Could a failing Drain Pump Assembly cause the WHIRLPOOL WFW6620 to have symptom: Leaking From Bottom?

The drain pump's internal mechanical seal or the volute housing can develop leaks due to the abrasive nature of greywater and debris. When the seal fails, water bypasses the impeller shaft and exits through the motor weep holes, appearing as a leak directly under the center-front of the machine. This is the most common point of failure for floor-level leaks in high-efficiency front-load units.

Could a failing Detergent Dispenser Housing cause the WHIRLPOOL WFW6620 to have symptom: Leaking From Bottom?

On the WFW6620 series, detergent or softener buildup in the Load & Go system can cause a blockage in the siphon tubes. This results in a hydrostatic backup where water entering the dispenser exceeds the drainage rate, overflowing the housing and running down the interior of the front panel to the base. Replacing the housing ensures the flow paths are clear and the internal seals are intact.

Could a failing Door Bellows Seal cause the WHIRLPOOL WFW6620 to have symptom: Leaking From Bottom?

The EPDM rubber gasket is subject to constant flexing and exposure to chemicals, which can lead to stress cracking or micro-tears, particularly at the 6 o'clock position. Physical damage from sharp objects like zippers or bra wires can also puncture the boot. A breach here allows water to leak into the cabinet base during the fill and wash sequences.
