4055978334 Genuine Float Assembly for Electrolux Group Dishwashers, Replacement Dishwasher Float Part

This genuine Electrolux float assembly, part 4055978334, is filed with our Electrolux group dishwasher parts. Electrolux's own description is just 'float, assembly', so it doesn't spell out whether it's a water level float or a flood protection float. Compare the shape and the number on your old float before ordering, or send us your model and product number and we'll check the fit for you.

How a dishwasher float works and the faults it causes

Floats are simple parts with an important job. As water rises, the float lifts and works a switch, telling the control board how much water is there or that water has reached somewhere it shouldn't. In many dishwashers a float in the base tray acts as flood protection, stopping the fill and running the drain pump if a leak is detected. A stuck, cracked or missing float can leave the machine refusing to fill, filling too much, showing a flood or water fault, or pumping out non-stop.

Checking and replacing the float

Turn the dishwasher off at the wall and turn off the tap before you start. If the float sits in the base tray, look for water underneath first, as a leak may have tripped it and will need fixing too. Clean away any grease or debris, fit the new float so it moves freely up and down, then run a short program to test.

Questions about this part

My dishwasher keeps pumping out. Is the float to blame?

It might be. A float stuck in the raised position can make the machine think it's flooding. Check the base tray for water and a leak first. If the float itself is damaged or sticking and your old part reads 4055978334, this is the matching replacement.
