Samsung washer error codes

Samsung front-load and top-load washers with a digital display. Samsung uses several spellings for the same fault across model years, so we list them together. Models without a display blink their cycle lights instead; those patterns are noted where Samsung publishes them.

Water supply and filling

4C: Not filling with water

The washer asked for water and not enough arrived in time. Samsung’s fixes for this code are all about the water supply.

Doors, lids and drawers

Balance, spin and vibration

UE: Load out of balance

The laundry has bunched to one side, so the drum can’t spin safely. Ur is not a fault: the washer is adding water to rebalance, which makes the cycle longer.

No display? Hot and Warm lights blinking.

Detergent and suds

Too much foam has built up, so the washer pauses to let it settle. The cycle carries on by itself.
