Samsung Washer Error Code HE3

HE3 on a Samsung washer indicates a heater error in the steam function. The control board has detected that the steam heater is not operating normally, so the steam cycle has been disabled. This code applies only to steam-capable models, and the first step is confirming your unit actually has a steam function before proceeding with component testing.

The washer will typically disable the steam function when HE3 is active, but standard wash cycles may still operate. Running the machine without resolving the fault is generally low risk for non-steam cycles, but continuing to attempt steam cycles with a faulty heater could cause further electrical issues. It is best to address the fault before relying on steam features again.

A reset may temporarily clear the HE3 code from the display, but the error will return as soon as the washer attempts to use the steam function again if the underlying fault has not been corrected. Resetting is useful for confirming whether the fault is intermittent, but it is not a fix. The steam heater and associated wiring must be properly diagnosed and repaired to permanently resolve the error.

Some basic checks, such as inspecting wiring connectors and confirming the machine is a steam model, can be done by a confident DIYer. However, replacing the steam heater element or thermal fuse involves disassembling internal panels and working near electrical components, which is better suited to a technician. If you are not comfortable with appliance disassembly, professional service is the safer option.

Repair costs depend on the failed component. A replacement steam heater element typically costs in the range of $30 to $80 for the part alone. If professional labor is added, total repair costs generally range from $100 to $250 depending on local rates and accessibility of the component. A control board replacement, if needed, will be at the higher end of the cost range.
