For the Samsung Washer families covered by the source set, **E8** means **water temperature / hot-cold supply error**. The first useful step is to preserve the exact characters and model number before power cycling the appliance. Samsung uses overlapping code conventions across model years and regions. This page keeps the appliance context attached to the code so a same-looking string from another product family is not misapplied. The recorded display form is **E8**. Search normalization stores it as **E8** 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 E8 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

What this code means
For the Samsung Washer families covered by the source set, **E8** means **water temperature / hot-cold supply error**. The first useful step is to preserve the exact characters and model number before power cycling the appliance. Samsung uses overlapping code conventions across model years and regions.

Signs
Symptoms you may notice
While E8 is active, the appliance can stop or limit the affected function when the code is detected.
Depending on the exact model, the same code may return at a repeatable stage of operation.
E8 can be accompanied by this pattern: other symptoms depend on the model and the subsystem named by Samsung.
A symptom that fits E8 is that e8 appears during the washer stage associated with water temperature / hot-cold supply error.
The E8 display becomes more meaningful if the cycle may 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.
As an external check for E8, record the exact code, model number, and operating stage before resetting power.
Before opening any service area, complete only the owner-accessible checks described in the model manual.
For E8, start by doing this: do not replace parts solely from a display code when wiring, conditions, or control feedback can create the same result.
Before requesting service for E8, 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.
Before requesting service for E8, power-cycle once only where Samsung's guidance recommends it; if the same code returns, move to model-specific diagnosis.
Important safety warning. Disconnect power and stop use for active leakage near electrical parts, smoke, burning smell, or repeated breaker trips. Do not bypass a safety device merely to see whether E8 disappears.

When to request repair service
Once E8 has returned after the safe checks, If the code returns after the documented basic checks, request model-specific diagnosis of the affected subsystem. Preserve any accompanying noise, water level, temperature, or operating-stage details for the technician.

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 **E8** display should be treated as diagnostic evidence, not as a reason to keep rebooting the appliance.
Do not keep operating the appliance through a hazardous symptom just to see whether **E8** 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. **E8** 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 **Washer E8** separate from same-looking codes used by other Samsung appliance families.
