Quick answer
This code group is a voltage error: the electrical supply to the washer is irregular. PF means power was lost.
Model compatibility: Samsung reuses codes across series and model years, so 9C1 / 9C2 / PF / 3E / 2E / 9E1 / 9E2 / UC / 19C1 / 19C2 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Voltage error: irregular electrical supply. PF means power was lost before the washer shut off. On some models 3E is a motor error.
9C1, 9C2, PF, 3E, 2E, 9E1, 9E2, UC, 19C1 and 19C2 are listed by Samsung as a voltage error, which means the electrical current supplied to the washer is irregular. Samsung lists it for all generations. Washers used outside their country of origin can show it too, because power grids and their regulations vary between countries.
PF in particular
A PF (Power Failure) error also appears if power went out before the washer switched itself off, for example in an outage, when the washer was unplugged, or when the circuit breaker trips.
What to check
Confirm the washer is on its own circuit and is not using an extension cord. If the code continues, request service.
3E can be a motor error
On some models 3E is a voltage error, while on others it is a motor error. The user manual for your model says which one it is.
