Method for operating a water-conducting domestic appliance

A method for operating a water-conducting domestic appliance with a circulating pump and a water flow diverter which is associated with the circulating pump and has at least one control element configured for adjustment by a control element motor for changing a direction of flow of a liquid through the water flow diverter, the method comprising:

• filling the water-conducting domestic appliance with a minimum quantity of filling water to be circulated by the circulating pump,
• in a first step, checking the water flow diverter for malfunctions, and
• in a second step, performing a first true running check to check whether the minimum quantity of filling water corresponds at least a setpoint quantity of filling water required to ensure true running of the circulating pump,
• evaluating for the first true running check at least one operational parameter of an electric motor driving the circulating pump to ascertain whether the circulating pump is running true,
• performing a second true running check or a refilling step for increasing the minimum quantity of filling water when the water flow diverter is not malfunctioning, and
• omitting the second true running check or the refilling step when the water flow diverter is malfunctioning.

A water-conducting domestic appliance, comprising:

• a circulating pump circulating a minimum quantity of filling water filled in the water-conducting domestic appliance,
• an electric motor driving the circulating pump,
• a water flow diverter associated with the circulating pump,
• at least one control element constructed to change a direction of flow of a liquid through the water flow diverter,
• a control element motor for adjusting the at least one control element, and
• a device having a first unit for detecting a malfunction of the water flow diverter and a second unit for performing a first true running check of the circulating pump,
• wherein the second unit checks whether the minimum quantity of filling water in the water-conducting domestic appliance corresponds at least to a setpoint quantity of filling water required to ensure the true running of the circulating pump, and wherein the second unit evaluates at least one operational parameter of the electric motor driving the circulating pump to ascertain whether the at least one operational parameter corresponds to true running of the circulating pump, wherein when the first unit fails to detect a malfunction of the water flow diverter, a second true running check or a refilling step for increasing the minimum quantity of filling water is performed, and wherein when the first unit detects a malfunction of the water flow diverter, the second true running check or the refilling step is omitted.
