l have just put a dishwasher in and the drain hose as well as the washine machine waste pipe are connected to a downpipe with auxiliary connections for each appliance,this downpipe is just before the u bend under the sink.The problem is when the dishwasher has been through it,s cycle and finished there is still water at the bottom, l have checked the filter and this is not blocked.What could cause this,the drains are fine and have no blockage.

How deep?

How long is the drain hose?

Is this a new d/wr?

Why isn't this an "appliance" question (look at some of the others)?
Read the installation section of the manual.

Bet the waste pipe is not as indicated in the manual.

2 different angles if we rule out faulty appliance. either the diswasher waste is very long at high level & a lot of water is falling back into the dishwasher sump or the connection to the waste system is under the sink & the dishwasher waste is not high enough before it is attached so when the sink is discharged it runs back into the dishwasher sump. COULD be neither but u can see it not us.
