Bernina virtuosa 155

Hi ive been having some problems with my machine, it has started sounding like its chugging and the bobbin sounds like its rattling a bit. i had this problem before and opened up the top and tightened some kind of arm holding the tension and oiled the bobbin area. it seemed to work again and hardly made a sound. but i have had to oil it several times each time i use it for that noise to go away and the stitches be even but now it is happening again, the stitches bunch up underneath and it sounds really bad! i live on a remote island and nobody here has heard of bernina i dont think so i have to do all repairs myself!please help!

Firstly, dont flood it with oil - it will end up making a mess for you!
What I'm going to tell you is basic, but work thru it.
1. take out the bobbin case and swing the two latcjes to the side so you can remove the hook. Inspect the point VERY closely. should be sharp and absolutely smooth. ANY burr or nick MUST be removed. (have you broken a needle recently??)
2. Lay the mahine on its back, refit the hook and lock into place. Put in a BRAND NEW needle With the bobbin case still removed and the machine turned ON and in MAXIMUM Zig Zag width, turn the hand wheel in the direction it normally rotates - towards you. When the needle swings to the Left and is on its wasy UP, the hook point must pass behind the needle a little before the eye of the needle reaches the arc that the hook point travels thru. Same on the Right swing. If it does, GOOD.
3. Wind an empty bobbin with GOOD QUALITY THREAD. It should wind on reasonably even and TIGHT. When you push your fingernail into the thread it must NOT be spungy. Insert bobbin into bobbin case (IN THE CORRECT DIRECTION). Hold the tail of the thread and allow bobbin case to dangle, it should not drop down until you give the thread a little jerk. It should drop a little then stop. Insert bobbin case into machine, thread top of machine CORRECTLY. Set top tention to normal, test sew.
Let me know how this goes.

Make sure you are turning the flywheel the correct direction.

Hi - hope someone can help me. I have a Bernina 121 and no manual. It seems that the bobbin winder is on - and I can't figure out how to switch it off so the needle will go on.

Do you use the flywheel to disengage the clutch and wind the bobbin?

Alternatively, newer machines have a bobbin winder on top and usually you just flick the winder over to engage, then back to disengage. There may be a button on the front that drives the winder motor during this process.

You may find some ongoing help if you join the Yahoo Bernina virtuosa user group, I find user groups are a great resouce and you learn lots from fellow owner/users of your machine.

Good luck.

I have a Bernina 153 QE Virtuosa. The bobbin carriage is noisy. When I notice that it is suddenly sounding smoother, I can be sure it has run out of bobbin thread. I have taken it in to my dealer for...

The previous answer is incorrect. The bobbin should turn clockwise in the bobbin case, but then the thread doubles back through the bobbin case tension slot so the end of the thread would be pulling counter clockwise. Are you using genuine Bernina bobbins? Sometimes, generic bobbins do not work as well.

Are you applying a drop of oil to the shuttle/hook area every 8 hours of sewing time? Lack of oil makes my machine noisier. When I notice the sound has changed, I know it's time it needs some TLC.

If you are still having problems with the Bernina technician, try to find another dealer.

I have a Bernina Virtuosa 155 and use it daily. Without

In checking I can either adjust the tenion screw and if that does not work, purchase a new bobbin case.

Machine not working after bobbin installation

Hi, it may be possible that you put the bobbin in the case upside down and its turning the wrong way. Flip it over and try it. When looking at the bobbin in the case from the back and you pull the thread, it should turn clockwise.
Hope this helped as anything else may take a tech to diagnose.

Sewing Machine Singer 4423 timing problem Hi, I got a brand new singer sewing machine 4423 from ebay, it was cheap and bran new on the box... I tried to stitch and it didn't work, I contacted the seller and he told me I need to return it, but returning it means paying 50 euros for shipping. I explained to him that it is not my fault the machine doesn't work and I shouldn't be charged to return a faulty one but he didn't care. He is from USA, I am from Greece, I cannot go to his house and punch him... so I fixed the timing myself, it is easy. BUT the timing gets wrong again within some time of sewing, I have to repeat the whole process or fixing the timing again. I am putting the screws tight, I am scared they will get even more ruined if I keep opening it all the time. I know how to time it correctly, I am fixing it and then after some time, it still loses its timing by itself. I double check that the screws of the gear are tight and they don't "slip" or anything. Effectively it is like I have no machine, I cannot just "hope it will work", a sewing machine of this type is supposed to be like a contract, if it starts failing I need to fix the timing which takes time and it needs to open the case. If I go really slow it might last longer, but I got this machine because it is supposed to be heavy duty with 1100 stitches per minute so I am wasting my time. I am kinda cursed with things like this, usually things never work for my favor and right now I got a machine from an a**hole and although I can fix the timing it gets back to wrong timing again on itself................................. SO does anyone know what could be causing this problem? If the screws are pretty tight, what could cause this thing?
