Model: GFW550SSN2WW Main Symptom: Powers up, cycle is selected, Start is pressed, nothing happens, then the washer eventually shuts itself off. UI has already been replaced.
Most likely causes (in order)
Main Control Board (Most Likely)
Since the new UI did not change the symptom, the main control is the next most likely failure.
This model is known for main board failures that cause the washer to accept selections but never initiate a cycle before powering down. Multiple field reports describe this exact symptom being resolved by replacing the main control.
Door Lock Assembly
If the control never sees the door lock engage, it will refuse to start the cycle.
Listen for the lock clicking when Start is pressed. If there is no lock attempt, verify the door lock and harness before condemning the board.
Harness / Communication Issue
Check the UI-to-main-board harness and the door lock connector for backed-out pins or corrosion.
Verify all connectors are fully seated after replacing the interface.
Before replacing the control board
Perform a 2-minute power reset by unplugging the washer or switching off the breaker, then retry.
Enter service diagnostics if possible.
Check for stored error codes.
Run the door lock test.
Verify the main board has proper line voltage (120 VAC) and that its low-voltage supply to the UI is present.
My recommendation
Based on your description:
UI replaced with no change
Unit accepts selections but never begins the cycle
Eventually powers itself off
I would suspect the main control board next, provided:
the door lock is functioning,
wiring checks good,
and diagnostics don’t point to another component.
If you can retrieve the stored error codes or tell me:
Door lock does not click nor does it show on the interface as locked. After it refuses to cycle interface goes dark and i can hear a slight “Click/Click” sound every few seconds.
For GE GFW550SSN2WW, based on your symptoms, I would not condemn the UI (you already replaced it), and I would not immediately condemn the main control board until a few checks are made.
Symptoms
Select a cycle → press Start → nothing happens.
Door never locks (no audible lock engagement).
Lock indicator never appears on the display.
Eventually the UI goes dark.
A faint click is heard every few seconds.
Main control board has two LEDs flashing.
Most likely causes (in order)
Door Lock Assembly (Most Likely)
Since the lock never attempts to engage and the control never sees a locked door, the washer will not start.
A failed lock or an open harness can also cause repeated relay clicking while the board repeatedly tries to start.
Door Lock Wiring
Check the connector at the lock.
Inspect the harness from the lock back to the main board for broken wires, especially where the harness flexes.
Main Control Board
Possible, but only after verifying:
Proper line voltage into the board.
The board is actually supplying voltage to the door lock when Start is pressed.
Harness is good.
About the two flashing LEDs
On this GE platform, two flashing LEDs on the inverter/main control generally indicate the board has power and is operating, not necessarily that it has failed. The blink pattern by itself isn’t enough to diagnose a bad board. The service sheet specifies what the pattern means.
What I’d test next
Enter Service Mode if possible.
Run the Door Lock test.
If the lock never actuates, continue with electrical checks.
Measure voltage at the door lock while pressing Start.
If the board sends the proper voltage but the lock never engages → replace the door lock assembly.
If no voltage is sent, verify harness continuity.
Ohm-check the door lock harness from the control to the lock.
If:
harness is good,
lock tests good,
board never outputs lock voltage,
then the main control board is the likely failure.
For the GE GFW550SSN2WW front-load washer, the Field Service (Diagnostic) Mode entry is:
Make sure the washer is powered on but idle (no cycle running).
Press and hold the START/PAUSE button.
While continuing to hold START, rotate the cycle selector knob clockwise at least 180° (about 6 clicks).
Release START.
The display will enter Field Service Mode and show Test 0. Rotate the cycle knob to select test numbers, then press START to run the selected test.
Once you’re in Field Service Mode (display shows Test 0), use the cycle selector knob to scroll through the tests. Press START to enter the selected test.
Read stored fault codes
Select Test 1 – Fault Codes
Press START.
Rotate the cycle knob to scroll through stored codes (if more than one is present).
If no faults are stored, the display will indicate none are present.

Clear fault codes
Select Clear Fault Codes (typically Test 16).
Press and hold START until the display confirms the memory has been cleared.
Exit diagnostics
Press POWER, or unplug the washer for a few seconds.
If you tell me the fault codes you read (for example 3, 26, 38, 39, 50, 92), I can interpret each one and walk you through the next diagnostic steps.
Yes the stuck lock piece may be part of the issue but the code 92 is also an issue
or a GE GFW550SSN2WW, Fault Code 92 indicates an inverter fault. The inverter board controls the washer’s drive motor.
Common causes:
Failed inverter board (most common)
Loose or damaged wiring between the main control, inverter, and motor
Defective drive motor (less common)
Failed main control board (can also trigger or accompany Code 92)
To narrow it down:
Unplug the washer for 5 minutes and reconnect.
Enter service mode and run Spin Test 14. If it completes successfully, the fault may have been temporary. If it fails or Code 92 returns, continue troubleshooting.
Inspect the wiring harnesses at the inverter, motor, and main board for loose or burned connections.
If wiring is good, the inverter board is the first part typically replaced. If replacing the inverter does not resolve the issue, the main control board is the next most common culprit.
Can you tell me:
Does the washer power on normally?
What happens when you press Start? (Nothing, clicks, drains, locks the door, etc.)
Are there any other fault codes stored besides 92?
Washer powers on normally, board lights up normally and i can scroll through all the options. However nothing happens when i press start other than a click every few seconds. Like its trying to work. then it shuts off. The door does not lock nor do i hear it attempting to. No other fault codes that i can find.
UI replaced with no change
