Can't read the code? Draw it.

On a seven-segment display 5 and S look identical, O and 0 too, and one dead bar turns an E into an F. Tap the bars that are lit on your display, and you'll see every code on this site that could look like that.

Try:

Keyboard: arrow keys move between bars, Space turns one on or off. Short codes can go in any of the four places.

Start with the bars you're sure of. Matches appear here as you go, and codes that differ from your drawing by one bar show up too, in case a segment has died.

Look-alikes to watch for

Seven bars can only draw so much. These are the pairs that cause most wrong look-ups.

Tips for reading a display

  • Codes that alternate or scroll, like F8 then E1, are one code: F8E1.
  • A flashing code is still a code. Take a video with your phone and pause it.
  • Some displays show the code upside down to you if you read them from above. Read it from in front of the machine.
  • Codes on models without a display blink a light instead. Count the blinks, then check your manual.
