Brother Disney PE-400D Computerized Sewing Machine - Answered Questions & Fixed issues

It sounds like it has not been correctly threaded or the tension is too tight. Check the tension discs for bits of thread that may have broken off and be causing a blockage.
Re-thread the top threads making sure the pressure foot is up before passing the thread through the tension discs!
Then check the bobbin is running correctly by pulling on the tail of the thread. The bobbin should rotate clockwise. Put the bobbin case in and make sure it is seated correctly.

If all this fails try replacing the needle. A blunt needle can cause all sorts of weird problems

Your best bet is to take it in for service

Time to get it in for service.

serial numbers are specific to each unit.

Two things come to mind. First, if your bobbin and upper thread tension are too tight, they may be pulling the needle out of line. More likely though, is you do not have the correct needle for the weight of fabric you're using. For example, a heavy jean type denim will require a thicker needle than a thin sheet type of cotton. Your sewing store can help you select the correct one.

you can check with brother customer service about the problemand see what they say.

Try sewing instead of the embroidery feature.

If the stitching is messy, the machine needs to go into the shop for service by an authorized Brother dealer as the timing needs to be adjusted. Take a sample of the problem with you.

could you explain more about the threading problem?do you have a manual?

make sure that you don't have any thead hung in the uptake arm also try useing it without the spool cap and see if that works I never use them because of that problem

check the feed dogs under the needle plate to see if there up or down
if there down then the feed dog switch need to be moved to the up position
but if there up,,,then the machine needs to be serviced so the feed dogs & stitches can be checked

im going to help you as much as i can,,,,try using a bobbin that is already threaded and make sure bobbin is in bobbin case correctly, make sure machine is threaded to instructions in book,,,if this is all done exactly u should not have a problem unless something is jammed

That's a tough call, parts can be pretty high to fix a machine. Have looked around to price out a new embroidery machine, Janome makes some very nice one in that price range. I'd try ebay there is one which is missing the foot control and hoops for $250.00 just search Brother Pacesetter PC-8200 this may be the ticket you already have the foot control and hoops.

Best of luck

There will be a lever at the underside...It makes the screen to move while operation... check is it working properly also fix the mechanical part that makes the lever to move...

looping indicates that the tension is not correct best thing to do is get some remnant fabric to hoop up while you work at adjusting your tensions, it sounds like your tension is too loose and sometimes it can take more than one needle change needles like anything can be defective

Check the needle to be sure it is installed with the flat side to the back of the machine.

Try sewing with general purpose thread to see if the machine is stitching as it should. Thread with the presser foot up.

If it is, then re-thread (presser foot up) with the nylon/clear thread. Tighten the tension as you test.

Ok, turn off the machine, take the power cord off. Wait for a few minutes and replug it. Make sure there's no extension plug connected to it.
Then turn it on and check if the buttons work and it doesn't, check if there's any error message or indicator on the screen.

Tension problem bobbin thread coming up even if I reset it down to 2

it cuold be as simple as a blown fuse , unless the board was seriously damaged . AJ

When you pull gently on the thread from the bobbin area, do you feel slight resistance? There should be resistance but it should not be tight. If the bobbin thread is in the bobbin case tension area properly and there is no resistance then you need to tighten the screw on the bobbin case to increase the tension on the thread. Do not tighten the top thread tension. To get to the bobbin tension screw on the case, some models require that you remove the needle plate and then the bobbin case. Some have a hole in the front housing that allows you to reach the screw without taking off the needle plate. Also make sure you're hooping the fabric tightly. When you snap the fabric when it's hooped, it should make a drum like sound. If the fabric is loose in the hoop, bad stitching will result

if the machine is less then 5 years old and you have a proof of purchase it is covered under warr. only the labor is not still covered. It will need a new board to fix the problem
