Maytag Dishwasher F8 E4 Error
What it means
F8 E4 means the dishwasher has detected water where it shouldn't be — typically in the base or drip pan beneath the tub. A float switch in the bottom of the unit senses excess water and trips this code, and the dishwasher stops to prevent a leak. On a recently installed machine it's often a loose or improperly seated water connection; on an older one it usually points to a clogged filter that backs water up, or a small internal leak.
Common causes of the F8 E4 error
- Loose or improperly seated water-supply connection on a newly installed unit
- Fill hose not routed correctly out the rear left of the cabinet
- Clogged drain filter backing water up into the base
- Float switch stuck or disconnected
- Small internal leak from a hose, seal, or the pump
- Temporary control glitch
How to fix the Maytag Dishwasher F8 E4 error
- 1Reset the dishwasherDisconnect power (unplug it or switch off its breaker) for at least 5 minutes, then restore power. This clears the code if it was a one-time glitch.
- 2Check connections on a newly installed unitIf the dishwasher was recently installed, inspect every water connection point and confirm the rubber washer is properly seated in each fitting. Make sure the fill hose is routed out the rear left side of the unit as specified.
- 3Clean the drain filterRemove and rinse the filter assembly at the bottom of the tub. A filter clogged with food debris blocks drainage and lets water overflow into the drip pan, tripping the float and the F8 E4 code.
- 4Confirm the float switch is connectedMake sure the float switch in the base is seated and free to move, and that its connection isn't loose, so it isn't falsely reading water in the pan.
🧰 When to call a professional
If F8 E4 returns after resetting power, checking the water connections, cleaning the filter, and confirming the float — or if you see actual water pooled under the dishwasher — there is likely an internal leak or a failed float/pump. Locating an internal leak means removing panels and accessing the base, so call Maytag service or a qualified technician.

What does F8 E4 mean on a Maytag dishwasher?
F8 E4 means the dishwasher detected water in an unintended area, such as the base or drip pan. A float switch trips the code and the machine stops to prevent a leak.
How do I fix the F8 E4 error?
Reset power for 5 minutes, then check water connections (especially on a new install), clean the drain filter, and confirm the float switch is seated. Many F8 E4 codes clear after these steps.

Not always. On a new install it's often a loose connection, and on an older unit a clogged filter. But if it returns or you see water under the dishwasher, there may be a real leak that needs service.
