Maytag Dishwasher F4E2 Error Code
Circulation pump motor error
What this error means
F4E2 means the main wash circulation pump failed to start or report correct feedback. Dishes stay dirty when wash arms do not pressurize.
How F4E2 is detected
F4E2 on Maytag dishwasher units indicates the drive system did not meet expected performance. Direct-drive washers monitor rotor position with a hall sensor; dryers and dishwashers track motor current draw. When the drum or spray arm fails to turn, the inverter or motor relay shuts down to prevent burned windings. Maytag MDB4949SKZ, Maytag MDB8989SHZ, and similar variants may show this fault after an overloaded tub or a foreign object jam.
Glass shard or seed lodged in the pump impeller is a leading trigger. Start with cancel the cycle and remove standing water with a towel. Rotate the drum or spray arm by hand when powered off—it should move without grinding. Grinding confirms mechanical obstruction; free rotation with repeated F4E2 on light loads suggests hall sensor, motor, or inverter board failure requiring professional diagnosis.
Common causes
- Glass shard or seed lodged in the pump impeller
- Loose pump connector under the tub
- Seized pump bearing from hard water scale
- Control relay not sending voltage to the pump
Step-by-step fixes
- 1Cancel the cycle and remove standing water with a towel
- 2Remove the lower spray arm and filter to inspect the sump
- 3Spin the impeller by hand when power is off—it should turn freely
- 4Restart a normal wash and listen for pump hum in the first two minutes
When to call a technician
Pump hums without water movement or F4E2 with a free impeller requires circulation pump replacement.
Affected models
- Maytag MDB4949SKZ
- Maytag MDB8989SHZ
- Maytag MDB7759AWM
Prevention & maintenance
- Avoid washing single heavy rugs or shoes that bind the drum; distribute weight evenly to reduce motor strain that precedes F4E2.
- Record when F4E2 appears in the cycle and whether it clears after a 60-second power reset on your Maytag dishwasher—that detail speeds diagnosis if you call service.
- Keep the model and serial number from the rating plate when ordering parts for F4E2; Maytag uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting F4E2; reversed plugs on pumps and valves cause immediate repeat faults.
