Test mode on the display
Three codes, t1, T2 and tSt, tell you the washer is in test mode. Older units can show ee2, t2 or tSt instead. All of this comes from Samsung’s Levant article, which sets current and legacy codes side by side, so model differences are possible and the manual should stay close.
Leaving test mode
Disconnect the washer at the mains.
Count out 30 seconds.
Reconnect, then pick a new programme.
The code is still there? Contact customer support.
Samsung washer service on the San Francisco peninsula
A Samsung washer in San Francisco that remains in test mode after the reset can be taken up through Samsung washer repair or at (415) 969-6153. Say which of the codes is showing and read out the model number.
Model compatibility: Samsung reuses codes across series and model years, so t1, T2, tSt may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
