Whirlpool Washer F3E2: Inlet Thermistor Circuit Checks

On the W11349355A configuration, F3E2 means an inlet-water-temperature fault. The control detects an open or shorted inlet thermistor circuit. The thermistor, wiring, and control must be considered together.

Applies to: the Whirlpool top-load washer configuration documented in service sheet W11349355A. It does not supply universal instructions for all Whirlpool, Maytag, Amana, Kenmore, Cabrio, Bravos, or front-load washers. Check the full model number and its technical sheet first.

⚠️ SAFETY FIRST: Always unplug the appliance you're working on from the wall outlet, turn off the breaker, or both, to completely disable power before opening the top console or touching electrical wiring.

Make the situation safe

Disconnect power before opening panels, disconnecting connectors, or checking resistance or continuity. Never bypass the lid interlock or reach into a moving basket. Live electrical measurements belong to a qualified appliance-service professional following the complete OEM procedure. Drain the tub using the model’s approved method before underside access, and support the machine securely. Do not work beneath an unsupported tilted washer.

Check the actual temperature and supply arrangement

Record the cycle and whether incoming water appears inconsistent with the selected temperature. Verify hose connections against the installation instructions. Do not reach into hot water to estimate its temperature. The fault does not establish that every washer uses the same sensor or replacement assembly.

Technician diagnosis: TEST #5: temperature thermistor

The following checks require the matching OEM sheet and safe access. Isolate power before connecting or disconnecting test leads or harnesses; resistance tests use the disconnected harness or isolated component specified by the OEM. Follow all live-measurement precautions in the sheet.

The OEM test begins by confirming cold and hot valve operation and correct hose connections. With power disconnected, remove J9 from the main control and measure the thermistor path across J9-3 and J9-7. Compare with the approximate temperature-dependent readings in the sheet. A control-end reading includes wiring and connections.

TemperatureApproximate resistance, W11349355A
0°C / 32°F163 kΩ
20°C / 68°F62 kΩ
25°C / 77°F50 kΩ
40°C / 104°F27 kΩ

The complete curve appears on page 17. These are approximate values for the documented thermistor, not a universal ±10% rejection rule. Evaluate an open, short, or unexpected reading under the complete procedure and inspect the harness before replacing parts. The source notes fallback wash settings when the thermistor malfunctions; do not assume every F3E2 aborts every model’s cycle.

Retrieve the stored fault before replacing parts

On the matching W11349355A configuration, use the following sequence with the washer fully assembled. Stop if there is uncontrolled filling, leakage near electrical equipment, severe mechanical movement, or a burning smell.

  1. Place the washer in standby: plugged in, with all indicators off. After initial power is applied, wait 10 seconds.
  2. Turn the cycle selector counterclockwise one or more clicks to reset the entry sequence. This does not erase stored faults.
  3. Within six seconds, turn clockwise one click three times, then counterclockwise one click, then clockwise one click. Allow about half a second between movements.
  4. Successful entry makes the status LEDs flash together, except Lid Locked. Turn the selector until only Done is illuminated, then press Start.
  5. Turn clockwise to review the four most recent stored faults. Record them before clearing anything.

If pump-out is active, diagnostics are unavailable until it completes. OEM W11349355A describes holding Start for three seconds to cancel pump-out before retrieving faults. Removing power pauses pump-out; it does not reset that condition. Use this step only when the washer can be operated safely.

Select parts only after confirmation

Use the complete model number, engineering revision, and confirmed failed component to select a replacement. A code alone does not prove that the named component is defective. Generic product photographs and a similar-looking part do not establish fitment.

Verify the repair

Reassemble all panels and reconnect every disturbed connection before normal operation. Correct any leak or mechanical hazard before running a test. On this documented configuration, select Automatic Test Mode from diagnostics with the Spin LED, then press Start; the lid must be closed and locked. The programmed test uses water. A pass illuminates the status LEDs for five seconds; a failure flashes them for five seconds. Retrieve any faults after a failed test and continue diagnosis.

Calibration and fault-history clearing are different operations. W11349355A limits Calibration Mode to models without level selection, and lists replacement of the main control, basket, drive assembly, suspension, motor, and capacitor as calibration triggers. Follow the relevant component-test procedure as well. Where required, use an empty basket, lid down, select Rinse in diagnostics, and press Start. Allow approximately two to four minutes without interruption; some configurations take longer.

To clear history after recording it, enter Fault Code Display Mode, turn to the flashing-status-LED position, and hold Start for three seconds. The sheet also removes a fault after five consecutive wash cycles without recurrence. Clearing history is not a repair or a calibration step.

OEM reference and applicability

Technical basis: Whirlpool W11349355A, F3E2 fault chart page 6; TEST #5 pages 16–17; diagnostic and verification modes pages 2–4. AFC’s library associates this sheet with WTW4816FW3 and WTW4850HW3. Match the technical sheet supplied with the complete model number and revision before using these procedures. A similar control panel does not establish applicability. The OEM sheet is intended for service technicians.
