By string, I assume you meant thread ? Is it bunching up underneath the fabric you are sewing, or on top ?

If it bunches up underneath the fabric, the upper thread tension may not be right or the mechanism may be worn or need replacing. If it bunches up on top, thread guides may be catching or the needle may be damaged.

First thing, try a new needle. Damaged or dull needles can cause problems. Also try a new spool of thread, because sometimes a thread spool might have been damaged or is just bad quality. Some machines will not work well with very cheap, economy threads, so if you're using cheap thread, get better thread to try also.

Test stitch after each change you make to see if it's helped. The upper thread tension adjustment should work at any setting, but for normal sewing, should be at a middle setting.

If thread snarls up on top of the fabric, unthread the machine and check every thread guide for wear or nicks that might be catching thread.. needles can cause this also. May need to replace a guide if it's damaged, or perhaps use a file, emery cloth or sandpaper to smooth a rough spot. Rethread the machine with a new spool, set the upper tension to a medium level and try again.

If the thread bunches under the fabric, it's often the upper tension that's not right. Thorough cleaning of lint from the bobbin area should be done also, even a tiny bit of lint can be a problem in some machines. Try rethreading, try a new spool of thread, and a new needle.

If no setting on the upper tension produces a balanced, even stitch without bunching, the mechanism of the tension adjuster may be worn and need either professional adjustment or replacement.

Very rarely, you may find the bobbin tension might also need adjusting. Take out the bobbin case, you'll see the tension is controlled by a small spring which has a tiny slot screw on it. Mark the exact orientation of the screw slot now, [ marker pen or tape] so you can put it back where it was if need be. If you have to to a adjust it, you should move that screw only a tiny fraction of a turn at a time.

Check bobbin tension - pull out a foot of thread and hold the end of it , with the bobbin case dangling. Shake the case up/down like a child's toy YO YO. If the bobbin moves along in reasonably even increments with each jerk, it's likely ok. Or you can pull it along and see how hard it is to pull. If the bobbin case won't move or is hard to slide, it is too tight. If it slides on the thread freely it is too loose.

Usually. clockwise turns tightens the tension, but check to be sure. One tiny adjustment at a time, it gets a bit tedious. You have to put the bobbin back in and try a few stitches after each adjustment to see if the bunching is getting any better. If it makes no change or makes it worse, put the screw back to the original position.

If you are handy and can find a repair manual for the machine, you may be able to adjust the upper tension mechanism yourself, it should not need special tools. Often for older machines the hardest part is finding another part to replace the damaged one.

How can I clean the upper thread sensor? My machine continually throws a "Check upper thread" error, even though the upper thread is fine. It seems the sensor is not "Seeing" it.

Try using waxed dental floss to dislodge the snag. Gently pull the floss toward the needle through the thread path. You might have to do it several times. You can use canned air to blow the lint out of the machine. Then make sure you are using a good quality thread. Avoid those cheap spools of thread because they usually are not spun tightly enough to prevent lint build up in the thread path.

My in-ground pool pump...Sta-rite 11/2 hp...leaks at the outlet fitting. Changed fitting twice, using teflon tape as recommended...still leaks.

I don't recommend Teflon tape as it places outward pressure on the pump and can cause the pump body to crack. and if that happens the pump body will need to be replaced. I use black RTV silicone. smooshing it into the threads of both fittings and hand tightening the fitting.. then the glue the pipe as normal
REMEMBER to prime the pump after any pump repair !!
Teflon tape works well on metal pump like well and irrigation, they are a high pressure pump and are generally cast iron tanks.

Can I use thread tape on radator fittings and power steering pumps?

Highly not recommended. The pressure that builds up in these systems is more than thread tape can withstand. Use the right type of clips. Cheap approaches >> big trouble

The screw threads might, possibly, have been stripped. If so, wrap some plumbers Teflon tape around the screw threads. That should help sock the screw in snugly. The tape is dirt cheap and goes a long, long way.

Won't except tape

I have a ZR100 that did the same nearly the same thing - but it was only beeping twice. I followed the advice another thread suggested - I banged it twice on the opposite side from the door but it didn't fix it. Then I banged it twice on the side with the tape door.... and now all is well!

I couldn't believe that "fixed" it. Like banging the ol' tube color TV on the side to fix the picture. Maybe it is short lived, but if it holds for the rest of this year until the camcorder Christmas sales begin, I'll be happy!
