SAMSUNG WASHER WA45T3400 Leaking From Bottom

Drain Pump Assembly

Source 4 identifies this specific part as a common culprit for leaks in the WA45T3400 model. The pump's internal shaft seal or plastic housing can fail over time, resulting in water exiting the pump assembly rather than the drain line. Because the pump is located at the base of the machine, it manifests as a leak coming directly from the bottom.

Water Inlet Hoses

Standard failure mode for all washing machines; if the rubber gaskets inside the hose couplings perish or the hoses develop hairline cracks, water will run down the back of the machine and pool at the bottom. Source 2 highlights this as a primary check for any leakage symptom.

Drain Hose Guide and Clamp

If the drain hose is not inserted to the proper depth (6-8 inches) or the hose holder is missing as per Source 2, the hose can become dislodged during the high-pressure drain cycle. This causes water to splash or backflow, appearing as a leak from the bottom of the unit.
