Could a failing Water Level Pressure Sensor cause the SAMSUNG FRONT LOAD WASHER to have symptom: Error Excess Bubbles?

The pressure sensor translates tub air pressure into an electrical frequency; if the internal diaphragm is fouled by detergent residue or the sensing tube is partially blocked, the sensor sends an incorrect frequency to the PCB. This signal is misinterpreted by the control board as 'high foam density' (Sud error), even if no bubbles are visible. Replacing this sensor ensures the control board receives accurate data regarding the air-to-water ratio inside the drum.

Could a failing Drain Pump Debris Filter cause the SAMSUNG FRONT LOAD WASHER to have symptom: Error Excess Bubbles?

A clogged debris filter prevents the efficient evacuation of soapy water, leading to a high concentration of surfactants remaining in the tub during the rinse phase. This residual soap re-activates into foam during high-speed agitation, triggering the Sud error repeatedly. If the filter seal is degraded or the plastic cage is warped, a replacement is necessary to ensure proper drainage flow rates.

The 'Sud' error is a programmed safety feature designed to pause the wash cycle to allow excessive foam to collapse. This prevents the suds from entering the pressure sensor tube or overflowing the detergent drawer, which could damage electronic components.
