Samsung Dishwasher Error Codes

The Samsung dishwasher OC error code (also shown as 0C or OE) shows that the unit has spotted extreme amounts of water inside. This could be due to:

• A congested drain filter
• A blocked or kinked drain hose
• A damaged water level sensor

Common Causes of the OC Code

1. Blocked Drain Filter – Clean the dishwasher’s drain filter to eliminate food wreckages.
2. Drain Hose Issues – Examine the drain pipe for blockages and guarantee it is accurately connected.
3. Water Level Sensor Malfunction – If you clean it and don’t resolve the issue, a defective sensor needs to be replaced.

Whirlpool dishwashers also display error codes. Some common Whirlpool dishwasher diagnostic codes include:

• F2 E2 – Stuck button
• F3 E1 – Thermistor/OWI sensor failure
• F6 E4 – Float switch issue

If you have a Whirlpool dishwasher, refer to the user manual for troubleshooting specific to your model.

Other Common Samsung Dishwasher Errors

Stuck Relay

A stuck relay can lead to electrical issues and prevent the dishwasher from working. When you reset the dishwasher, it may temporarily fix the problem, but professional repair is recommended.

Memory Corruption

A power surge or software bug can cause memory corruption in your dishwasher’s control board. A factory reset may be required.

Stuck Button

If a button on the control panel is jammed, you may see an Error code associated with button failure. We recommend you to clean the panel and press each button to free any that are stuck.

Communication Error with Circulation Pump

A circulation pump communication error doesn’t let the water move through the dishwasher. If you see this issue, call a professional to inspect the pump.

Water Fill Problems

If your dishwasher is not filling properly, check the water inlet valve and water pressure to guarantee they meet the manufacturer’s requirements.

Suds or Air in Pump

When you use a big amount of detergent, it can create excessive suds and lead to an LC Samsung dishwasher code. Run an empty cycle to clear the excess detergent.

Flow Meter Problem

A faulty flow meter may incorrectly measure water levels and cause error codes. You should replace the flow meter.  

Heating Element Problems

If your dishwasher isn’t heating water properly, the heating element or thermistor sensor may need repair.

Drain Problems

Drainage issues cause several error codes, including Samsung dishwasher code OC and 5C. We recommend you clean the drain hose and filter on a regular basis.
