         3 . The dispensing system according to  claim 1 , wherein the preparation in the first chamber has a pH value of 3-7, the preparation in the second chamber has a pH value of 6-8 and the preparation in the third chamber has a pH value of 6-8 or a pH value of 1-3. 
     
     
         4 . The dispensing system according to  claim 1 , wherein the preparation in the first chamber has a pH value of 3-7, the preparation in the second chamber has a pH value of 8-12 and the preparation in the third chamber has a pH value of 6-8 or a pH value of 1-3. 
     
     
         5 . The dispensing system according to any one of the preceding claims, wherein the preparation in the first chamber has a pH value of 6-8, the preparation in the second chamber has a pH value of 8-12 and the preparation in the third chamber has a pH value of 6-8 or a pH value of 1-3. 
     
     
         6 . The dispensing system according to  claim 1 , wherein the first chamber does not contain any protease and/or scent. 
     
     
         7 . The dispensing system according to  claim 1 , wherein the second chamber does not contain any enzyme selected from the group of amylases, mannanases, cellulases, lipases and/or pectate lyases and/or scent. 
     
     
         8 . The dispensing system according to  claim 1 , wherein the third chamber does not contain any enzymes. 
     
     
         9 . The dispensing system according to  claim 1 , wherein the dispenser comprises at least one sensor for detecting the presence of water during operation of the washing machine. 
     
     
         10 . The dispensing system according to  claim 1 , wherein the dispenser comprises at least one conductivity sensor and/or temperature sensor and/or acoustic sensor. 
     
     
         11 . The dispensing system according to  claim 1 , wherein the dispenser is configured such that dispensing from the first cartridge chamber occurs in the presence of at least one sensor signal which represents the presence of water in the interior of the washing machine. 
     
     
         12 . The dispensing system according to  claim 1 , wherein the dispenser is configured such that dispensing from the second chamber is triggered after a predefined time of between 0.1 s and 30 min after dispensing from the first cartridge chamber has taken place. 
     
     
         13 . The dispensing system according to  claim 1 , wherein the dispenser is arranged detachably or fixedly outside the washing machine. 
     
     
         14 . The dispensing system according to  claim 1 , wherein the washing machine comprises a rotating treatment compartment and wherein the dispenser is arranged detachably or fixedly inside the rotating treatment compartment. 
     
     
         15 . The dispensing system according to  claim 1 , wherein the washing machine comprises a dispensing drawer and wherein the dispenser is arranged detachably or fixedly inside the dispensing drawer. 
     
     
         16 . A cartridge for use in a dispensing system according to  claim 1 , in which the cartridge comprises at least three chambers, which contain different flowable preparations, in which
 the first chamber stores at least one enzyme selected from the group of amylases, mannanases, cellulases, lipases and/or pectate lyases and at least one surfactant and/or complexing agent at a pH value of 6-8,   the second chamber stores at least one protease and at least one surfactant and/or complexing agent at a pH value of 6-8,   the third chamber stores at least one scent and/or one optical brightener, at a pH value of 6-8.   
     
     
         17 . A method for releasing preparations in the interior of a washing machine, comprising
 at least one dispenser with at least one sensor, which is suitable for detecting the presence of water in the interior of the washing machine and   at least one cartridge couplable to the dispenser,
 in which the cartridge comprises at least three chambers, which contain different flowable preparations, in which
 the first chamber stores at least one enzyme selected from the group of amylases, mannanases, cellulases, lipases and/or pectate lyases and at least one surfactant and/or complexing agent at a pH value of 6-8, 
 the second chamber stores at least one protease and at least one surfactant and/or complexing agent at a pH value of 6-8, 
 the third chamber stores at least one scent and/or one optical brightener, at a pH value of 6-8, 
 
   
       wherein
 dispensing from the first cartridge chamber occurs in the presence of at least one sensor signal which represents the presence of water in the interior of the washing machine, and 
 dispensing from the second chamber is triggered after a predefined time of between 0.1 s and 30 min, after dispensing from the first cartridge chamber has taken place.
