DAU1590971 is a genuine inlet hose assembly for De'Longhi dishwashers, also listed under the number 17476000001321. It carries mains water from the tap to the dishwasher's inlet. No models are on file, so check the number on your old hose or parts list, and look at whether your current hose has a safety valve box at the tap end. Our parts enquiry form can confirm the fit.

Dishwasher leaking at the tap or not filling?

The inlet hose is under mains pressure whenever the tap is on, so it's one of the parts most likely to leak. Rubber perishes, fittings crack and the hose can kink when the dishwasher is pushed back into place. Look for drips at the tap or rear connection, water pooling under the machine, or a dishwasher that fills slowly or shows a water supply error. A kinked or crushed hose restricts the flow, while a split one can flood the floor.
