Description

technical field

[0001] The invention relates to a dishwasher having at least one pumping device for pumping dishwashing solution, the pumping device having at least one pump with a brushless permanent magnet motor. The invention also relates to an electronic controller and a pump. Background technique

[0002] Usually, the pump of the pumping device of the dishwasher is embodied as a shielded pole motor or a synchronous motor. The advantages of shielded pole motors are high pumping rates and a defined direction of rotation. This makes it possible to arrange the outlet tangentially on the pump housing. The problem with using shielded pole motors is that, for the most part, shielded pole motors are "dry running" units, which means expensive sealing measures are required. If the seal cannot be maintained, the pump may fail.

[0003] Synchronous motors, on the other hand, are mostly "wet running" devices, which allow for a simpler mechanical design of the pump, since such ex...
