Samsung Dishwasher Error Code 9E1

The 9E1 code means the dishwasher has detected an abnormal DC link voltage, either too high or too low, in its internal power circuitry. When this condition is detected, the unit switches to stop mode to protect internal components from damage. The fault can originate from the home's power supply or from a failing internal component. Checking the outlet voltage with a multimeter is the recommended first diagnostic step.

No, you should not attempt to run the dishwasher while the 9E1 error is active. The unit enters stop mode specifically to prevent damage from abnormal voltage conditions. Continuing to operate it before the underlying cause is resolved could damage the motor, control board, or other electrical components. Address the voltage issue first before resuming normal use.

Repair costs depend on the cause. If the issue is a loose outlet connection or a circuit problem, costs could range from nothing for a DIY fix to around $75 to $150 for an electrician visit. If an internal part like the power control board needs replacement, expect parts and labor together to fall in the range of $150 to $350 or more depending on your location and the specific components involved.

In many cases, yes. Start by measuring the voltage at the dishwasher's outlet to confirm it reads approximately 120V AC. If the voltage is low or fluctuating, check for loose wiring at the outlet or a circuit overloaded by other appliances. If the outlet voltage is normal and the error persists, the issue likely involves an internal component such as the control board or wash motor, which may require a technician to diagnose safely.

A reset may temporarily clear the error code, but it will return if the underlying voltage problem is not corrected. To reset, you can power cycle the dishwasher by turning off the circuit breaker for one to two minutes and then restoring power. If the 9E1 code reappears after the reset, the root cause, such as low outlet voltage or a failing component, still needs to be diagnosed and repaired.
