Our appliances are supplied with a security device to protect against the return of dirty water back into the appliance. If the spigot of your sink has a "no return valve" incorporated this can prevent the correct draining of your appliance. We therefore advise you to remove it.
When connecting the drain hose to an under sink trap spigot, the entire plastic membrane (A) must be removed. Failure to remove all the membrane will result in food particles building up over time eventually blocking the appliance drain hose spigot.
