Analog Pressure Sensor (Water Level Switch)
This sensor translates the hydrostatic pressure of the water/foam mixture into an electrical frequency. If the diaphragm is compromised or the internal oscillator drifts, it will incorrectly report an 'Su' state to the main PCB by misinterpreting the air density in the pressure tube. Replacing the sensor restores the machine's ability to distinguish between actual water level and foam-induced air turbulence.

TwinDos Care Cleaning Agent
The TwinDos system uses flow meters to calculate detergent dosage; however, if the lines have crystallized detergent buildup, the system may over-dispense to compensate for perceived flow resistance. This cleaning agent flushes the internal suction lines and pumps, ensuring the volumetric dosing remains within the threshold that prevents excess aeration.

Drain Pump Assembly
Mechanical failure or impeller wear in the drain pump prevents the rapid evacuation of 'gray water' before the spin cycle. When the drum accelerates with residual water in the outer tub, it acts as a high-speed whisk, creating an 'Su' condition from a mechanical lack of drainage rather than chemical over-dosing.
