For the Samsung Dishwasher families covered by the source set, **bC2** means **button / touch-control error**. The first useful step is to preserve the exact characters and model number before power cycling the appliance. The useful diagnostic value of the code is the subsystem it identifies. A good repair process confirms the symptom, checks the accessible external conditions, and then follows the model-specific circuit only if the display returns. The recorded display form is **bC2**. Search normalization stores it as **BC2** while preserving the characters a homeowner actually sees.

Quick answer
Button / touch-control error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so BC2 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
On affected Samsung dishwasher models, one or more controls can not respond normally or may appear held down.
Depending on the exact model, the appliance can beep, cancel, or refuse to start while the input is detected.
The bC2 display becomes more meaningful if the code may return immediately when the control panel self-check runs.
bC2 can be accompanied by this pattern: bC2 appears during the dishwasher function associated with button / touch-control error.
On affected Samsung dishwasher models, the cycle can stop, drain, fail to fill/heat, or repeat a stage.
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
With bC2 recorded, make sure no object, moisture, cleaner residue, or protective film is pressing the control.
Before opening any service area, dry and clean the exterior control surface without flooding it.
The next non-invasive check is to try the documented Control Lock/Child Lock procedure if relevant.
For bC2, start by doing this: do not open the panel to bypass a stuck key.
With bC2 recorded, record the code before resetting.
Before opening any service area, 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 bC2, 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
If the control is clean and unobstructed but the input code returns, the keypad, harness, or control board may require diagnosis. A repeatable bC2 event is more useful diagnostically than repeated resets, because it shows when the button / touch-control error check is failing.

Seeing this code on your Samsung appliance?
Book a specialist visit for a clear estimate and approval before any repair.
One controlled restart is reasonable after correcting an obvious external issue. A recurring **bC2** display should be treated as diagnostic evidence, not as a reason to keep rebooting the appliance.
Short owner-accessible checks may be reasonable when the appliance is safe. Persistent **bC2**, worsening performance, or any electrical/water/heat hazard is a reason to stop use.
Not automatically. Samsung error codes are diagnostic indicators, not part numbers. Confirm the circuit around **bC2** before replacing anything.
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 bC2** separate from same-looking codes used by other Samsung appliance families.
