KitchenAid Dryer Error Codes — Full Diagnostic Reference

Common Symptoms

• Error code displayed on KitchenAid dryer panel (F1E1, F2E1, F3E1, F3E2, F4E1, F4E3, F5E1, F6E1, F7E1, E1)
• Dryer stops mid-cycle with a fault code on the display
• Dryer runs but produces no heat — F3E1, F3E2, or F4E3
• Steam dryer shows E1 — steam cycle not producing steam or shutting down
• Dryer will not start — F5E1 door switch or F7E1 motor fault on KHED01
• Control panel unresponsive or communication error — F2E1 or F6E1

Most Likely Causes

1. 1

   F1E1 — Main Control Board EEPROM Fault

   F1E1 on KitchenAid dryers indicates the main control board's internal EEPROM memory has detected an error or corruption. Identical in cause and resolution to Maytag and Whirlpool F1E1. First step: unplug the dryer for 5 minutes and restore power — transient voltage events can trigger F1E1 on an otherwise-functional board. If F1E1 persists after a full power cycle, the control board must be replaced. Inspect the board for burned components or domed capacitors. The control board is accessible from the rear top panel on YKHEC and YKHEV models.

2. 2

   F2E1 — Keypad Fault (Stuck Key)

   F2E1 indicates one or more control panel keys are registering as continuously pressed or the keypad is not communicating with the main board. Causes include moisture ingress, debris under the keypad membrane, or a loose ribbon cable. Diagnosis: unplug, disconnect the keypad ribbon at the main board, reconnect power — if F2E1 clears, the keypad has failed. Try cleaning under the membrane with isopropyl alcohol. If cleaning does not resolve it, replace the keypad assembly (check model-specific part for YKHEC3014VW vs YKHEV1014HV).

3. 3

   F3E1 — Exhaust Thermistor Fault (WPW10661028)

   F3E1 indicates the exhaust thermistor WPW10661028 is out of range or has failed. Shared part with Maytag and Whirlpool platform dryers. At room temperature (~70°F), a functional WPW10661028 reads approximately 10,000Ω (10kΩ). OL = open (failed), near-0Ω = short (failed). The thermistor is mounted on the exhaust duct inside the cabinet — accessible via rear panel removal on YKHEC3014VW and YKHEV1014HV. F3E1 is the most commonly replaced KitchenAid dryer sensor. Test procedure: unplug, disconnect two-wire connector, probe with multimeter in resistance mode.

4. 4

   F3E2 — Inlet Thermistor Fault

   F3E2 indicates the inlet thermistor (monitoring air temperature entering the drum from the heater) is out of range or has failed. Less common than F3E1 on KitchenAid models. Same test procedure as F3E1: resistance should be approximately 10kΩ at room temperature. On YKHEV1014HV (steam models), the inlet thermistor may be positioned differently than on standard YKHEC models — access typically requires front panel removal.

5. 5

   F4E1 — Heater Relay Stuck On (Safety-Critical)

   F4E1 indicates the heater relay on the main control board has welded in the closed position — the heating element is energized when the board is commanding it off. This is the same safety-critical fault as Maytag F4E1 and Whirlpool's equivalent heater relay fault. The dryer shuts down to prevent overheating. Do not restart the dryer until the control board is replaced. The heating element WPW10082415 (KitchenAid branded, electrically identical to Maytag WP8544771) is not the cause of F4E1 — the relay is on the board, not the element.

6. 6

   F4E3 — Heater Relay Open (No Heat)

   F4E3 indicates the heater relay is open when heat is commanded — the dryer runs but produces no heat. Diagnosis sequence: test the high-limit thermostat (WP8577274 — continuity at room temp), thermal fuse (if present in series with heater), and heating element WPW10082415 (should read approximately 10Ω). If these all test functional, the heater relay on the control board has failed open and the board must be replaced. On YKHEV1014HV steam models, the steam inlet valve circuit runs separately from the main heater relay — F4E3 should not cause steam function loss.

7. 7

   F5E1 — Door Switch Open Mid-Cycle

   F5E1 indicates the door switch WPW10619763 opened during a running cycle, or the door is not confirmed closed at cycle start. Shared part with Maytag and Whirlpool platform. Test: unplug, access door switch, probe in continuity mode — plunger pressed = continuity, plunger released = open. A switch that reads open with plunger pressed is failed. Inspect the door latch strike (plastic tab on the door) for cracks or missing material. On YKHEC3014VW, the door latch tab is prone to wear with repeated heavy door closing.

8. 8

   F6E1 — UI Board to Main Board Communication Fault

   F6E1 indicates the user interface board and main board have lost communication. Same as Maytag F6E1. Always reseat the ribbon cable first — this resolves F6E1 in many cases without board replacement. Unplug the dryer, access the control console (typically 2–4 screws at the rear top on YKHEC/YKHEV models), and firmly reseat the ribbon cable at both ends. On YKHEC3014VS and YKHEC3014VW, the ribbon cable routes across the console hinge point and can develop micro-fractures from lid opening and closing — inspect for kinking.

9. 9

   F7E1 — Motor Speed Sensor Fault (KHED01 Models)

   F7E1 is a KitchenAid-specific code found primarily on the KHED01PWH0 and related models that use a motor speed sensor (tachometer) in the motor control circuit. The sensor monitors drum rotation speed; if the board does not detect normal motor speed within a set window, F7E1 is generated. Causes: failed motor speed sensor, loose harness connection to the sensor, or a motor with degraded bearings causing inconsistent speed. Diagnosis: check the motor speed sensor wiring harness for loose connections first. If harness is intact, test the sensor resistance per the KHED01 service manual. Motor replacement (WPW10448896) is only warranted after confirming no relay, thermistor, or sensor harness fault.

10. 10

    E1 — Steam Function Fault (YKHEV Steam Models)

    E1 on KitchenAid steam dryers indicates a fault in the steam generation circuit — either the water inlet valve WPW10605427 is not opening or has failed, or the steam generator W10598983 has accumulated mineral scale deposits that are preventing steam production or causing the steam function to shut down on overheat. E1 does not affect the standard drying function — only the steam cycle is impaired. Diagnosis: (1) verify the water supply valve behind the dryer is open and water pressure is adequate (minimum 20 PSI); (2) test water inlet valve WPW10605427 solenoid resistance (approximately 200–500Ω); (3) inspect the steam generator W10598983 for scale buildup — white mineral deposits visible inside the generator tube indicate descaling is needed. Descale with white vinegar per the owner's manual before replacing components.

Quick DIY Checks

1. 1Enter KitchenAid dryer service mode: on most YKHEC and YKHEV models, press and hold Wrinkle Shield and Start simultaneously for 3 seconds. The display will enter service mode and show stored fault codes. On KHED01PWH0, use the Power + Start button sequence instead — hold Power, then press Start within 3 seconds. If service mode is not accessible on your model, note the error code displayed at the time of the fault. Some YKHEC3014VS models may use a different key combination — consult the service manual if neither method works.
2. 2Test exhaust thermistor WPW10661028 (F3E1): unplug the dryer. Remove the rear panel (6–8 Phillips screws on YKHEC3014VW and YKHEV1014HV). Locate the thermistor on the exhaust duct — two-wire cylindrical or flat sensor. Disconnect the connector. Set multimeter to resistance (Ω) mode. Probe both thermistor terminals. At room temperature: approximately 10,000Ω = functional. OL = open (replace). Near 0Ω = short (replace). WPW10661028 is a shared part across KitchenAid, Maytag, and Whirlpool platform dryers.
3. 3Test heating element WPW10082415 (F4E3 / no heat — electric models): unplug the dryer. Remove the rear panel to access the heater box. Set multimeter to resistance mode. A functional WPW10082415 reads approximately 10Ω (electrically identical to Maytag WP8544771 — same coil, KitchenAid-branded part number). OL = open coil (failed, replace element). Check for continuity between any element terminal and the heater box frame — any reading indicates a ground fault; replace the element. Also test the high-limit thermostat on the heater box: continuity at room temp = functional.

1. 4Test door latch WPW10619763 (F5E1): unplug the dryer. Access the door switch from the front (front panel removal typically required on YKHEC/YKHEV models — remove the toe panel screws and lift off the door strike area). Disconnect switch wires. Set multimeter to continuity mode. Plunger depressed (door-closed simulation): continuity. Plunger released: open. A switch that reads open with the plunger pressed is failed. Inspect the plastic latch tab on the door for cracks or worn tip. Shared part WPW10619763 with Maytag and Whirlpool platform.
2. 5Reseat ribbon cable for F6E1 communication fault: unplug the dryer. Remove 2–4 screws at the rear top of the console to access the control board area. Locate the ribbon cable connecting the UI board to the main board. Firmly pull the ribbon connector straight out, then reinsert until fully seated. Check both ends of the ribbon cable for pinching or visible flex cracks, especially on YKHEC3014VS where the cable routes over the console hinge. Reassemble and run a cycle. If F6E1 returns after reseating, the ribbon cable has a micro-fracture or a board has failed.
3. 6Diagnose E1 steam fault on YKHEV models — water inlet and steam generator inspection: shut off the water supply valve behind the dryer before working on the water circuit. Check that the water supply line is connected and the valve is open. With the valve shut, disconnect the inlet water line from the back of the dryer (have a towel ready). Reconnect power and run a steam cycle — if the dryer shows E1 immediately without even calling for water, the inlet valve WPW10605427 solenoid may have failed. Unplug, access the inlet valve (rear panel removal), and test solenoid resistance: approximately 200–500Ω = functional. OL = failed solenoid, replace inlet valve. If the inlet valve tests functional, remove the steam generator access panel (typically lower front) and inspect the steam generator W10598983 tube for white scale deposits — descale with diluted white vinegar before replacing.
4. 7Test motor speed sensor and motor for F7E1 (KHED01 models): unplug the dryer. Access the motor and motor speed sensor (bottom front access on KHED01PWH0 — remove the toe panel and lower front panel). Locate the motor speed sensor harness connector on the motor body. Inspect the connector for loose, corroded, or bent pins — disconnect and reseat firmly. If F7E1 persists after connector reseat, test the motor speed sensor resistance per the KHED01 service manual specification (varies by sensor model). If the sensor tests out of spec, replace the sensor. Only proceed to motor replacement (WPW10448896) after confirming the sensor, its connector, and the harness wiring are all functional.
