4055944369 Genuine Pressure Switch Hose, 5m Bag, for Electrolux Washing Machines and Dishwashers, Also Listed as W019

Electrolux part 4055944369 is a 5 metre bag of genuine pressure switch hose, also listed as W019. This is the thin air tube that runs from the air chamber at the bottom of the tub to the water level pressure switch. Cut it to length to replace a split, perished or blocked tube, with plenty left over for future repairs. Check the bore matches your existing hose and its fittings before ordering.

Washer overfilling, not filling or showing a level error?

As water fills the tub, it traps air in the chamber and pushes pressure up the hose to the pressure switch, which tells the controls when the right level is reached. A cracked, kinked, loose or blocked hose breaks that signal. The machine may overfill and leak, keep filling without stopping, refuse to start the wash, or show a water level error. Dishwashers that use a pressure switch suffer the same faults. Once the old hose is off, blowing gently through it often reveals a blockage or split, and soap scum near the chamber end is a common cause.

Fitting new pressure hose

Switch the machine off at the wall and turn off the taps. Remove the top or back panel to reach the pressure switch. Cut a new length to match the old hose, avoiding sharp bends or kinks in the route, and push it fully onto both nipples. Use the original clips or ties to hold it in place, then run a fill to confirm the machine stops at the correct level.
