Seeing **9E1** on a Samsung dishwasher narrows the problem to **abnormal / excessive voltage error**. What you do next depends on whether the code is an issue, a normal status/test message, or a model-dependent interpretation. The exact stage when the code appears can be as important as the characters themselves. Note whether it happens at startup, during fill, heating, cooling, draining, spinning, drying, or after a power event. The recorded display form is **9E1**. Search normalization stores it as **9E1** while preserving the characters a homeowner actually sees.

Quick answer
Abnormal / excessive voltage error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so 9E1 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Signs
Symptoms you may notice
The 9E1 display becomes more meaningful if the appliance can stop, restart, or refuse a high-load function.
On affected Samsung dishwasher models, the code can appear after a surge, brownout, outage, incorrect supply, or frequency problem.
Depending on the exact model, some models preserve the display even when one required power leg or voltage range is abnormal.
Depending on the exact model, 9E1 appears during the dishwasher function associated with abnormal / excessive voltage error.
On affected Samsung dishwasher models, the cycle may stop, drain, fail to fill/heat, or repeat a stage.

Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
The next non-invasive check is to confirm the breaker has not tripped and the appliance is connected as specified by Samsung.
With 9E1 recorded, if the event followed an outage or surge, perform only the documented one-time power reset.
Before opening any service area, do not perform live mains-voltage measurements unless qualified.
Before opening any service area, stop if breakers trip repeatedly, plugs/outlets overheat, or there is arcing.
With 9E1 recorded, record the code before resetting.
Before requesting service for 9E1, verify water supply, drain path/filter, door, detergent/suds, and visible leaks only when relevant.
Important safety warning. When working around a dishwasher that shows 9E1, keep the checks external and non-invasive. Stop use for active leakage near electrical parts, burning smell, or repeated breaker trips. Do not defeat leak or door-safety switches.

When to request repair service
Persistent power/voltage codes need the household supply and appliance power/control circuits checked safely before parts are replaced. If 9E1 keeps returning, record the stage at which it reappears so the technician can test the abnormal / excessive voltage error path instead of replacing parts by guesswork.

Resetting can clear a temporary state, not a persistent issue. If **9E1** comes back, preserve the code and move to the safe checks or model-specific service path.
That depends on the accompanying symptom. A code with no safety hazard may allow a short diagnostic check, but **9E1** should not be ignored if performance is deteriorating or the display keeps returning.
No. **9E1** tells you which condition or check the control detected. The same display can result from the named component, its wiring, a connector, a supply/airflow/water condition, or the control that reads it.
The same-looking code can be reused on another Samsung appliance family or reformatted by region/model year. Match the appliance type and exact model before applying a meaning. This page therefore keeps **Dishwasher 9E1** separate from same-looking codes used by other Samsung appliance families.
