Abstract

A method and corresponding appliance for carrying out the method may include detecting insufficient circulation pump pressure or process water flow rate through a circulation pump of the appliance, supplying water to a compartment of the appliance and logging a time period during which the water is supplied to the compartment and increasing the speed of the circulation pump to a target pump speed where the circulation pump pressure or the process water flow rate through the circulation pump has reached a sufficient operational level. The method may include logging at least two circulation pump speeds and a time period during which the water is supplied to the compartment, and estimating the water fill rate based on predetermined difference in compartment process water volume for the logged at least two speeds and the water supply time period.
