140000494413 Genuine Water Sump Assembly with Air Trap for Electrolux Dishwashers, Dishwasher Sump Housing

Part 140000494413 is a genuine Electrolux water sump assembly that includes the air trap. The sump is the collection chamber in the base of the dishwasher tub, and the air trap is the chamber that lets the machine sense its water level by trapping a pocket of air for the pressure switch. No models are on file for 140000494413, so compare it with your parts list before ordering.

Leaking sump or water level problems

Because the sump assembly sits at the lowest point of the wash system, any crack or failed seal there shows up as water in the base tray and often trips the leak protection. The air trap side is more subtle. If it's blocked with grease or food, or split, the pressure switch can't read the water level properly. The dishwasher may overfill, underfill, keep topping up, or stop with a fill or level fault even though water is coming in. Clean out the air trap first, and if the housing is damaged or the trouble keeps returning, replace the assembly.

Fitting the sump assembly

Plan for a bit of time on this one. Isolate power and water, remove the filters and lower spray arm, and pull the dishwasher out to reach the base. Photograph every hose, clamp, wire and the pressure switch tube before you disconnect them. Transfer any parts the new assembly doesn't include, use fresh seals where needed, and leak test with a short program before refitting the dishwasher.

Questions about this part

What is the air trap for?

The air trap holds a pocket of air that's compressed as the water level rises. A small tube carries that pressure to the level switch, which tells the dishwasher when to stop filling. Blockages or cracks give false level readings.
