If a Samsung washing machine shows **4E2**, the verified Samsung meaning in this research set is **water temperature / hot-cold supply error**. Use the code to narrow the diagnosis, then confirm the exact model because code scope can change by product generation or region. 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 **4E2**. Search normalization stores it as **4E2** while preserving the characters a homeowner actually sees.

Quick answer
Water temperature / hot-cold supply error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so 4E2 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
If a Samsung washing machine shows **4E2**, the verified Samsung meaning in this research set is **water temperature / hot-cold supply error**. Use the code to narrow the diagnosis, then confirm the exact model because code scope can change by product generation or region. 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 **4E2**. Search normalization stores it as **4E2** while preserving the characters a homeowner actually sees.
Signs
Symptoms you may notice
On affected Samsung washing machine models, the appliance can stop or limit the affected function when the code is detected.
The 4E2 display becomes more meaningful if the same code can return at a repeatable stage of operation.
While 4E2 is active, other symptoms depend on the model and the subsystem named by Samsung.
The 4E2 display becomes more meaningful if 4E2 appears during the washer stage associated with water temperature / hot-cold supply error.
The 4E2 display becomes more meaningful if the cycle can pause, stop, retry, drain, or refuse to advance until the condition is cleared.

Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
With 4E2 recorded, record the exact code, model number, and operating stage before resetting power.
The next non-invasive check is to complete only the owner-accessible checks described in the model manual.
As an external check for 4E2, do not replace parts solely from a display code when wiring, conditions, or control feedback can create the same result.
The next non-invasive check is to record the code and the cycle stage where it appears.
The next non-invasive check is to verify owner-accessible water supply, drain hose/filter, load balance, door, detergent, or power only when relevant.
A safe owner-level check is to power-cycle once only where Samsung's guidance recommends it; if the same code returns, move to model-specific diagnosis.
Important safety warning. When working around a washing machine that shows 4E2, keep the checks external and non-invasive. Disconnect power and stop use for active leakage near electrical parts, smoke, burning smell, or repeated breaker trips.

When to request repair service
If the owner-accessible checks do not clear 4E2, If the code returns after the documented basic checks, request model-specific diagnosis of the affected subsystem. The repair should confirm the monitored function and its feedback before any board or component is condemned.

Seeing this code on your Samsung appliance?
Book a specialist visit for a clear estimate and approval before any repair.
A single documented power reset can help after an external condition or power event is corrected. If **4E2** returns at the same stage, repeated resets only erase useful evidence and do not repair the cause.
Short owner-accessible checks may be reasonable when the appliance is safe. Persistent **4E2**, 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 **4E2** 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 **Washer 4E2** separate from same-looking codes used by other Samsung appliance families.
