273284 Genuine Dishwasher Drain Hose for Ariston, Whirlpool Dishwashers, Also Listed as C00273284

Water pooling under the dishwasher, or water left in the tub after a cycle, can come down to a split or kinked drain hose. Part 273284 is the genuine drain hose for Ariston and Whirlpool dishwashers, also known by the longer number C00273284. Drain hoses differ in length and end fittings, so check that 273284 or C00273284 appears on your old hose or in your model's parts list.

Dishwasher not draining or leaking from the drain hose?

After each wash and rinse, the drain pump pushes dirty water out through this hose to the sink waste or standpipe. Over time a hose can split near the clamps, crack where it bends, or collect a plug of food scraps and grease. A blocked or kinked hose leaves water in the bottom of the tub and can trigger a draining error, while a split hose leaks under the machine during the pump out. Check the sink waste spigot for blockages too, as it causes the same symptoms.

Replacing the drain hose

Turn the dishwasher off at the wall, unplug it and turn the water off. Slide it out and catch any water in the old hose with a tray. Release the clamp at the pump end, fit the new hose and clamp it firmly. Route it to the sink waste without kinks, with a high loop under the bench, and secure the end so it can't pull out. Run a rinse cycle and check both ends.
