What it means
So rule out the water supply first: make sure the cold hose isn't connected to a hot supply (see 4C2). If the supply is right and the code comes back, it's the heater.
What to check, in order
- Check the cold supply
Make sure the cold tap is open and the cold hose isn't kinked or swapped with the hot.
- Restart it
Switch the washer off, wait a minute, switch it back on and start a new cycle.
When to call an engineer
If the code comes back. The heater runs on mains power inside the machine, and Samsung says to contact its service centre.
A repair visit will usually check the heating element, its temperature sensor and the wiring back to the control board.
- Note the model and serial number. They're on a label inside the door, around the door frame or on the back.
- Write down the exact code, and what the appliance was doing when it appeared.
- Check whether it's still under warranty. If it is, the repair may cost you nothing.
Good to know
- On some US and Australian models, 6E points at the motor or spin rather than the heater. If yours is one of those, see 3E.
