Answer to continue safely
Is it safe to keep using?
No. With communication between boards interrupted, the dryer cannot be safely controlled. Do not operate until the fault is resolved.
Can I reset the code?
Yes. A 60-second hard reset may clear a temporary communication error. Persistent faults require cable or board repair.
When to stop immediately?
Stop if you notice: Stop if the dryer starts and stops erratically without user input — unpredictable operation is a safety concern., Stop if the error appears every cycle regardless of load size, indicating a hardware failure rather than an intermittent connection..
Symptoms You May Notice
Dryer stops mid-cycle and the display freezes or goes blank
The communication loss causes the UI to either freeze on the last displayed cycle time or go completely dark while the machine halts.
Control panel buttons become unresponsive during a cycle
As the communication link degrades, button presses are not transmitted to the main board, making the dryer appear locked up.
Dryer repeatedly starts and stops on its own
An intermittent connection causes the communication link to drop and re-establish, cycling the dryer on and off erratically.
Error appears more frequently when the dryer vibrates heavily
A marginally seated ribbon cable loses contact during vibration, triggering F6E2 with larger or unbalanced loads.
Possible Causes
Loose or damaged ribbon cable
The data cable between the main board and UI board has worked loose or developed a crack, breaking the communication path.
DIY PossibleFailed main control board communication circuit
The serial communication IC on the main board has failed, preventing it from transmitting data.
Requires ProfessionalFailed UI board communication circuit
The UI board's receiver circuit has failed and can no longer acknowledge signals from the main board.
Requires ProfessionalSafe Checks You Can Do
-
1
Hard reset the dryer
Unplug for 60 seconds. Restore power and attempt a fresh cycle. A transient communication glitch from a voltage spike will often clear this way.
If the code returns only with heavy or unbalanced loads, focus on the ribbon cable connection before replacing any boards.

2
Reseat the ribbon cable on both ends
Unplug the dryer and remove the control panel cover. Locate the ribbon cable connecting the UI board to the main board. Press both connectors firmly until fully seated. Inspect for visible cracks along the cable length.
Ribbon cable connectors have a small locking tab — flip it up to release, insert the ribbon fully, then close the tab.
Tools required -
3
Inspect for chafed or pinched harness wires
If the two boards are connected by a wire harness rather than a ribbon cable on your model, trace the harness for any sections pinched by a panel edge or bracket.
Use a flashlight to inspect hard-to-see harness runs at the back of the control console.
When to Call a Professional
Contact a qualified technician if:
- The ribbon cable is fully seated and undamaged but the error persists, indicating a board-level communication failure.
- The error began immediately after a power outage or surge, suggesting the communication IC on one of the boards was damaged.
