Affected Models
- WF56H9100AG
- WF45R6100AW
- WF50R8500AV
- Samsung front-load washers with steam functions
Common Causes
- Faulty water temperature sensor (thermistor) sending incorrect readings
- Heating element stuck in the ON position and not shutting off
- Hot water supply connected to both hot and cold inlets by mistake
- Control board malfunction causing the heater to run too long
- Steam function failure creating excessive internal heat
How to Fix It
-
Stop the cycle immediately and do not open the door yet.
The drum may contain very hot water. Let the washer cool down for at least 15 minutes before proceeding.
-
Unplug the washer from the wall outlet.
This cuts power to the heating element and lets everything cool safely.
-
Check your water supply hoses at the back of the washer.
Make sure the hot water hose is connected to the HOT inlet and cold to COLD. Swapped hoses are a common cause of overheating.
-
Plug the washer back in after 15 minutes and run a cold water cycle.
If the Hd error does not return on a cold cycle, the issue may be related to hot water supply or the heating element control.
-
If the error returns, schedule a service call.
The thermistor or heating element needs professional testing and likely replacement.
When to Call a Professional
The Hd error almost always requires a technician. A stuck heating element or faulty thermistor are not safe DIY repairs. Contact Samsung support or a licensed appliance repair service. Repairs typically cost $150–$300 depending on the part.
Frequently Asked Questions
Is the Hd error dangerous?
It can be if the heating element is stuck on. Overheated water can damage clothes and internal seals. The washer's safety cutoff prevents the worst outcomes, but you should not ignore this error. Get it inspected promptly.
Can I fix the Hd error myself?
The water supply hose check is safe to do yourself. Beyond that — testing a thermistor or replacing a heating element involves opening the washer and working near electrical components. This is best left to a qualified technician.

If your washer is within the standard 1-year Samsung warranty, yes. Samsung also offers an extended warranty on some components. Call Samsung support at 1-800-726-7864 with your model number to check coverage.
