Samsung dishwasher fault codes
Samsung call these information codes rather than fault codes, and they come as a digit or letter followed by C — 4C, 5C, LC. Older machines show the same faults with an E, and Samsung UK treat the two as the same thing. Samsung publish one long code list for the UK plus a dedicated page for the three water codes, and their manuals carry a shorter table; where the sources disagree, and on the leak code they do, we say so on the page.
Where the code shows on a Samsung
Samsung UK’s own documentation treats the C and E forms as one code — their dedicated support page is titled for "5C/5E, 4C/4E, and LC/LE", and the main code list groups 3C with 3E, HC with HE, tC with tE and so on. What Samsung have never actually published is a statement that C replaced E on newer machines, so we are not going to claim they did. Samsung also note that only models with a digital display show a code as such; machines without a display use blinking lights instead, and Samsung UK publish no decoder for the blink patterns. Be careful with search results from Samsung’s American site, because it does not follow the same rule: it lists 3E as a high temperature water supply error separate from 3C, lists HE as a heater error separate from HC, and publishes a 1E code that does not appear on the UK site at all. For a UK machine the UK grouping is the one to trust.
How to reset a Samsung
Samsung do not publish a reset sequence. Their pattern is to clear the cause and then power the machine off at the wall or the breaker for a set time before retrying, and the time varies by code on their UK list: one minute for 3C and 9C1, five minutes for HC, 9C2 and tC, ten minutes for the button codes bC2 and AC6, and at least thirty seconds for DC and PC. Where a code persists their instruction is to contact support. On the leak code LC the manual tells you to isolate first — close the water valve and switch the dishwasher’s breaker off at the consumer unit — and on HC it asks for the same only if an empty test cycle brings the code back.
Most common Samsung faults
The Samsung codes people look up most.
- 5CGet it checkedDrain fault. Samsung describe the detection precisely — the control expected the water level to fall and saw no change.
- 4CGet it checkedWater supply check. Samsung’s checks are the valve, the supply and a frozen or clogged inlet, and their manuals give the pressure and temperature the supply has to meet.
- LCStop — call an engineerLeak detected. Samsung publish three different answers to this code across three official UK sources, and only one of them isolates the machine.
- HCGet it checkedHigh temperature check. Samsung’s first instruction is a test cycle with the machine empty, and the breaker only comes into it if the code returns.
