KitchenAid Dishwasher Error Codes: What Every Code Means and What to Do Next

When your KitchenAid dishwasher flashes an error code, it is pointing to a specific system failure — not just telling you something is wrong. Understanding KitchenAid dishwasher error codes helps you decide whether a quick fix will resolve the problem or whether you need a certified technician. This guide covers the most common codes on KUDS and KDTM series models and gives you practical steps for each one.

KitchenAid dishwashers share a platform with Whirlpool, Maytag, and Jenn-Air models, so error codes follow consistent logic across all four brands. Once you understand the structure, even unfamiliar codes become easier to interpret.

How KitchenAid Dishwashers Display Error Codes

KitchenAid dishwashers communicate faults in two main ways, depending on the model year.

Flashing Light Sequences

Older models use LED lights that flash in patterns. One flash, a pause, then one flash indicates code 1-1. Count the first group of flashes, wait for the pause, then count the second group. That two-number combination maps to the codes listed below.

Alphanumeric Display Codes

Newer models with digital displays show codes directly — F1E1, F8E2, and so on. These remain on screen until you clear the error or cycle the power. If your model has a touchpad but no screen, consult the control panel reference card (often taped inside the door) to match indicator lights to specific codes.

How KitchenAid Dishwasher Error Codes Are Structured

Each code identifies two things: the affected system and the specific fault within that system. The first digit (or letter-number pair) names the system. The second names the fault.

  • Code 1-1 / F1E1: System 1 = Control board — Fault 1 = Relay stuck
  • Code 5-1 / F5E1: System 5 = Door latch — Fault 1 = Door switch error
  • Code 8-1 / F8E1: System 8 = Drain — Fault 1 = Slow or failed drain

This logic applies to every code in the table below. Knowing the system number alone often tells you where to start looking.

KitchenAid Dishwasher Error Code Reference

Code 1-1 / F1E1 — Stuck Control Relay

The relay on the main control board is stuck open or closed, preventing normal power delivery to components. The board itself is usually the cause.

What to try: Unplug the dishwasher for 30 seconds and restart. If the code returns immediately, the control board requires professional replacement — a reset will not fix a failed relay.

Code 2-1 / F2E1 — Stuck Touchpad Button

A button on the control panel is making continuous contact. This most often affects the Start, Cancel, or cycle-selection keys on the touchpad membrane.

What to try: Press the affected button firmly several times to free it. If it stays stuck, the touchpad membrane or full control panel assembly needs replacement.

Code 2-2 / F2E2 — Cancel/Drain Button Stuck

The Cancel or Drain button is registering as continuously pressed. The dishwasher treats this as an active command and aborts the cycle.

What to try: Check visually that no button is physically depressed. If the panel looks normal, the button contact or membrane has failed internally.

Code 3-1 / F3E1 — Water Temperature Sensor Fault

The thermistor — a small resistance-based temperature sensor — is reading out of range or has lost its connection to the control board. Without a reliable temperature reading, the dishwasher cannot complete a cycle safely.

What to try: Restart the cycle once. If the code returns, a loose wire harness or failed thermistor is the likely cause. This requires technician diagnosis.

Code 3-2 / F3E2 — Turbidity Sensor Failure

Found on newer KDTM-series models, the turbidity sensor measures water clarity and adjusts wash intensity accordingly. A fouled or failed sensor triggers this code.

What to try: Clean the wash chamber thoroughly and remove any standing debris from the sump area. If the code persists after cleaning, the sensor requires replacement.

Code 4-1 / F4E1 — Heating Element Not Reaching Temperature

The heating element is not reaching the set temperature, or its circuit has an open fault. Dishes may come out wet or cold.

What to try: Confirm your home water heater is set to at least 49°C (120°F). If it is, the element itself or its relay on the control board has failed and needs professional service.

Code 4-2 / F4E2 — Heating Element Relay Stuck

The relay controlling the heating element is stuck on the control board, preventing the element from cycling on and off correctly.

What to try: Restart the dishwasher after a 30-second power cut. If the code returns, the control board requires replacement.

Code 5-1 / F5E1 — Door Latch or Switch Error

The door latch is misaligned, cracked, or the magnetic switch is not detecting the closed-door position. The dishwasher will not start or will stop mid-cycle as a safety precaution.

What to try: Close the door firmly and listen for a solid click. Inspect the latch body for cracks or accumulated debris. If the door closes normally but the code remains, the door switch assembly needs replacement.

Code 5-2 / F5E2 — Door Left Open Too Long

The door has been open past the dishwasher’s programmed safety threshold. This protects against water overflow and steam escape.

What to try: Close the door completely and wait a few seconds — the cycle should resume on its own. If it does not, an underlying door switch fault may be present.

Code 6-1 / F6E1 — No Water Fill Detected

The dishwasher has not detected water entering the tub within the expected time window. Common causes include a closed supply valve, kinked inlet hose, or a failed water inlet valve solenoid.

What to try: Locate the hot water supply valve under the sink and make sure it is fully open — handle parallel to the pipe. Check the inlet hose for kinks. If water flows freely to the supply point, the inlet valve or solenoid has failed.

Code 6-2 / F6E2 — Water Inlet Valve Stuck Open

The inlet valve is not closing, and water continues filling the tub unchecked. Left unaddressed, this leads to overflow.

What to try: Turn off the water supply valve immediately. The inlet valve requires professional replacement — do not run the dishwasher again until the valve is replaced.

Code 7-1 / F7E1 — Booster Heater Fault

The booster heater — a secondary heating element that raises incoming water to wash temperature — is malfunctioning, or its control circuit is reading incorrectly.

What to try: Verify your home water heater is set to 49°C (120°F) or higher. If it is, the booster element or its wiring requires professional diagnosis.

Code 8-1 / F8E1 — Slow Drain

Water is draining slowly or the control board has timed out waiting for the tub to empty. The drain pump may be running but restricted, or the pump motor is weakening.

What to try: Remove the lower rack and clean the cylindrical drain filter — twist it counterclockwise, pull it out, and rinse it under hot water. Inspect the drain hose under the sink for kinks. If the tub still drains slowly after cleaning, the pump motor may be failing.

Code 8-2 / F8E2 — Drain Pump Not Responding

The drain pump motor is not activating or is not responding to signals from the control board. Water cannot exit the tub.

What to try: Confirm the drain filter is clear and the drain hose has no restrictions. If the pump still does not run, the motor or its wiring harness has failed and requires replacement.

Code 9-1 / F9E1 — Diverter Disk Error

The diverter disk — the wash arm selector that routes water between the lower and upper spray arms — is stuck or not rotating to the correct position. Wash coverage becomes uneven as a result.

What to try: Remove the lower spray arm and inspect the diverter disk at the base of the sump for debris, cracks, or calcium buildup. Clean and reinstall. If the disk remains stuck or is visibly cracked, the diverter assembly requires replacement.

DIY Troubleshooting Steps Before Calling for Service

Several error codes respond to basic maintenance. Work through these steps before scheduling a repair call.

Clean the Drain Filter

A clogged filter is the single most common trigger for F8E1. Remove the lower rack, locate the cylindrical filter at the base of the tub, twist counterclockwise, and pull it free. Rinse under hot water and scrub away food debris and mineral deposits with a soft brush. Reinsert and twist clockwise until snug.

Verify the Water Supply

F6E1 often traces back to a partially closed supply valve. Under the sink, find the hot water shutoff — a small brass valve with a lever or handle. Turn the handle so it sits parallel to the pipe. Also run your hand along the inlet hose to check for kinks or pinches.

Inspect the Door Latch

For F5E1 or F5E2, open the door and examine the latch assembly on the upper left edge of the tub opening. Clear out any crumbs, mineral scale, or debris caught in the latch mechanism. Close the door firmly and listen for a single clean click — that confirms the switch has engaged.

Power-Cycle the Dishwasher

Many transient errors clear after a proper reset. Unplug the unit at the wall (or switch off its dedicated circuit breaker) and wait 30 seconds. Restore power and start a new cycle. If the error was a one-time communication glitch, it should not return.

When a Technician Is the Right Call

If a code persists after these steps — or if it points to a component failure such as a heating element, drain pump, or control board relay — professional repair is the right move. Replacing internal components without the correct tools or wiring diagrams risks further damage and may void any remaining manufacturer coverage.

KitchenAid Dishwasher Error Codes: Frequently Asked Questions

Can I clear a KitchenAid dishwasher error code myself?

Yes — for transient codes caused by a power surge or brief sensor glitch, a 30-second power reset often clears the display. Unplug the dishwasher or switch off its circuit breaker, wait 30 seconds, then restore power and start a new cycle. If the same code reappears, the underlying fault has not been resolved and the component needs inspection or replacement.

What does the F8E1 code mean on a KitchenAid dishwasher, and is it serious?

F8E1 indicates a slow or failed drain. In many cases it is caused by a blocked drain filter or a kinked drain hose — both straightforward to fix yourself. If cleaning the filter and checking the hose does not resolve it, the drain pump motor may be failing. Left unaddressed, a failing pump will eventually prevent the dishwasher from completing any cycle.

Why does my KitchenAid dishwasher show a door error even though the door is closed?

Error code F5E1 can appear even when the door looks fully shut. The magnetic door switch — a small component inside the latch assembly — may be misaligned or worn. Debris caught in the latch can also prevent the switch from seating correctly. If cleaning the latch area does not resolve the code, the switch itself needs replacement.
