Maytag Dishwasher Error Code F6E2 — What It Means & How to Fix It

What Does This Error Mean?

F6E2 means the user interface board (behind the control panel) has lost communication with the main control board — the same type of fault as F6E1 but detected from the UI board side. The two boards must exchange data continuously throughout a cycle. A power reset clears it in many cases; a persistent F6E2 usually points to a wiring harness fault or a failed UI board.

Affected Models

Maytag MDB7959SHZ
Maytag MDB4949SHZ
Maytag MDB8959SFZ
Maytag MDB Series

Common Causes

Communication signal between the user interface board and main control board has failed
Wiring harness connector at the user interface board end is loose or unseated
User interface board has an internal failure preventing it from communicating
Power surge has damaged the user interface board
Wiring harness has a broken wire between the two boards

How to Fix It

Turn off the dishwasher at the circuit breaker for 5 full minutes, then restore power and run a test cycle.

F6E2 is frequently caused by a transient communication dropout — a power reset clears it in many cases.
If F6E2 returns immediately, check the wiring harness connector at the user interface board — typically behind the control panel door liner.

The UI board connector is one of the most common failure points for F6E2. A connector that was not fully clicked home, or has worked loose, can cause a persistent communication fault.
Disconnect the harness connector at the UI board, inspect the pins for corrosion or damage, and reconnect firmly until it clicks.

Do not do this with the dishwasher powered on. Turn off the breaker before opening the door panel.
If the harness is intact but F6E2 persists, have a technician test the UI board and main control board.

Board replacements are expensive — a technician can confirm which board is at fault before ordering parts.

When to Call a Professional

A persistent F6E2 that returns after a power reset and harness check indicates a failed user interface board or, less commonly, the main control board. A technician can confirm which board has failed before any parts are ordered.

Frequently Asked Questions

What is the difference between F6E1 and F6E2?

Both indicate a communication failure between the main control board and the user interface board. F6E1 is detected at the main control board end; F6E2 is detected at the user interface board end. The causes and fix steps are nearly identical — a power reset and harness check are the first steps for both.

Can a power outage cause F6E2?

Yes. A sudden power cut during a wash cycle can cause the two boards to lose sync, triggering F6E2 on the next startup. A circuit breaker power reset almost always clears this type of fault.

How much does a user interface board replacement cost?

A replacement user interface board for a Maytag dishwasher typically costs $50 to $130 for the part. With technician labor, the total repair usually runs $150 to $280.
