DAU1590941 Genuine Dishwasher Drain Hose for De'Longhi Dishwashers, Outlet Waste Hose Replacement

Waste water leaves the dishwasher through this hose. Genuine part DAU1590941 is numbered with De'Longhi's DAU159 dishwasher parts and runs from the drain pump out to the sink waste or standpipe. Since no models are on file for this hose, compare the end fittings and length of your old hose, and check your dishwasher's model before ordering. Send us the model number if you'd like the fit confirmed.

Dishwasher not draining or leaking from the drain hose?

When the drain hose is split, perished or kinked, waste water either escapes onto the floor under the sink or can't get out at all. Common signs are water left sitting in the bottom of the tub after a cycle, a drain error code, a musty smell, or a puddle near the back of the dishwasher. Hoses are often crushed when the dishwasher is pushed into its cavity. A blocked sink spigot can cause the same symptoms, so check that first.

Replacing the drain hose

Switch off at the wall, turn off the tap and slide the dishwasher out. Put a tray and towel down, as the old hose will hold some water. Undo the clamp at the pump outlet and at the sink spigot, then route the new hose the same way, with a high loop under the bench to stop waste water siphoning back. Run a rinse cycle and check both ends for drips.

Questions about this part

Can I extend a dishwasher drain hose instead?

Extensions add joins that can leak or block, and a hose that's too long can cause drainage problems. Fitting the correct genuine hose avoids that. If your installation genuinely needs extra length, ask us about a suitable extension kit.
