What 5C means on a Samsung washer dryer
Drain fault: water is not draining from the machine.
Meaning checked by NAC's engineers, 9 November 2026.
What our engineers say
On a Samsung washer dryer, code 5C is a drain fault. It means water is not draining from the machine, so you may find it stops partway through, will not rinse properly or ends a cycle with water still inside.
Engineers sometimes find fluff or lint wrapped around the moving part inside the drain pump, which stops it pushing the water out. Sometimes the pump itself has failed, perhaps sticking so that it only starts with a nudge. Now and then the machine is fine and the blockage is further along, in the household waste pipe it drains into.
An engineer will usually check whether the pump is blocked, whether it is working properly, and whether water can get away through the waste pipe. Clearing a blockage from the pump or the waste pipe often puts it right on the first visit. If the pump has failed, they replace it, and the new pump often has to be ordered and fitted at a second visit. Afterwards they run the machine through a rinse and spin to make sure it drains without leaking.

Before you check anything yourself
- Switch the washer dryer off and unplug it, or turn it off at the isolator switch, before you touch anything. Our guide to safely isolating an appliance walks you through it.
- An error code tells you where to look, not that it's safe to take the washer dryer apart. Don't remove panels or covers to get at the parts it points to: that's an engineer's job.
- If it involves the mains supply, sealed parts, or you're not confident at any point, stop and book a qualified engineer rather than risk injury or further damage.
