The **bE3** display on a Samsung dishwasher points to **touch-control communication/input error**. Treat it as a diagnostic direction rather than a parts order: operating conditions, wiring, sensors, actuators, and control electronics can overlap. A display code is evidence from the control system, not a component test result. That distinction matters because a connector, supply condition, obstruction, or feedback signal can mimic a failed component. The recorded display form is **bE3**. Search normalization stores it as **BE3** while preserving the characters a homeowner actually sees.

Quick answer
Touch-control communication/input error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so BE3 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
The **bE3** display on a Samsung dishwasher points to **touch-control communication/input error**. Treat it as a diagnostic direction rather than a parts order: operating conditions, wiring, sensors, actuators, and control electronics can overlap. A display code is evidence from the control system, not a component test result. That distinction matters because a connector, supply condition, obstruction, or feedback signal can mimic a failed component. The recorded display form is **bE3**. Search normalization stores it as **BE3** while preserving the characters a homeowner actually sees.
Signs
Symptoms you may notice
A symptom that fits bE3 is that the appliance may lose communication between control boards, display, inverter, or other electronic modules.
On affected Samsung dishwasher models, controls can become unresponsive, a feature can stop, or the code may appear after power-up.
When the bE3 condition is present, intermittent operation can occur if a connection or power condition is unstable.
On affected Samsung dishwasher models, bE3 appears during the dishwasher function associated with touch-control communication/input error.
One clue that supports the bE3 diagnosis is that 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.
Before requesting service for bE3, power the appliance off once using the documented method, then restore power and see whether the code reappears.
With bE3 recorded, record whether the issue followed an outage, update, move, or service event.
A safe owner-level check is to do not reseat internal live connectors unless qualified to follow the exact service procedure.
With bE3 recorded, record the code before resetting.
To rule out an accessible cause, check water supply, drain path/filter, door, detergent/suds, and visible leaks only when relevant.
With bE3 recorded, if the code returns after the supported owner checks, request model-specific diagnosis.
Important safety warning. Stop use for active leakage near electrical parts, burning smell, or repeated breaker trips. Do not defeat leak or door-safety switches. For bE3, stop troubleshooting immediately if the symptom crosses into a safety hazard rather than a normal diagnostic condition.

When to request repair service
A returning communication/electronic-control code can require harness, connector, board power-supply, firmware, or module testing. If bE3 keeps returning, record the stage at which it reappears so the technician can test the touch-control communication/input error path instead of replacing parts by guesswork.

Book a specialist visit for a clear estimate and approval before any repair.
You can try the one reset Samsung documents for the model, but **bE3** returning afterward means the condition still exists. Note the operating stage instead of cycling power repeatedly.
Do not keep operating the appliance through a hazardous symptom just to see whether **bE3** clears. If there is heat, water, electrical, gas, or food-safety risk, stop and arrange diagnosis.
The code alone is not enough to justify a part. **bE3** should narrow testing to the affected function; the final cause still has to be verified on the exact model.
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 bE3** separate from same-looking codes used by other Samsung appliance families.
