The invention is an improvement to a multi-dosing detergent delivery device, the device being of a type comprising a housing (2) for receiving therein, in use, a cartridge (200) having a plurality X of chambers (210) each accommodating a detergent composition, a directing means (3, 34) to direct, in use, wash liquor selectively into a selected chamber (210) of the cartridge (200) to contact the detergent composition therein, an outlet to allow the detergent loaded wash liquor to exit the device and indexing means (100) for automatic movement of said cartridge (200) in use relative to said directing means (3, 34). The specific improvement to the device comprises ensuring that the entry hole (220) of a selected chamber is out of alignment with a hole (34) forming part of the directing means at the start of a heating cycle of a wash, so as to avoid or reduce a problem of detergent held within the chamber (210) from being washed out or diluted during a pre-wash cycle of a dishwasher. In particularly preferred arrangements the gearing of the indexing means of the device is arranged to zero the amount of offset at the end of the heating up cycle.
