Method for operating a washing machine, and washing machine

The washing machine control device dynamically adjusts the spin cycle parameters based on the detected load quantity. For large or bulky loads, the system executes a spin cycle at maximum speed (e.g., 1000-1500 rpm) after rinsing to forcefully displace laundry from the door area. For small loads, the system applies water directly to flush foam without requiring a high-speed spin cycle. This dynamic adaptation resolves the contradiction by making the foam removal method effective across all load quantities.

The system changes operational parameters (spin speed, water application timing) based on load detection. The control device detects load quantity and type, then modifies the washing program parameters accordingly. For bulky or large loads, it increases spin speed to maximum and delays water application until after spinning. For small loads, it applies water immediately after rinsing at normal spin speeds. This parameter adjustment ensures effective foam removal regardless of load size.

The system dynamically determines whether to execute a maximum speed spin cycle based on load detection. Only when large or bulky loads are detected does the system proceed to high-speed spinning followed by water application. For small loads, it skips the maximum speed spin cycle and applies water directly after rinsing. This conditional execution eliminates unnecessary energy consumption while maintaining effective foam removal when needed.

The system uses a brief, intensive maximum speed spin cycle only when absolutely necessary (large/bulky loads), rather than maintaining continuous high-speed operation. The spin cycle lasts only long enough to achieve the required laundry displacement, then transitions to water application. This temporary, targeted use of high energy consumption resolves the contradiction by limiting energy use to only when it provides necessary foam removal benefit.

The system performs a preliminary spin cycle at maximum speed before applying water to the door sight glass and seal. This preliminary action forcefully displaces laundry away from the door area, ensuring that when water is subsequently applied for foam flushing, it directly contacts the foam on the door components rather than being absorbed by nearby laundry. This preliminary displacement action guarantees consistent foam removal reliability across different load types.

The maximum speed spin cycle serves as a preliminary anti-action that prevents the harmful effect of water absorption by laundry. By spinning at maximum speed before water application, the system preemptively removes laundry from the door vicinity, thereby preventing the potential harm of water being absorbed instead of flushing foam. This anticipatory measure ensures reliable foam removal regardless of load characteristics.
