Bosch DW does not fill or drain properly

:(I have cheched the drain hose to the disposal and made sure it has the loop required. The wash motor starts but stops after a small amt of water enters. The I force the water to drain with the two cancel drail buttons. I can hear the motor start but it wont drain. I manually drain it with a small shop vac. What do i do now? I down loaded the trouble shooting manual posted by someone earlier. Do I need a New drain pump. Clean it? New water valveterminal or level switch? Circulation pump? Flow switch? HELP PLEASE!

This is a duplicated thread.
