Samsung Dishwasher Error Codes
Samsung dishwashers show a two-character code when water leaks into the base, fills too high or doesn’t come in fast enough. Many codes come in pairs that mean the same thing, such as LC and LE or 4C and 4E, because older displays show the letter differently.
Choose your code below for its meaning, the checks you can do yourself and the point where service should take over.
- LC Leakage error: the leak sensor in the base has detected moisture where it doesn't belong. On Waterwall models a blocked water reflector can also cause it.
- OC Over-level water error: the dishwasher detected excessive water in the tub, usually because water isn't draining or is flowing back in.
- 4C Water supply error: the dishwasher can't take in enough water, usually because of low pressure, a closed valve or a blocked supply line.
- 5C Drain error: the dishwasher can't drain water from the tub properly, usually because of a clogged filter, a kinked or blocked drain hose or debris in the drain pump.
