Samsung Dishwasher Error Codes

Samsung dishwashers don't spell out what's wrong in plain English — the display cycles through a short code like LE, 5E, or 9E, and it's on you to know what that combination means. Here's every documented Samsung code, what triggers it, and what to check before you book a repair visit.

How to read the display

Most Samsung dishwashers with a digital display show a fault as one or two characters that scroll or flash in the number window — things like 5E, OE, or a lowercase tE. The case matters on a few codes: Samsung uses uppercase and lowercase versions of similar-looking letters (OE vs a fault sometimes written oE, or HE vs HC) to separate related but distinct faults, so check the exact characters against the table below rather than assuming two codes that look alike are the same one.

Older or more basic Samsung models without a text display don't show a code at all — instead a light or a row of indicator lights blinks in a pattern. If nothing resembling a two-character code is showing but the dishwasher is misbehaving, start with Dishwasher Blinking Lights With No Error Code Shown instead of searching for a code that isn't there.

Every Samsung dishwasher code

Code	What it flags	Severity
`LE`	Samsung's leakage error.	High severity	View
`5E / SE`	The dishwasher is having trouble draining water out of the tub within the expected time.	Medium severity	View
`4E / 4C`	The dishwasher isn't getting water at the pressure or temperature it needs during the fill portion of the cycle.	Medium severity	View
`OE`	There is more water in the tub than there should be at this point in the cycle, which is most often a downstream symptom of a drainage problem rather than the fill system adding too much water.	Medium severity	View
`9E`	There isn't enough water in the tub for the dishwasher to run its wash cycle safely.	Medium severity	View
`HE`	The dishwasher's internal temperature is being detected incorrectly, or the heater isn't reaching the expected temperature during the cycle.	Medium severity	View
`tE`	The temperature sensor (thermistor) inside the dishwasher is sending a reading the control board considers out of range, so it can't reliably manage wash and dry temperatures.	Low severity	View
`1E / IE`	On Waterwall-style Samsung dishwashers, this indicates water isn't passing through the filter properly.	Medium severity	View

No code showing — just a problem?

If the display isn't showing anything unusual but the dishwasher still isn't behaving, these cross-brand symptom guides start from what the machine is doing instead of a code on the screen:

Always shut off both power and the water supply before opening the tub, pump, or heating element housing, and if a repair goes beyond checking filters, hoses, detergent, and visible debris, call a licensed technician.
