Samsung Dishwasher Error Codes Explained!

Seeing strange error codes on your Samsung dishwasher can be frustrating, especially when you're not sure what they mean. Most codes point to specific issues, from water supply problems to draining hiccups or sensor faults. Knowing what each code stands for helps you decide if it’s a quick fix or time to call in a pro.

Here’s a practical guide to the most common Samsung dishwasher error codes, what they mean, and the steps you can take to resolve them.

4C or 4E - Water Supply Issue

The 4C or 4E error code pops up when your Samsung dishwasher isn’t getting enough water. This usually means there’s a problem with the water supply, such as a closed valve, kinked hose, or a blocked filter on the inlet hose. Sometimes, low household water pressure can also trigger this code.

Start by making sure the water tap feeding the dishwasher is fully open. Next, check the hose connected to the back of the machine for kinks or bends. Finally, turn off the water and disconnect the hose to inspect the filter at the hose inlet. Clean out any debris, reattach the hose, and try running a cycle again. If the error persists, you might have a faulty inlet valve or an issue with the water pressure in your home plumbing.

5E or SE - Drainage Problem

The 5E or SE code appears when the dishwasher can’t drain water properly. In most cases, this points to a clogged or kinked drain hose, a blocked filter, or a problem with the drain pump. Food scraps and grease can easily clog the dishwasher filter basket, leading to drainage errors.

To fix this, open the dishwasher and remove the bottom rack to access the filter. Pull out and clean the filter under running water, removing any gunk or food particles. Next, check the drain hose at the back for any kinks or obstructions. If you find water pooling at the bottom, it’s a strong sign of a blockage. If cleaning doesn’t help, the drain pump could be at fault and may need professional servicing.

LC or LE - Leak Detected

If your Samsung dishwasher displays LC or LE, the unit’s leak sensor has detected water where it shouldn’t be. This doesn’t always mean a substantial leak - even a small amount of water in the base pan can trigger the sensor. It might happen if you overfill the detergent, load dishes incorrectly, or spill water while cleaning.

First, unplug the dishwasher and pull it out from under the counter, if possible. Check around the base for standing water or dampness. Dry up any water, then let the machine sit unplugged for several hours to allow any moisture in the leak pan to evaporate. If the code returns after powering back on, examine hoses and seals for visible leaks. Persistent leaks may require a technician’s help to replace seals or repair damaged parts.

HE or HC - Heater Error

The HE or HC code signals a problem with your dishwasher’s heating element or its related sensors. You might notice your dishes aren’t drying, or the cycle seems to stop short. This error commonly points to a faulty heating element, a bad temperature sensor, or occasionally a wiring problem in the heater circuit.

If you’re comfortable with basic checks, unplug the machine and inspect the wiring harness around the heater for loose or burnt connections. However, replacing a heating element or sensor requires removing panels and working with electrical components. If you’re not experienced, it’s safest to call in a professional for this repair.

OE, OC, or 0C - Over-Level Water Error

OE, OC, or 0C codes mean the dishwasher has detected too much water inside - either it’s overfilled or the drain isn’t working fast enough. This can result from a malfunctioning water level sensor, a stuck float, or a draining issue causing water to back up.

Make sure the drain hose is correctly installed and not clogged. Sometimes, using too much detergent creates excessive suds, which can fool sensors into thinking there’s too much water. Double-check that the float assembly inside the dishwasher moves freely and isn’t obstructed by debris or a misplaced dish. If none of these steps resolve the error, the water level sensor may be faulty and need replacement.

PE - Half-Load or Zone Wash Error

The PE error code is specific to Samsung dishwashers with a half-load or Zone Wash feature. This error tells you the machine is having trouble with the diverter motor or the sensor that controls which part of the dishwasher receives water. If you rarely use half-load cycles but see this code, it could be a stuck diverter or a wiring issue.

Try resetting the dishwasher by unplugging it for a few minutes. If the problem returns, inspect the spray arms and filters for blockage, because obstructions can sometimes throw off the water distribution. If you still get the PE code, the diverter motor or its sensor may require replacement by a technician.

tE or TE - Temperature Sensor Fault

The tE or TE code means the temperature sensor (thermistor) is malfunctioning, or its wiring is damaged. The dishwasher may stop mid-cycle, refuse to start, or display the error as soon as you try to run a wash.

Inspect the wiring harness connected to the thermistor for signs of damage or loose connections. Sometimes the error is caused by moisture or corrosion on contacts. If tightening or reseating the connection doesn’t help, you’ll likely need a replacement thermistor. This part isn’t expensive, but installation involves removing the dishwasher’s access panels, so consider a technician if you’re unfamiliar with appliance repair.

Other Common Samsung Dishwasher Error Codes

Sensors in Samsung dishwashers can trigger a variety of other codes. For example, the IE or 1E code indicates a clogged water reflector or filter, which is usually fixed by cleaning the filter. The bE code points to a stuck button on the control panel - gently pressing all buttons or wiping them clean can resolve it.

Another code, dE, refers to a door error, which means the door isn’t shutting or latching correctly. Check for any obstructions or worn door latches. If you see the CE code, it usually refers to a communication error between the main control board and other parts, often resolved by unplugging the dishwasher for a few minutes to reset it. For any code not listed here, refer to your user manual, as new models sometimes have different error indicators.
