diverter valve?

There is one inlet port, marked with a line, and two outlet ports.
The inlet port connects to the pump, one of the outlet ports goes to drain and the other to the recirculation hose ( goes to the top of the tank ). To test for the outlet port to drain, blow through the inlet port and the air should go out of the port to drain. The other closed port goes to recirculation and opens when the flap is operated by the brown electrical motor attached to the unit.
