Maytag Refrigerator Error Code 35
User interface board communication fault
What this error means
Code 35 means the dispenser or console UI lost communication with the main control. Temperature displays and ice/water requests may freeze.
How 35 is detected
When 35 appears on a Maytag refrigerator, the control board has confirmed that water did not leave the machine within the programmed drain window. On Maytag MFI2570FEZ, Maytag MSS25C4MGW, 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 35 calls are resolved without parts: unplug and remove the dispenser facade to reseat ribbons. 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 35 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
- Loose ribbon cable at the dispenser UI
- Condensation on connectors in the door after humid weather
- Power surge damaging the UI board
- Door harness wire broken at the hinge
Step-by-step fixes
- 1Unplug and remove the dispenser facade to reseat ribbons
- 2Dry any moisture on connectors with a cloth
- 3Inspect the hinge area for chafed wires
- 4Restore power and test display response
When to call a technician
Good harness continuity with dead display segments needs UI board W11174836 or equivalent.
Affected models
- Maytag MFI2570FEZ
- Maytag MSS25C4MGW
- Maytag MFF2055FRZ
Prevention & maintenance
- Clean drain filters and hose terminations monthly on high-use refrigerators to prevent 35 from lint and food debris buildup.
- Record when 35 appears in the cycle and whether it clears after a 60-second power reset on your Maytag refrigerator—that detail speeds diagnosis if you call service.
- Keep the model and serial number from the rating plate when ordering parts for 35; Maytag uses multiple revisions with different harness lengths and board firmware.
- Photograph wiring connector orientation before disconnecting any component while troubleshooting 35; reversed plugs on pumps and valves cause immediate repeat faults.
