H1

How to Fix It

1. Do not touch the washer for at least 30 minutes. The H1 error means dangerously hot water may be inside. Allow everything to cool completely before opening the door or touching any parts.

   This is a genuine safety concern. Scalding water can cause serious burns. Wait the full 30 minutes even if the error has cleared.

2. Once cool, power the washer off completely and unplug it from the wall outlet. Wait 5 minutes, then plug it back in and power it on. Try running a short cold wash cycle to see if the error returns.

   If the H1 error does not return on a cold water cycle, the heating element circuit is the most likely suspect.

3. Check that the hot and cold water hoses are connected to the correct inlets on the back of the washer. Hot water (marked H or HOT) goes to the hot inlet. Cold water (marked C or COLD) goes to the cold inlet. Reversed hoses can cause overheating.

   This is an easy mistake to make after moving the washer or replacing hoses. Both hose fittings look identical.

4. If the hoses are correct and the error returns, the thermistor (water temperature sensor) likely needs testing or replacement. This component is inside the drum area and requires disassembly.

   A Samsung service technician can test the thermistor resistance with a multimeter. The correct resistance varies by temperature — your technician will have the specifications.

5. If the thermistor tests fine but H1 keeps appearing, the heating element itself may be shorted and running continuously. This requires replacement by a technician.

   Never bypass or ignore the H1 error. Continuous overheating can damage the drum, door seal, and plastic components — and in rare cases poses a fire risk.
