Seeing **EC** on a Samsung dishwasher narrows the problem to **wash-pump issue**. What you do next depends on whether the code is an issue, a normal status/test message, or a model-dependent interpretation. Samsung appliances monitor whether a function reaches an expected state within a certain sequence. When that check fails, the control can store or display a code even though the root cause may sit elsewhere in the same circuit. The recorded display form is **EC**. Search normalization stores it as **EC** while preserving the characters a homeowner actually sees.

Quick answer
Wash-pump issue.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so EC 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
One clue that supports the EC diagnosis is that fluid circulation, drainage, steam generation, or water movement may stop.
One clue that supports the EC diagnosis is that the appliance can pause when expected flow or pressure is not achieved.
One clue that supports the EC diagnosis is that the pump may sound abnormal or fail to run.
The EC display becomes more meaningful if eC appears during the dishwasher function associated with wash-pump issue.
EC can be accompanied by this pattern: 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.
To rule out an accessible cause, verify user-accessible tanks, filters, hoses, and obstructions named in the model instructions.
To rule out an accessible cause, make sure removable water containers are seated correctly where applicable.
To rule out an accessible cause, do not run a pump dry or open pressurized/electrical sections.
The next non-invasive check is to record the code before resetting.
For EC, start by doing this: check water supply, drain path/filter, door, detergent/suds, and visible leaks only when relevant.
Before requesting service for EC, if the code reappears 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. Do not bypass a safety device merely to see whether EC disappears.

When to request repair service
If the owner-accessible checks do not clear EC, A returning pump code after accessible path checks requires pump, wiring, sensor, or control diagnosis. The repair should confirm the monitored function and its feedback before any board or component is condemned.

You can try the one reset Samsung documents for the model, but **EC** returning afterward means the condition still exists. Note the operating stage instead of cycling power repeatedly.
Short owner-accessible checks may be reasonable when the appliance is safe. Persistent **EC**, worsening performance, or any electrical/water/heat hazard is a reason to stop use.
The code alone is not enough to justify a part. **EC** 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 EC** separate from same-looking codes used by other Samsung appliance families.
