Abstract

A method for operating a dishwasher that has 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; and a reversing device; wherein, based on a position of the reversing device, the circulating pump delivers the liquid to one or both of the two spray devices. The method includes adjusting the position of the reversing device and detecting the current position of the reversing device based on an operating parameter assigned to the first drive.

Claims (10)

1. A method for operating a dishwasher having 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 two spray devices, the method comprising:

adjusting the position of the reversing device; and

detecting a current position of the reversing device based on an operating parameter assigned to the first drive.

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

3. The method 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 method as claimed in claim 3 , further comprising at least one of controlling and regulating the first electric drive based on the operating parameter of the first electric drive.

5. The method of claim 1 , further comprising adjusting the reversing device by a second drive.

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

7. The method of claim 1 , further comprising adjusting the reversing device until detecting, based on the operating parameter, that the reversing device has assumed a desired position.

8. The method of claim 1 , wherein during the adjusting of the reversing device, the operating parameter is compared 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.
