how can i fix my hotpoint aquaris df61 dishwasher?

where the pipe connects on the back, there is a filter, turn water off, disconnect pipe check filter. As pipes making noise, could be air lock, before reconnecting pipe, put end in bucket or sink if it reaches, turn water on very slowly. make sure water comes through. If still no water getting into m/c. probably the water inlet valve faulty, replace
