Code 88 is a threading issue.
First you need to make sure that you are using the original bobbins that came with your machine, your machine uses a plastic class 15J bobbin, if you want to purchase more the part number is 085128. If you have purchased additional bobbins, make sure they are the correct ones. Do NOT use pre-wound bobbins or metal bobbins; they will cause tension problems. Using the incorrect bobbin can cause the timing to be disrupted on your machine. If this is the case, the machine will need to be serviced.
The quality of the thread you use will also impact the quality of your stitching, more often than not; tension problems are often caused by poor or old dried out thread. We recommend using Coats and Clark or Gutterman thread.
Use only Singer brand needles, category 2020 for wovens and category 2045 for knits and synthetics. Using other brands such as Schmetz will cause tension problems. Using another brand of needle can also cause the timing to be disrupted.
The problem you are having may also be an indication that the upper tension disks of your machine are not threaded correctly. Here is an easy test you can perform to help you determine if your machine is threaded correctly. First raise the presser foot (UP POSITION) by turning the hand wheel TOWARDS you, never turn it away from you, you can knock the timing out when you do this. Now go ahead and thread the machine all the way to the last guide before the needle (DO NOT THREAD THE NEEDLE). (When threading this area of the machine, it helps if you hold the thread securely with your right hand just after you slip the spool of thread and spool cap on to the spool pin. Continue holding the thread until you arrive at the last thread guide before the needle). Next with the presser foot UP pull the thread towards you, there should be very little resistance. Now LOWER the presser foot, if the tension disks are threaded correctly, there should be a significant difference in the tension when you pull the thread. There should be resistance. If there was very little difference with the foot down versus the foot up, you need to repeat the threading steps. If there is a significant resistance, proceed to threading the needle. You are now ready to sew. You will find more threading information by visiting our website at www.singerco.com, and clicking on "Sewing Resources” on the toolbar and then select “Operation Basics".
If the problem persists, please take your machine in for service to your local Singer retailer. To find a retailer go to www.singerco.com, click on “Where to Buy” and then enter your zip code. If your machine is still covered by the warranty (parts and labor are covered for 1-year from date of purchase), please take or ship it to one of the warranty centers on the list we have attached. Be sure to include a copy of your receipt, the warranty center needs this to complete warranty work.
