A method for preventing wash liquor foam inhibiting pump performance in a horizontal drum automatic washing machine has a foam detector controlling the drive motor for the drum

摘要

At the end of the load distribution phase (A) the water level (P) falls at a rate determined by the amount of residual foam with the drum stationary (B) as the rate is measured at time intervals (t2-t7) as the foam is reduced until the drive motor resumes an interrupted spin speed (N).
