The most common Samsung dishwasher error codes are:

OE/OC/0C/oE Water Overflow Error

This error shows when there is too much water in the dishwasher. It could indicate there is a problem with the water inlet valve or main power board assembly. Inspect the drain hose, sink connection, filter, sump pump, and drain. Clean any blockages. If the water continues to fill, replace the inlet valve, or power board.

Check the heater’s wire connections and main power board assembly. If the heater is not working, replace it. If the heater is fine, the problem could be the main power board. Replace if damaged.

HE1 Thermistor Error

This code means the temperature inside the dishwasher is higher than 176F or below 175F. It cn can caused if the heat relay on the main power board is stuck or the thermistor is defective and needs to be replaced.

Flashing “Heavy” Water Leak When you see the word “heavy” flashing on your digital panel, this means there is a water leak. Inspect and tighten or replace the drain hose.
LC/LE Water Leak Error This means there is a water leak under the dishwasher because the drain hoses or pump are faulty. Inspect the hoses, drain pump and tub. Replace any damaged parts.
