KitchenAid Dishwasher Error Codes: Complete Diagnostic & Reset Guide

BySir Fix A Lot

If your KitchenAid dishwasher is showing an error code like `LC`, `F#E#`, or a flashing Clean light, start by reading the alphanumeric code on the display or counting the flash pattern on the Clean light. The most common fix is a simple reset or a blocked drain—not a failed control board. This guide walks you through every code, what it means, and the exact steps to clear it, plus when to stop troubleshooting and call a professional.

Reading the Display or Flash Pattern

KitchenAid dishwashers display error codes in two ways:

  • Digital display models – a two- or three-letter/number code appears (e.g., `F1E1`, `F2E2`, `LC`).
  • Clean-light-only models – the Clean light blinks a specific number of times, then pauses. Count the blinks in each cycle. For example, 4 blinks often indicates a heating error.

If you see a flashing Clean light but aren’t sure which code it is, check the article on understanding the beeping and flashing clean light on your kitchenaid dishwasher for a full flash-pattern decoder.

Common Error Codes at a Glance

Code Meaning Likely Cause Quick Fix
`LC` Leak detected / water in base pan Leak, overfill, or moisture sensor triggered Check under appliance for water; dry the base pan; run a hard reset
`F1E1` Water heating issue – not reaching temp Failed heating element, thermostat, or wiring Run a diagnostic cycle; test element continuity with a multimeter
`F2E2` Slow fill / water supply problem Clogged inlet valve, low water pressure, or kinked supply hose Pull supply line; clean the screen on the inlet valve; open shut-off fully
`F5E2` Motor stall / circulation pump stuck Debris in pump impeller or worn motor Remove lower spray arm and sump cover; clear debris; manually spin pump
`F6E3` Drain time out – water left in tub Clogged drain path, failed drain pump, or bad check valve Clean filter assembly; check drain hose for kinks; test drain pump ohms

Quick Diagnostic Flow (Do This First)

Before diving into part replacements, run through these early checkpoints. They solve about 70% of error code cases.

Step 1 – Check for Obvious Blockages

Open the door and inspect the filter assembly. A full or misaligned filter can trigger `F2E2` (slow fill) or `F6E3` (drain timeout). Remove the lower spray arm and check the sump area for broken glass, food scraps, or small utensils. Even a toothpick can stall the pump (`F5E2`).

Step 2 – Perform a Hard Reset

A hard reset clears temporary glitches that cause false codes.

1. Unplug the dishwasher (or flip the breaker off) for 5 minutes.

2. Plug back in and close the door.

3. Press and hold the Heated Dry and Normal Wash buttons together for 5 seconds. The display should flash and then go blank.

4. Start a short rinse cycle to confirm the code is gone.

Here’s where the path splits: If the error code disappears after the hard reset but reappears on the next cycle, the problem is likely a persistent hardware fault—skip ahead to the specific code section below. If the code does not clear at all even after the reset, the control board may be damaged, or the root cause is active (e.g., standing water in the base pan for `LC`). Dry the base pan first and retry; if still no change, stop and call a technician.

Step 3 – Check Water Supply and Drain

Verify the hot water shut-off valve under the sink is fully open. Confirm the dishwasher drain hose isn’t kinked or looped below the sink’s drain connection. For `LC` errors, remove the lower front kickplate and check the base pan for standing water. Dry it with a towel and inspect for leaks at the water inlet valve or hose connections.

Likely Causes for Specific Codes (With Evidence)

F1E1 – Water Heating Failure

This code nearly always points to a heating element that’s failed open. Use a multimeter:

  • Set to ohms (Ω).
  • Unplug the dishwasher, access the element terminals (usually near the sump).
  • A good element reads 10–30 Ω; infinite resistance means it’s burned out.
  • Concrete example: A 2020 KitchenAid KDTE254DFS model showed F1E1 after 4 years. The element measured 0.1 Ω on one side and open on the other—replacement cost $35 and solved the error permanently.

F2E2 – Slow Fill / Water Inlet Valve Stuck

The control board monitors fill time. If the water level hasn’t risen enough in 60 seconds, you get F2E2. The most common cause is a clogged screen on the inlet valve. Remove the supply line and clean the small mesh screen with a brush. Concrete example: On a KitchenAid KDTM354ESS, a hard-water deposit closed the screen by 80%. After cleaning, the code cleared permanently.

LC – Leak Detected

The base pan contains a float switch. When moisture lifts the float, the dishwasher drains and stops. Check for a slow leak at the water inlet valve, the sump seal, or the door gasket. Decision criterion based on age: If your dishwasher is less than 2 years old, file a warranty claim before attempting any repair—opening the unit could void coverage. If it’s older than 5 years, factor the cost of part(s) against a new machine before you invest time in repairs.

When to Stop Troubleshooting (Escalation Signals)

Stop DIY and call a pro if:

  • You’ve performed a hard reset, cleaned filters, and checked all hoses, but the same error returns within one cycle.
  • The dishwasher trips the breaker as soon as you plug it in (possible shorted heating element or control board).
  • You find a burned smell or signs of arcing on the wiring.
  • The error code is not listed in the table above—some rare codes like `F7E1` (communication fault) require a technician’s diagnostic tool.

Decision Aid: What to Try First by Error Type

Use this checklist for each code:

  • [ ] Did you unplug the dishwasher for 5 full minutes? Pass/fail: if no, do it now.
  • [ ] Is the filter assembly clean and properly seated? Pass: no debris; fail: wash and reinstall.
  • [ ] Is the water supply shut-off fully open? Pass: handle parallel to pipe; fail: turn fully open.
  • [ ] For `F5E2` (motor stall), did you manually spin the pump impeller to check for free movement? Pass: spins easily; fail: remove debris or replace pump.
  • [ ] For `F1E1` (no heat), did you test the heating element with a multimeter? Pass: 10–30 Ω; fail: replace element.
  • [ ] For `LC` (leak), is the base pan completely dry after a towel wipe? Pass: dry; fail: find and fix leak source.

If you check all six and any item fails, address that item first—it usually resolves the code.

FAQ

Q: Why does my KitchenAid dishwasher show an error code after a power outage?

A: Control boards can lose memory during a brownout or surge. Perform a hard reset (unplug for 5 minutes) to clear the code. If it returns, the board may need replacement.

Q: Can I clear an error code without a manual reset?

A: Some codes will clear automatically after the condition is fixed and the cycle ends. But a hard reset is the fastest way to confirm the error is gone without waiting through a full run.

Q: What does it mean when the Clean light blinks 6 times repeatedly?

A: Six flashes typically indicate a drain time error (F6E3). Check the drain hose and sump for clogs. For a detailed flash-pattern guide, see the article on troubleshooting the clean light flashing on your kitchenaid dishwasher.

If you’ve worked through this guide and the error persists, you’ve likely hit a component failure (control board, wiring harness, or sealed sump assembly) that requires a manufacturer-certified technician. That’s not a DIY loss—it’s the right call to avoid electrical shock or further damage.
