4055409843 Genuine Detergent Circulation Hose CW for Electrolux Group Washing Appliances, Internal Wash System Hose

Described as a detergent circulation hose marked CW, genuine part 4055409843 is an internal hose from an Electrolux group washing appliance. Hoses like this carry wash water and dissolved detergent between the dispenser, sump and circulation pump. Our records don't confirm the appliance or a model list, so the number is the key. Check it against the label or moulding on your old hose, or send your machine's model and PNC.

Leaks and poor wash results from a split hose

Inside a washing appliance, shaped rubber hoses link the detergent dispenser, the tub or sump and the pumps. Water and detergent are pushed through them under pressure many times each cycle. With age the rubber hardens and cracks, especially at the bends and clamp points, and lint or detergent sludge can block it. Signs include water under the machine, a dispenser that doesn't empty properly, detergent left behind after the wash, and loads that don't come out clean. Check the clamps for looseness before blaming the hose.

Swapping the hose

Switch off at the wall and turn off the water taps. Drain as much water as you can, then lay towels down, because hoses always hold some. Photograph the hose route and clamp positions before removing it. Push the new hose fully onto each spigot and refit the clamps in the same place. Run a short cycle and check every joint for drips.

Questions about this part

Will a universal hose do the same job?

Usually not. Internal hoses are moulded to follow a set route and fit particular spigot sizes, and a straight hose can kink or rub through. A genuine hose matched by number keeps the original shape and fit.
