What does Samsung 9C1 mean?

Power supply (voltage) error: there is an irregularity in the electrical current reaching the washer.

Basic checks first: jump to safe DIY steps Equipment type: washing machine
How it shows: Washer display shows 9C1

Likely causes

  • The washer shares its circuit with other loads instead of having its own
  • The washer is plugged into an extension cord
  • PF only: the power went out before the washer powered itself off (an outage, the washer being unplugged, or a tripped breaker)
  • A washer used outside its country of origin, where power grids and regulations differ
  • On some models 3E means a motor error, not a power supply error

How to fix 9C1: safe DIY steps

  1. Confirm the washer is on its own circuit
  2. Plug it straight into the wall outlet, not into an extension cord
  3. If PF appeared after a power cut, an unplugged cord or a tripped breaker, that is what the code is reporting: power was lost before the washer switched itself off
  4. If your display shows 3E, check your user manual to see whether it is a power supply error or a motor error. For a motor error Samsung's basic steps are to power off for 2 to 3 minutes, power back on and restart the cycle
  5. If the code continues, request Samsung service
Safety firstUnplug the washer (or switch off its breaker) and close the water taps before you reach behind it, handle hoses or open a filter. Water left from a recent hot cycle can be very hot, so let it cool first. Never bypass the door lock. Motor, pump, valve, sensor and control-board repairs belong to a qualified appliance technician.

Capacitors can hold a charge after the power is off. Safety terms.

When to call a pro

Samsung says to request service if the code continues after the washer is on its own circuit without an extension cord.
