetermined period of time. The "installed heating capacity" parameter and/or a comparison value corresponding to its magnitude is calculated from the attained temperature increase, the defined quantity of the medium and the known period of time and is stored as an operand in a nonvolatile memory for later remaining-time determinations.
