What F6E4 Means
Maytag gives the potential cause of F6E4 as the water float switch, and names levelling the dishwasher as part of the remedy. The float is an overfill safety: it rises with the water in the tub and tells the control to stop filling. A machine that sits out of level puts water to one side of the tub and can lift the float when the level is actually normal.
Common Causes of F6E4
- Dishwasher out of level in its cabinet
- Debris around the float holding it up
- Float or float switch failed
- Genuine overfill from a fill valve not closing
🔧 One Safe Check You Can Try
Check that the dishwasher sits level - a small spirit level across the bottom of the tub, front to back and side to side, will show it. If it rocks or leans, the levelling feet can be adjusted, which is the step Maytag names. Then look into the sump for anything sitting around the float that could be holding it up, such as a broken glass fragment or a label washed off a jar. Reset the control by cutting power for thirty seconds - unplug the dishwasher if it is on an outlet, or switch off its breaker if it is hard-wired - then restore power and run a short cycle.
⚠ Why You Shouldn't Go Further Than That
- The float switch itself is under the tub base on mains wiring.
- If you can see water under the machine rather than in the tub, turn off the supply and stop using it until it has been looked at.
