Maytag Dryer F07 Error Code
Moisture sensor shorted
What this error means
F07 is the opposite of F04—the moisture sensor circuit reads a short. Auto-dry may end immediately or not advance because the board sees constant wetness.
How F07 is detected
When F07 appears on a Maytag dryer, the control board has confirmed that water did not leave the machine within the programmed drain window. On Maytag MEDC465HW, Maytag MEDB855DC, and similar variants, the drain pump runs for a fixed interval—often three to seven minutes on washers and dishwashers—while a pressure switch or turbidity sensor verifies the tub or sump is empty. If water remains, the cycle stops to prevent spin with a full tub or overflow on the next fill.
Most F07 calls are resolved without parts: clean and dry the moisture bars inside the drum. Restricted drain paths mimic pump failure because the impeller spins against a blocked hose or filter. Document whether the pump hums audibly during the drain step; a humming pump with no water movement points to a clogged filter or kinked hose, while silence may indicate a failed pump motor or loose wiring at the harness.
After clearing blockages, run a short cycle and listen at the drain hose for steady water flow. If F07 returns on the next load with a clean filter and straight hose, measure resistance at the pump motor connector per the service manual for your model before ordering a replacement pump assembly.
Common causes
- Metal debris bridging the two sensor bars
- Water splash on the sensor harness during cleaning
- Shorted wires where harness rubs the cabinet
- Failed sensor strip with internal short
Step-by-step fixes
- 1Clean and dry the moisture bars inside the drum
- 2Inspect the harness behind the bulkhead for pinched insulation
- 3Disconnect the sensor plug and measure for short to ground
- 4Run a timed dry instead of auto-dry until repaired
When to call a technician
Open sensor circuit tests good but F07 remains with the harness disconnected—replace the sensor assembly.
Affected models
- Maytag MEDC465HW
- Maytag MEDB855DC
- Maytag MED6230HW
Prevention & maintenance
- Clean drain filters and hose terminations monthly on high-use dryers to prevent F07 from lint and food debris buildup.
- Record when F07 appears in the cycle and whether it clears after a 60-second power reset on your Maytag dryer—that detail speeds diagnosis if you call service.
- Keep the model and serial number from the rating plate when ordering parts for F07; Maytag uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting F07; reversed plugs on pumps and valves cause immediate repeat faults.
