Samsung Four dasheswhat it means
Four dashes mean the temperature you set does not belong to the mode you selected. Samsung publish this in a form no search engine can read.
Before you start
What this means
This is Samsung asking you to set the temperature again, because the number you chose is not valid for the function you picked. Their explanation is that it appears when you select the Grill function and set a temperature between 50°C and 250°C, or select Normal Cooking mode and set a temperature between Grill 1 and 3, at which point you are asked to reset the temperature with a message and a beep.
In other words, grill settings are grill levels rather than degrees, and conventional settings are degrees rather than levels, and the dashes mean you have crossed them over. The reason this needs a page more than most is structural.
Samsung publish it inside a collapsed accordion whose heading is generated by JavaScript that text extraction throws away — even Samsung’s own analytics label for the section has lost the dashes. Read the page as text and all that survives is a paragraph beginning "this code appears" with no code named, sitting immediately after the preheating entry. Anyone building a code table by scraping will either lose it entirely or attach the explanation to Pr E, which would be badly wrong.
What causes it
| Cause | What is actually happening | How likely |
|---|---|---|
| A degrees temperature was set on the grill function | Samsung name the range explicitly. The grill takes levels rather than degrees, so a number between 50 and 250 is not a setting it recognises. | Common |
| A grill level was set on a conventional cooking mode | The same mistake in reverse. Normal cooking wants degrees, and grill levels one to three are not temperatures it can use. | Common |
What to try yourself
Check which mode you are in. Grill takes levels, usually one to three, and everything else takes degrees.
Set the temperature again in the units that mode expects. Samsung describe the dashes as a prompt to reset the temperature, so that is all it is asking for.
If you meant to grill at a specific temperature, switch to a mode that takes degrees rather than trying to force the number into the grill setting.
Get a qualified appliance engineer to look at your Samsung oven
We do not pass enquiries to a repair firm, so there is no form here. When you book a qualified appliance engineer, tell them the make, the model and the exact code or message on the display, and ask whether they carry parts for this make — that is what turns one visit into a repair rather than a quote.
