Samsung H01 washing machine: what it means & what to check

Stop using it for now. Carrying on with this fault risks further damage or a leak. Switch it off at the wall until it has been looked at.

What H01 actually means

The machine has stopped because the water is heating wrongly \u2014 the temperature is either not what it should be, or it is climbing far faster than expected.

Samsung machines monitor the wash water with a temperature sensor while the heater is on. If the readings are out of step with the programme \u2014 typically shooting up too fast \u2014 the control board shuts the heating down and shows this code rather than risk overheating the load or the drum. You'll usually see it part-way through a warm or hot wash, often with the drum full of water.

What H01 looks like on a Samsung washing machine

Most people find this page having searched for what the machine is doing rather than the code itself. On a Samsung washing machine, H01 usually shows up as one or more of these:

Machine not draining
Water left in the drum at the end of the cycle
Stops mid-cycle full of water
Standing water in the bottom
Not heating the water
Washing coming out cold
Cycle takes far longer than it should
No function at all

Recognise any of those? That is this fault, and the rest of this page explains what causes it and what you can check yourself.

What usually causes it

Faulty water temperature sensor giving false readings
Heating element failing or shorted
Wiring connection to the sensor or heater has gone bad
Control board misreading the temperature signal

What you can safely check yourself

Work through these in order. Anything beyond this — panels off, testing parts, anything to do with the wiring — is an engineer's job, and not one to attempt with the machine plugged in.

Turn the machine off at the wall for a minute, then switch back on and try a cold wash \u2014 if a cold cycle completes normally, that points at the heating side.
Cancel the cycle and drain the machine using a rinse or spin programme before leaving it standing full of hot water.
