Abstract

A dishwasher, including: a washing container; at least two spray devices disposed inside the washing container; a circulating pump to deliver liquid to the at least two spray devices; a first drive to drive the circulating pump; a reversing device, wherein, based on a position of the reversing device, the circulating pump delivers the liquid to at least one of the at least two spray devices; and a control device to detect a current position of the reversing device based on an operating parameter assigned to the first drive and to at least one of control and regulate the first drive.

Claims (14)

1. A dishwasher, comprising:

a washing container;

at least two spray devices disposed inside the washing container;

a circulating pump to deliver liquid to the at least two spray devices;

a first drive to drive the circulating pump;

a reversing device, wherein, based on a position of the reversing device, the circulating pump delivers the liquid to at least one of the at least two spray devices; and

a control device to detect a current position of the reversing device based on an operating parameter assigned to the first drive and to at least one of control and regulate the first drive.

2. The dishwasher of claim 1 , wherein the operating parameter is a load magnitude of the circulating pump.

3. The dishwasher of claim 1 , wherein the first drive is a first electric drive and wherein the operating parameter is at least one of an electric current, an electric voltage, an electric power output, a torque, and a rotational speed of the first electric drive.

4. The dishwasher of claim 3 , wherein the control device is structured, based on the operating parameter of the first electric drive, to at least one of control and regulate the first electric drive.

5. The dishwasher of claim 1 , further comprising a second drive to adjust the reversing device.

6. The dishwasher of claim 5 , wherein the second drive is a second electric drive.

7. The dishwasher of claim 1 , wherein the control device is configured to adjust the reversing device until the control device detects, based on the operating parameter, that the reversing device has assumed a desired position.

8. The dishwasher of claim 1 , wherein the control device is configured to compare the operating parameter with comparative values assigned to respective individual positions of the reversing device in order to detect the current position of the reversing device based on the operating parameter.
