Samsung Dishwasher Error Code CE — What It Means & How to Fix It

What Does This Error Mean?

The CE error means your Samsung dishwasher has a communication failure. Two internal components have lost contact with each other. This is usually between the main control board and the display or motor.

Affected Models

DW80R9950UG
DW80R5061US
DW80K5050US
Most Samsung built-in dishwashers

Common Causes

A wiring harness connector has come loose inside the machine
The main control board (PCB) has failed or been damaged
A power surge disrupted communication between components
Moisture or corrosion has damaged an internal connector
A firmware glitch is causing a false communication fault

How to Fix It

Turn off the dishwasher and unplug it from the wall outlet.

Wait 10 minutes before plugging it back in — this allows the board to fully discharge.
Plug it back in and attempt to start a normal wash cycle.

A power reset clears temporary communication glitches about 20–30% of the time.
Check your circuit breaker panel for any tripped kitchen breaker.

A partial power loss can cause CE — reset the breaker and try again.
If CE persists after two resets, stop using the dishwasher.

Running with an active CE error can cause further damage to the control board.
Contact Samsung support or a certified appliance technician.

Mention the CE code specifically — they will know what diagnostics to run.

When to Call a Professional

CE is usually not a DIY fix — internal wiring and boards are involved. A technician can diagnose whether it's a loose wire or a failed board. Main control board replacement typically costs $200–$400. Always get a quote before authorising any repair.

Frequently Asked Questions

Can a power reset fix the CE error on my Samsung dishwasher?

Sometimes, yes. A soft reset clears temporary communication faults. Unplug for 10 minutes, then restart. If CE comes back within one cycle, the hardware needs attention.

Is CE a sign my dishwasher is beyond repair?

Not necessarily. A loose wire harness is a cheap fix — under $50 with labor. Only if the main control board has failed does the repair become expensive. A technician can tell you which scenario you're facing.

How long does a Samsung dishwasher control board last?

On average, 7–12 years under normal use. Power surges and moisture are the biggest threats to control boards. Using a surge protector on your kitchen circuit can extend its life.
