Abstract

Provided herein are an appliance and method for washing and rinsing goods. The appliance may include a circulation pump, a sensing arrangement arranged to measure an indication of circulation pump pressure or process water flow rate through the circulation pump, and a controller arranged to control operating speed of the circulation pump. The controller may be further arranged to detect that the indicated circulation pump pressure or process water flow rate through the circulation pump is insufficient, and gradually reduce operating speed of the circulation pump until the circulation pump pressure or the process water flow rate through the circulation pump is at a sufficient operational level.
