Domestic dishwashing machine and method
A household dishwasher includes a dishwasher cavity, a door attached pivotably to the dishwasher cavity, a door opening and closing device for automated opening and closing of the door, and a control unit designed to actuate the door opening and closing device. The control unit is designed to detect a motor current of a drive element of the door opening and closing device and to evaluate the detected motor current as to whether the door opening and closing device is functional or non-functional.
1. A household dishwasher, comprising:
a dishwasher cavity;
a door attached pivotably to the dishwasher cavity;
a door opening and closing device for automated opening and closing of the door; and
a control unit designed to actuate the door opening and closing device, said control unit designed to detect a motor current of a drive element of the door opening and closing device and to evaluate the detected motor current as to whether the door opening and closing device is functional or non-functional.
2. The household dishwasher of claim 1 , wherein the control unit is designed to output a signal and/or to deactivate the door opening and closing device when the door opening and closing device is non-functional.
3. The household dishwasher of claim 1 , wherein the door opening and closing device includes a cable coupled to the door and a spring element coupled to the cable, said control unit designed to evaluate the motor current in order to establish whether at least one of the cable and the spring element is functional or non-functional.
4. The household dishwasher of claim 3 , further comprising a drive roller driven by the drive element, said cable being wrapped around the drive roller and driven by the drive roller.
5. The household dishwasher of claim 1 , wherein the control unit is designed to actuate the drive element in a closed state of the door and to detect and evaluate the motor current in the closed state of the door.
6. The household dishwasher of claim 1 , wherein the control unit is designed to compare a motor characteristic curve of the drive element with at least one member selected from the group consisting of a reference motor characteristic curve stored in the control unit and a limit value stored in the control unit, and to identify, as a function of a deviation of the motor characteristic curve from the member, whether the door opening and closing device is functional or non-functional.
7. The household dishwasher of claim 1 , further comprising a user interface designed to operate the door opening and closing device and to output a signal indicating whether the door opening and closing device is functional or non-functional.
