Question about Bernina Virtuosa 150

Bernina Virtuosa 150 Presser Foot Loose

The presser foot feels loose when in the down position and the fabric doesn't feed. If I push down lightly on the foot the feed dogs engage and the fabric feeds. The presser foot isn't applying any pressure when in the down position.

Hi I have a 15 year old Frister Rossmann serger which I got second hand 10 years ago. It has had one break down which was my fault for not getting it serviced for 8 years. Not sure where in world you are. They sell as Frister Rossmann in UK and Europe and Kenmore in the US. I've used it mainly for dressmaking and soft furnishing projects. One more thought on the Bernina have you tried leaving a query / searching on the US Bernina website www.berninausa.com I use them alot. Try and stick with getting the Bernina sorted, I love mine!

SOURCE: Feed dogs don't want to feed.

Sounds like the feed dog height is not set correctly. You could fix it yourself but you would need a dealers service manual and there is a height gauge that should be used although I have set them by eye...and experience.
Bernina's are fantastic machines and I have yet to find even one that is a lemon. Just like finding a good auto mechanic, you need to find someone that actually knows more than how to blow off lint and apply oil.
Your problem should be a low cost quick fix/adjustment that can be accomplished by a knowledgeable and skilled technician.
Good luck finding one!! Bill

SOURCE: tension on my artista 200 bernina machine

Please TRY the solution BEFORE giving your considered rating.
Specific detail on bobbin case adjustment (with picture) near halfway down reply, the remainder will help you achieve a balance of top and bottom tensions.

Ensure that all is clean and free of lint and jams, this is the most likely cause....now for tension troubleshooting .......

This solution is for tension problems...if you cannot form any sort of stitch, the issue is quite different, so please let me know if you need a different problem solved.....

It is quite long, but just work through each section in order.

The "knotting up" can reveal a lot. If you have loose threads on one side or the other, the tension on the opposite side will be the culprit.

QUICK SUMMARY FIRST:
Ensure sharp new needle,
Thread guides and Bobbin are Clean & Clear of lint
Set Top Tesion to 4 ....then....
Balance Bobbin to suit.

TOP THREAD TENSION:
If the looping threads are on the underside as you sew, it is the top tension. Top tension ought to be between 4 & 6 (this variation to allow for the different weights of fabric in your projects).

IS YOUR NEEDLE SHARP ?
If you are using a needle that has seen quite a deal of work, or you suspect it may be blunt, change it for a new one !

TOP TENSION & GUIDES:
Make sure that when you thread the machine the presser foot is up so the thread goes between the discs and not to one side, top tension between 4 and 6, and that you have threaded through all the guides, including the last one, usually on the needle arm, just above the needle clamp.

It may be there is lint trapped between the discs, this will keep them slightly apart and reduce the actual tension, sometimes dramatically.

If tensions appear correct, and the thread is definitely in the channel between the discs, but still too loose and looping, try raising presser foot and remove your thread.

Now, with a 2" (50mm) wide strip piece of fabric 8 - 10" (20 - 25cm) moistened with methylated or denatured spirit, gently insert the fabric strip and clean between the discs with a see saw / to and fro action.

In the worst cases, gentle use of a needle to pick & remove the jam may be necessary, but be very gentle and make sure the tension is set at Zero and the presser foot is raised, (to disengage tension plates).... do not gouge or score the plates, they need a polished surface to work correctly.

BOBBIN TENSION:
Far less common, but if the loose threads are on the top, it is bobbin tension that is loose, it too may have lint in the spring and be giving a "false" tension.

I would not recommend fiddling with bobbin tension without good reason, it may end up with missing small screws and spring pieces, however, you can take the needle plate off to clean
the hook race area (where bobbin case sits)

...this is just good housekeeping, my wife does this every time she replaces the bobbin....

just take it out and clean the bobbin case and the fixed metal hook race with a small brush to remove lint. If there is a significant amount of lint, use a vacuum and small brush to get the worst.

Then wipe all this area with a cloth or cotton bud (Q tip) moistened (not soaked) with methylated spirit, especially if there appears to be fine dirty deposits....oil and lint combine to conspire against you.

If it seems likely that you ......really ....do .....actually .....need .....to adjust the bobbin case, first check there is no lint trapped in the metal spring where the thread is tensioned.

TOP LOADER:
Drop-in Bobbin case will look similar to this image with the tension screw in the middle of the metalwork....

4c76dc1.jpg ...the other screw at one end is holding it all together, so beware....it is not a tragedy to undo the whole lot and clean it, but very gingerly and lay the bits out in sequence and orientation, or you risk tearing your hair out !

FRONT LOADER:
....this is a bobbin case from a front loading machine and works in a very similar fashion to the top loader with drop in bobbin, again, if you dismantle it, take care so you can put it all
back properly.
165ca5c.jpg FINISHING UP
GETTING THE BALANCE RIGHT:
When you are certain there's no trapped lint in top tension or bobbin, set the top tension to 4 and the bobbin tension to a point where you just begin to feel resistance.

Try using good quality thread of contrasting colours so you can more easily spot the changes.

Set your zigzag to one width less than maximum (eg. 5 of 6 ...or... 4 of 5 etc) and sew a sample for a few inches and check the result.... adjust the bobbin tension screw very little at
a time, perhaps 1/16 of a turn.

You may find you are playing with this balance for some little while and if you are putting the needleplate on and off each time begin to think it cannot be correct to do this.....BUT....it is,
and eventually, you do get a "feel" for the correct tension and then it happens quite quickly.....as a user you won't be doing it very often unless there is lint built up (or are there small hands at work around the house !?!?!)

OTHER ISSUES:
If you live near the ocean as we do, salt air can play havoc with metalwork inside and out, so to help minimise this, keep a few small packets of dessicant (silica gel) in your machine
case....no case ? then make some sort of cover !

Same applies in any damp or humid environment, keep your machine dry and dust free.

Budget for a proper full service every couple of years (more often if heavily used) and if you don't use your machine for a few years, be aware that old oil will dry out and combining with
dust and form a "clag" like glue (another reason for some sort of cover, even a teatowel !)

FINALLY, A WORD ON THREAD:
If it is worth spending the time, energy and money on making something that you would like to give lasting enjoyment......use quality thread, .......it may seem to cost a little more at the
time, but the results, ease of use and added longevity will be worth the extra, and as a bonus, your tension troubles may be fewer and further between, because there is a more consistent diameter with good thread, and less compensating to be done by your tension plates and less thread breaks

Hi, My Elna 7000 doesn't easily feed medium or thin fabrics. Presser Foot tension lever is position 2 and the Feed Dog is rising normally. Any thoughts please? Does the F Dog wear out in any way?


Generally, the lighter the fabric weight, the heavier the presser foot pressure. Yes, feed dogs do wear with use. Do not run the machine without fabric between the presser foot and the feed dogs--the feed dogs constantly rubbing against the presser foot will quickly wear the feed dog points. Store the machine with the presser foot down with a pad between the presser foot and feed dogs (even a scrap piece of fabric will do). Also, be sure to clean the feed dogs of any gunky build-up. If the feed dog points are worn, it may be worthwhile to have them replaced.

HV sapphire 930 not feeding properly


When stitching together a quilt sandwich, it is recommended to use a walking foot on your machine. The walking foot moves the upper fabric in conjunction with the feed dogs. Sometimes, if the quilt sandwich is not too thick, a roller foot can also help but may not be sufficient for a quilt sandwich.
What is Walking Foot Sewing Tips for Beginners
How To Use Walking Foot
How to Use Roller Foot

You may also check the presser foot pressure on your machine. This regulates the amount of pressure the presser foot applies to the fabric and the feed dogs. If the pressure is too strong, it will tend to push the upper layers of fabric, creating a bubble look. If the pressure is too loose, there is not enough pressure for the feed dogs to physically pull entire quilt sandwich under the presser foot.
(The pressure is adjustable depending on the types of fabric and thicknesses being sewn.)

The presser foot doesn't sit all the way down in order to sew correctly. Can I adjust it myself? How?


Has that particular presser foot worked in the past? Do the other presser feet work?

If it hasn't been used before, check that it is the correct foot for the machine. Is it perhaps a darning foot or free motion foot? If so, those particular feet are made to Not rest on the feed dogs so that the fabric can be manually moved without the use of the feed dogs.

If none of the presser feet work with the machine, then the needlebar has probably shifted. It may be best to take it for service as it may require specific tools and gauges to adjust it properly.

No knob to adjust presser foot pressure. Space between feed dogs & presser foot is too tight to pull a piece of fabric out with foot down. Diagonal seams get pushed out.


You should not be able to pull fabric from the machine when the presser foot is down. The presser foot should always be raised before removing the fabric.

Are you trying to darn or quilt something without the feed dogs activated? If so, there are special presser feet for that purpose that are shorter in height (ie darning foot) which allow more space between the presser foot and the stitch plate so the fabric can be moved freely.

My BV 160 is giving me problems. The fabric will not move along as I sew. I hve ck'd the feed dogs, they're ok, rethreaded the needle, bobbin, cleaned the bobbin but still not sewing.


have you checked the presser foot to see if the presser foot is holding
the fabric against the feed dogs so they can move the fabric thru to
be sewn by the needle?

The bobbin thread keeps bunching up - I have cleaned it and changed needles - what else do I do?


When you are threading the machine make sure that the presser foot is up, The tension disks are open when the presser foot is up, If you thread the machine when the presser foot is down the tension disks are closed, and the thread will not go through properly causing a nest of thread of bobbin thread to bunch.

Feed dog


It may need the feeddogs adjusted by a tech. We use a guage to measure the correct height. Even though visually it may look like they are moving ok they may be too low. You could use the top end of a needle and lay it alongside the feeddog at its highest point. It should be level. Also check the presser foot pressure. It may be set too high and not holding the fabric down. Good luck to you. Rick
