A milking system includes a milking member for extracting milk from an animal, a transport line, a milk tank, a milk filter unit for filtering the milk with a first filter device and a second filter device, each including a filter container and a filter element, and a valve arrangement to convey milk through the devices, where the valve arrangement communicates with a control unit. The milking system further includes an indication device generating an indication to a user when any one of the filter elements needs to be replaced, which filter of the first and second filter device needs to be replaced, and when the filter element indicated to need to be replaced is accessible for replacement. A method for operating and cleaning the milking system is also provided.

1. A milking system comprising: a milking member (M) for extracting milk from an animal;a transport line (1) connected to the milking member (M);a milk tank (2) connected to the transport line (1), the milk tank receiving the milk from the milking member (M) via the transport line (1);a milk filter unit (3) forming a part of the transport line (1), the milk filter unit (3) filtering the milk and comprising at least a first filter device (4) and a second filter device (5), each filter device (4, 5) comprising a filter container (6) and a filter element (7);a valve arrangement configured to convey the milk through at least one of the first filter device (4) and the second filter device (5);a control unit (9) configured to control the valve arrangement, the valve arrangement in communication with the control unit (9); andan indication device (10) operatively connected to the control unit (9), the indication device (10) generating an indication to a user i) when any one of the filter element (7) of the first filter device (4) and the second filter device (5) needs to be replaced, ii) which filter element (7) of the first filter device (4) and the second filter device (5) needs to be replaced, and iii) when the filter element (7) indicated to need to be replaced is accessible for replacement, wherein,each filter device (4, 5) comprises a mechanical lock (17) configured to permit and prevent opening of each filter container (6), in order to control access to the filter element (7) contained in the filter container (6), the mechanical lock (17) operatively connected to the control unit (9) and the indication device (10), andthe indication device (10) communicates with the mechanical lock (17) to permit opening of the filter container (6) when said indication device (10) indicates that the filter element (7) is accessible for replacement. 2. The milking system according to claim 1, wherein said indication device (10) is further configured to generate said indication in response to a valve position of the valve arrangement. 3. The milking system according to claim 1, wherein said indication device (10) is further configured to generate a further indication to the user that the filter element (7) is not accessible for replacement. 4. The milking system according to claim 1, wherein said indication device (10) is further configured to generate an indication to the user that the filter element (7) has been replaced. 5. The milking system according to claim 1, wherein said indication device (10) comprises a sensor device (11) configured to sense a value of at least one parameter related to a condition of each filter element (7). 6. The milking system according to claim 5, wherein the parameter is at least one of i) time of use of the filter element (7), ii) light absorption characteristics of the filter element (7), iii) a pressure difference over the filter element (7), and iv) an amount of milk that has passed through the filter element (7). 7. The milking system according to claim 5, wherein the indication device (10) is configured to generate said indication in response to a threshold level of the value sensed by the sensor. 8. The milking system according to claim 1, wherein the indication device (10) comprises a user panel (12) in proximity of the filter unit (3). 9. A method for operating a milking system comprising: operating a milking member (M) to extract milk from an animal, wherein a transport line (1) is connected to the milking member (M), a milk tank (2) connected to the transport line (1), and the milk tank receives the milk from the milking member (M) via the transport line (1);filtering the extracted milk by operating a milk filter unit (3) forming a part of the transport line (1), the milk filter unit (3) comprising at least a first filter device (4) and a second filter device (5), each filter device (4, 5) comprising a filter container (6) and a filter element (7), with a valve arrangement configured to convey the milk through at least one of the first filter device (4) and the second filter device, the filtering milk step comprising conveying the milk through at least one of the first filter device (4) and the second filter device (5); andthrough i) a control unit (9) configured to control the valve arrangement, the valve arrangement in communication with the control unit (9), and ii) an indication device (10) operatively connected to the control unit (9), operating the indication device (10) to generate an indication to a user i) when any one of the filter element (7) of the first filter device (4) and the second filter device (5) needs to be replaced, ii) which filter element (7) of the first filter device (4) and the second filter device (5) needs to be replaced, and iii) when the filter element (7) indicated to need to be replaced is accessible for replacement; andoperating the indication device (10) to communicate with a mechanical lock (17) to permit opening of the filter container (6) when said indication device (10) indicates that the filter element (7) is accessible for replacement, wherein the mechanical lock (17) is configured to permit and prevent opening of each filter container (6), in order to control access to the filter element (7) contained in the filter container (6), the mechanical lock (17) operatively connected to the control unit (9) and the indication device (10). 10. The method according to claim 9, wherein said generating an indication step includes a further indication that the filter element (7) has been replaced. 11. The method according to claim 9, wherein said generating an indication step includes a further indication that the filter element (7) is not accessible for replacement. 12. The method according to claim 9, wherein the method comprises the further steps of: using a sensor to sense a value of at least one parameter related to a condition of the filter element (7), andgenerating said indication in response to at least the value sensed by the sensor. 13. The method according to claim 9, comprising the further steps of: operating a cleaning equipment (8) connected to the transport line (1) and configured to provide a rinsing liquid and a cleaning liquid during a cleaning operation through the transport line (1), wherein the valve arrangement is also configured to convey the rinsing liquid and the cleaning liquid through at least one of the first filter device (4) and the second filter device (5):supplying the rinsing liquid through the milk filter unit (3) and the first filter device (4) during a pre-rinsing phase;supplying the cleaning liquid through the milk filter unit (3) during a cleaning phase; andsupplying the rinsing liquid through the milk filter unit (3) during an after-rinsing phase,wherein the cleaning liquid, during the cleaning phase, is supplied through the first filter device (4) during a minor time period of the cleaning phase and through the second filter device (5) during a major time period of the cleaning phase. 14.
