GE Dishwasher Flood Stem (WD21X22838)

The GE Dishwasher Flood Stem is a small internal float component that helps monitor and control the water level inside your dishwasher. It works alongside the float assembly to signal the water inlet valve to stop filling once the water reaches the correct level, helping prevent overfilling or flooding on the floor.

The GE Dishwasher Flood Stem can wear out or break over time due to repeated contact with hard water minerals, detergent buildup, or simple physical wear from regular use. If the stem becomes stuck, cracked, or fails to move freely, the float switch may no longer read the water level correctly, which can lead to water control problems during the wash cycle.

Watch for these symptoms to help determine if the flood stem is the cause of your dishwasher trouble:

- Dishwasher overfills with water before or during the wash cycle

- Water leaking onto the floor from the base of the dishwasher

- Dishwasher stops filling before reaching the correct water level

- Float assembly does not move up and down freely

- Dishwasher runs but dishes come out poorly cleaned due to low water

- Visible cracks, damage, or buildup on the float stem component
