Abstract

A dishwasher equipped for single-phase alternating current connection, in particular a dishwasher for typical designated use in a household, includes a recirculating pump for wash water and rinse water with which items to be cleaned are acted upon under a spray pressure. A three-phase rotary current motor drives the recirculating pump. An electronically controlled single-phase AC/three-phase rotary current/frequency inverter impresses current on the three-phase rotary current motor.
