Bernina 430 aurora will not sew, beeps when pedal is pushed...
I was sewing fine & then I got the oil light so I stopped and cleaned the fuzz and dropped a drop of oil in the hook race. Rethreaded & now all I get is a beep when I press the pedal. I think this is a simple problem but there is nothing in the instruction book about this.

It's an older mechanical machine, but they are real workhorses. Just keep it clean and oiled (only fresh, good quality sewing machine oil or liquid Tri-Flow Synthetic Oil)--probably about every 6 months. Apply a couple of drops of oil every place metal rubs on metal. NO oil on belts, plastic, or cams. Be sure to oil the hook/race (one drop only) every 8 hours of sewing time. She'll probably run forever!
Plate on bottom:
Remove screws. Keep screws in safe place and oil moving parts with good quality sewing machine oil. Zoom with spout for sewing machines & servers is what I use purchased online...lubricate gears with Singer lubricant (in tube). Tip machine back onto a towel to remove screws. Just one drop oil on moving parts & dot of lube gear only if not showing signs of grease already. Please remove bobbin and presser foot before cleaning/oiling. One drop oil then generously SMEAR oil on oscillating hook,
open right front door & one drop top of needle bar.
Clean out race shuttle for lint, fuzz balls, broken threads with soft sewing machine brush & clean your feed dogs gently with bristles too.
Hope this helps. Do not clean machine near children or curious pets! I run my machine with pedal on table top so I don't accidentally step on it. Control with right hand to see moving parts. At your own risk, of course. Safe and effective but only if you are extremely careful. Replace all screws securely. Put in new needle all the way UP into needle bar groove, presser foot UP turning handwheel towards you, flat end of needle to back,
Thread Front to Back of needle.. Keeping presser foot raised @ highest position ensures thread locates the tension slots properly.
Take out the bobbin and then release the hook retainer (black plastic part that the bobbin goes into), but pressing the catch on the inside left-hand-side of the bobbin door. The hook retainer should then drop and the hook can be taken out. Clean around the inside of the hook race (the circular metal part of the chassis that the hook fits in) using a cotton bud and make sure that the small groove that runs around the inside of the hook race is completely clean. Take your oil dropper and put a single drop of oil at the bottom of the hook race - you should see it 'wick' around the groove slightly - this tells you you've put it in the right place. Replace the hook, making sure its properly seated and press the hook retainer back into place firmly until the catch on the left clicks. Rotate the handwheel once to ensure that the oil is distributed and replace the bobbin. You're advised to make sure the needl is returned to the correct position for the automatic threader to work, either by pressing the needle up/down button twice or dabbing the foot controller so a complete revolution is done by the machine. You should oil the hook race every 3-5 bobbins-worth of thread. Hope that helps.
The Activa range is fitted with a light-weight part-plastic hook/shuttle that Bernina claims does not require oiling. However, this does not mean it shouldn't be regularly cleaned and I'd recommend that it is also lightly oiled at the same time. Remove the bobbin case, press the metal lever to the top left of the bobbin door and the black plastic hook/shuttle retainer should pop open so that the hook/shuttle can be removed, or it will just drop out anyway. Use a cotton bud to firmly clean around the inside edge of the hook race (the round piece that the hook/shuttle sits in. Give the whole thing a good clean to make sure any surface grime/fluff is removed. Put a small drop of oil on the running surface of the hook race - the recessed groove around the inside edge, before replacing the hook/shuttle and holding in place by pressing the hook/shuttle retainer back until the securing lever clicks back into place. Rotate the handwheel once to distribute the oil and off you go. Dont overoil but do this regularly and your machine will run much quieter and produce a consistent stitch formation.
Unthread your sewing machine and remove the bobbin. Remove
the throat plate. You may need to remove the presser foot and needle to
do this, and the throat plate may be held in place with a couple of
screws. Every model is different.
the small cleaning brush that came with your sewing machine, or if it's
missing use another similar brush. Brush any fuzz and lint out and away
from the machine. Try not to let it fall back into the sewing machine.
With the throat plate out you should be able to reach most areas of the
machine where lint gets packed. Sometimes if you haven't cleaned this
out for a while it gets packed down until it looks like felt. (There is
no felt near the working parts of your machine. It's lint build-up.
you have removed all the fuzz you can see, take an aerosol can of air
with a tiny tube extender. Insert the tube extender from the some point
at the back of the machine and shoot some air so that any fuzz left
will blow out towards you. Don't shoot the air into the machine, or you
may blow fuzz farther into the machine. Spray in short bursts.
the oiling diagram in your sewing machine users manual. If you do not
have the manual, most older machines require a drop of oil on the hook
(the part that moves around the bobbin) perhaps behind the hook, and
the needle shaft. One drop of oil is all you need at each point, and
then turn the flywheel to move the sewing machine parts and distribute
Many newer sewing machines
have sealed electronics, and the only place you need to oil is the
hook. Refer to your manual or contact a dealer for specific
instructions for electronic models.
the needle and presser foot. Replace the bobbin, and thread the
machine. Using the scrap of cotton fabric, sew back and forth on the
scrap until you are sure there is no excess oil anywhere that could
stain a sewing project. Sew on the scrap until all stitches are clean.
should clean and oil your sewing machine after about eight (8) hours of
sewing time. If you are sewing with fleece, flannel, or doing machine
quilting, you should clean and oil more often since there will be a
faster lint build-up.
Remove the bobbin case.Snap the two retraining arms outwards.Remove the hook race cover and the hook. Oil on right hand side about 4 O'clock... 1-2 drops of oil.Turn the hand wheel until the hook race is in the left position...replace the hook...replace the hook race cover and snap back the two hook retaining arms. Good Luck
To oil machine.....Remove the bobbin case.Snap the two retaining arms outwards.Remove the hook race cover (circular ring ) and the hook ( half semi circular) and clean with a soft cloth.Lubricate right hand side wall ( 1-2 drops of oil) turn hand wheel a few times until the hook race is in the left position...replace hook..replace hook race cover ( smooth end to the bottom) and snap back the two hook retaining arms and insert bobbin case and bobbin.
