baumatic intergrated bdw45.1?

when any program is selected the machine drains then all you can hear for the remainder of the cycle is a humming noise, after a few minutes you can hear the tablet draw open but no water whooshing noise is heard, the machine continues with what would be the cycle then stops and the dishes are dirty

all the filters have been checked , there is no error message and the water pressure is fine.

please help1
