Drain Pump Cover (Suction Cap)
The drain pump in this unit is a centrifugal design that requires a sealed volute to function. If this plastic cover is missing, loose, or cracked, the impeller cannot create the suction needed to pull water from the sump and push it through the check valve. This results in the pump motor spinning (audible) but no water being displaced.

Drain Pump
Internal electrical failure of the synchronous motor or a sheared impeller shaft will prevent the mechanical transfer of water. Over time, the seals on the pump motor can fail, allowing moisture into the windings, which leads to torque loss and the inability to overcome the weight of the water column in the drain hose.

Drain Hose
The corrugated geometry of the OEM hose is prone to accumulating lipid-based clogs and calcium deposits which increase fluid friction. If the internal diameter is restricted or the hose is kinked during installation, the pump's maximum head pressure will be exceeded, causing the system to time out and leave standing water in the basin.
