Error Message
Probable Cause
Solution
The foot controller was pressed (or the start/
stop button was pressed if the foot controller is
not connected) and the reverse/reinforcement
stitch button was pressed while the presser foot
is raised.
Lower the presser foot lever before continuing
the operation.
A stitch other than the buttonhole or bar tack
stitch was selected and the foot controller was
pressed (or the start/stop button was pressed if
the foot controller is not connected) while the
buttonhole lever is lowered.
Raise the buttonhole lever before continuing
the operation.
The buttonhole or bar tack stitch was selected
and the foot controller was pressed (or the start/
stop button was pressed if the foot controller
is not connected) while the buttonhole lever is
raised.
Lower the buttonhole lever before continuing
the operation.
The reverse/reinforcement stitch button or
needle position button was pressed while the
bobbin winder shaft is moved to the right.
Move the bobbin winder shaft to the left before
continuing the operation.
The start/stop button was pressed while the
foot controller was connected.
Disconnect the foot controller, and then press
the start/stop button. Otherwise, operate the
machine by using the foot controller.
The motor locked up because the thread
became tangled, or the needle bent and thus
hit the needle plate.
Clean the race to remove the tangled thread
(page 60).
Check the needle. If the needle is bent or
broken, replace the needle (page 21).
If both of the above fail, refer to “Error message
“E6” appears in the LCD” (page 65).
The machine may be malfunctioning.
Contact your nearest authorized service center.

is performed you will hear two or four beeps (only for models equipped with the operation beep).
■
If a key is pressed (correct operation)
One beep sounds.
■
If an incorrect operation is performed or a non-functioning key is pressed
Two or four beeps sound.
■
If the machine locks up, for example, because the thread is tangled
The sewing machine beeps for four seconds and the machine automatically stops. Be sure to check for the
cause of the error, and correct it before continuing to sew.
