LAUNDRY TREATING APPLIANCE AND METHOD OF DETECTING OVERSUDS

摘要

A method for detecting an oversuds condition that can lead to a suds lock condition in a laundry treating appliance includes determining a baseline fill level prior to introducing wash liquid in the cycle of operation; sampling fill levels of the wash liquid during a wash phase of the cycle of operation while wash liquid is being drained; comparing each sampled fill level to the baseline fill level and determining a difference; continuing to sample fill levels for a predetermined period after the difference equals zero; identifying a minimum fill level for the predetermined period; sampling a final fill level after the predetermined period; calculating a difference between the minimum fill level and the final fill level; and identifying a potential suds lock condition if the difference exceeds a predetermined threshold.
