Could a failing Leak Sensor Assembly cause the SAMSUNG DW80R9950US to have symptom: Error Code Lc Leak?

This component sits in the base drip tray and uses a buoyant float to trigger a microswitch when water is detected. It frequently fails when detergent residue or mineral deposits cause the float to stick in the 'up' position, or when moisture-induced corrosion affects the sensor's electrical resistance. Replacing the sensor resolves persistent LC codes where no physical water is found in the tray.

Could a failing Dishwasher Door Gasket cause the SAMSUNG DW80R9950US to have symptom: Error Code Lc Leak?

The door gasket provides a static seal between the tub and the door assembly; over time, thermal cycling and chemical exposure cause the rubber to lose elasticity or develop micro-tears. If the seal fails, water drips directly into the front of the base tray, immediately triggering the buoyancy sensor. This is the most likely culprit if the error occurs specifically during the high-pressure wash or rinse cycles.

Could a failing Drain Hose Assembly cause the SAMSUNG DW80R9950US to have symptom: Error Code Lc Leak?

The drain hose is subjected to vibratory stress and thermal expansion during every drain cycle, which can lead to fatigue cracks or loose connections at the pump outlet. Because the hose is routed through the lower chassis, any pinhole leak will accumulate fluid in the base pan. This part is a common failure point in high-vibration environments or units where the hose was subjected to excessive tension during installation.
