Maytag Dishwasher F8 E4 Error
What it means
F8 E4 means the dishwasher has detected water where it shouldn't be โ 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.
The bottom line on the F8 E4 error
F8 E4 means a float switch sensed water in the base, so the machine stopped to head off a leak. On a recent install the real culprit is usually a loose water connection; on an older unit, a clogged filter backing water up. Resetting alone will not help if there is an actual internal leak.
Start cheap: cut power for five minutes, inspect the water connections, clean the drain filter, and confirm the float moves freely. If the code returns or you see water pooled under the dishwasher, that points to a real leak or failed pump โ call Maytag service.

- Fill hose not routed correctly out the rear left of the cabinet

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.
- 5Empty the drip pan and clear the codeMaytag's guidance is to remove any standing water from the drip pan in the base, then press Cancel once to silence the alarm and Cancel again to clear the code before starting a new cycle. Also use only automatic dishwasher detergent โ hand dish soap creates excess suds that can trip the water sensor.
๐งฐ When to call a professional
If F8 E4 returns after resetting power, checking the water connections, cleaning the filter, and confirming the float โ or if you see actual water pooled under the dishwasher โ 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.
