Left: Drain Hose leaving the Drain Pump. The Drain
Hose is bracketed in Yellow. From the point where the
Drain Hose leaves the pump (at the Green Arrow) it
should rise above the Wash Pump Inlet Hose (Red
Arrow). Behind the hoses, you can see the Drain
Solenoid Valve and its electrical connections.
Below: Drain Hose under the Washer Tank. Like the
picture to the left, the Green Arrow indicates the
clamped end of the Drain Hose at the Drain Pump.
From this point, the Drain Hose slopes upwards over the
Wash Pump and electrical conduit. There should be no
level places or sumping below the tank as the water in
this hose is used to prime the pump. The Yellow Arrow
shows where a zip tie should be placed to hold the Drain
Hose in place, use the bossing on the Wash Pump/Motor
Assembly.
