Answer to continue safely
Is it safe to keep using?
Maybe. EH0 is a communication fault, not a heating or electrical safety issue. The dryer is unlikely to pose a fire risk, but it will not operate correctly. If the error is intermittent and the dryer occasionally runs, it is not dangerous, but repair should be scheduled promptly.
Can I reset the code?
Yes. A power cycle often temporarily clears EH0. If the cause is a loose connector that you reseat, the fix may be permanent. If a board has failed, the code will return.
When to stop immediately?
Stop if you notice: Stop if you cannot identify the wiring connectors between the boards; disassembling beyond the top panel may void warranty., Do not attempt to repair or solder components on either circuit board without proper training and equipment..
Symptoms You May Notice
Dryer completely unresponsive
Pressing any button on the control panel produces no response, and the dryer will not start any cycle.
EH0 flashes on display
The display shows EH0 either continuously or intermittently, sometimes appearing briefly before the display goes blank.
Display shows partial information
The control panel display may light up partially but show garbled or incomplete cycle information.
Dryer stops mid-cycle randomly
The dryer may start a cycle but then stop unexpectedly as the communication link drops out intermittently.
Possible Causes
Loose wiring harness connector
The multi-pin connector linking the UI board and main control board has vibrated loose, interrupting the serial data communication.
DIY PossibleFailed user interface board
The UI board behind the control panel has malfunctioned and stopped transmitting data to the main control board.
Requires ProfessionalDamaged communication wiring
The wire harness between the boards has been pinched, chafed, or had a wire break internally, breaking the data link.
Requires ProfessionalSafe Checks You Can Do
-
1
Power reset the dryer
Unplug the dryer for at least 5 minutes, then plug it back in. Check whether the display initializes normally and the code clears.
Communication faults can sometimes be caused by momentary electrical interference and resolve with a simple reset.

2
Reseat board connectors
Unplug the dryer. Remove the top panel or control console screws to access the wiring between the boards. Disconnect and firmly reseat each connector.
Take a photo of each connector before removing it so you can verify correct orientation when reconnecting.
Tools required -
3
Inspect harness for damage
Follow the wiring harness between the two boards, checking for any pinched, chafed, or broken wires along the entire route.
Pay close attention to areas where the harness passes through metal brackets or bends sharply, as these are common damage points.
When to Call a Professional
Contact a qualified technician if:
- The UI board display partially powers on but fails to communicate cycle selections to the main board.
- Reseating all connectors does not resolve the EH0 code, indicating a board-level component failure.
- The main board enters diagnostic mode successfully from its own test points but cannot communicate with the UI board.
