If the Samsung WF50BG8300 fills to too little water, the cause is either the supply or the water level sensor. The washer detects the weight of the load and sets its own water level, so a small load legitimately gets less water. But a drum that stays nearly empty on a big load means low pressure, a clogged mesh filter or the sensor: 1C is Samsung's code for checking the water level sensor, and the fix is to power off for 2 to 3 minutes and try again.
Differential
Likely causes of “Samsung front-load or top-load washer uses very little water”, and how to tell them apart
- 1
A small load that the washer correctly gives less water
What separates it Low water for one or two items and normal for a full load
How to confirm Compare with a full mixed load; the washer sets the level from the detected weight
- 2
Low pressure or a clogged mesh filter
What separates it Water trickles in and the fill takes a long time
How to confirm Clean both mesh filters and check the taps and pressure (20 to 116 psi)
- 3
A kinked or frozen hose
What separates it The fill stalls and the display may show 4C
How to confirm Straighten the hoses and check the room temperature against 32 F (0 C)
- 4
The water level sensor
What separates it 1C shows and the level is wrong on a full load
How to confirm Power off for 2 to 3 minutes and try again; if 1C returns, call service
Before you touch a setting
Record this first — changing settings destroys the evidence
- The load size and the water level you see in the window
- Whether the display shows 1C, 4C or another code
- How strongly water flows from each tap into a bucket
Try in this order
0 of 5 completedCompare with a full load
ReversibleThe washer detects the weight of the items and adjusts water. Run a cycle with a full mixed load and see whether the level is right.
Check taps, hoses and pressure
ReversibleFully open both taps, straighten the hoses and confirm the pressure is between 20 and 116 psi (137 to 800 kPa).
Clean the mesh filters
ReversibleWith the taps closed, remove each hose, pull out the mesh filter with pliers, clean it in water and refit it.
Read the code
Reversible1C = check the water level sensor: power off for 2 to 3 minutes, power on and try again.
Call service if 1C persists
ReversibleThe manual has no further consumer fix for the level sensor, so a repeating 1C is a technician's job.
Model-specific
What is true of this model and not of its siblings
- Code
- 1C = water level sensor; 4C = water supply line; OC = overflow.
- Automatic level
- Water level, wash time, rinses and spins adjust to the detected weight on many cycles.
- Tools and supplies
- A bucket for the flow test, pliers for the mesh filters and a flashlight to read the display code.

Stop boundary
When this stops being a self-service repair
- !If 1C returns after a power-off wait of 2 to 3 minutes, the level sensor or control needs service
- !If the level is too high instead, close the taps and use the overflow steps: OC means water may overflow

Exact questions
Common questions
Why is the water level low in my Samsung WF50BG8300?+
The washer sets the level from the load weight; a low level on a full load points to supply or the sensor.
Does the level change during the cycle?+
The washer may adjust water, time, rinses and spins according to the load on some cycles.
Do frozen hoses matter?+
Yes. Below 32 F (0 C) the supply can freeze; use warm water on the hose and tap.
Does Cold use less water?+
The manual says Cold (Level 1) uses only cold water without the heater; it does not describe a lower level.
When to call service?+
When 1C returns after the power-off wait.
Does the washer measure the load?+
Yes, it detects the weight of the items and adjusts the optimal water level, wash time, rinse counts and spin counts on most cycles.
Do bedding loads change how the washer runs?+
Bedding limits the recommended maximum spin level to 2 or 3 and the load to 7 lb (3.0 kg) or less; the wash time may lengthen.
Can hot water trouble look like low water?+
If the hot supply is missing, warm cycles are cooler but the level is set by the sensor; check the hoses are on the correct taps.
How do I check the hoses?+
Fully open the taps, make sure the supply hose is not frozen, kinked or clogged and that there is sufficient water pressure.
What does 4C look like next to a low level?+
4C points to the water supply line: check the connection to the water lines and taps, power off for 2 to 3 minutes and try again.
How do I check the level sensor code?+
Read the display: 1C means check the water level sensor; power the washer off for 2 to 3 minutes, power it on and try again.
Does draining automatically clear low water?+
Depending on the model the drain system may drain water automatically after a code, and the Power and Start/Pause buttons may be disabled during that process.
Can the mesh filters cause a low level?+
A clogged mesh filter restricts the fill and shows 4C; clean the mesh filters once or twice a year, more often for an aged water system or a well.
What should the pressure be?+
20 to 116 psi (137 to 800 kPa) per the specification sheet; a weak stream into a bucket points at the house supply.
