What does the warranty cover?

For specifics, refer to the warranty information provided at time of purchase. In general terms, a warranty normally covers defects in materials or workmanship by the manufacturer and seldom, if ever, includes labor, normal wear items, or improper use.

Do you give estimates?

Counter estimates are provided at no charge when the machine is brought in to the store.

What does a basic service cost?

The cost for a basic service is dependent on the type and model of the machine, starting at $90.

Does basic service include bringing my machine software/firmware up to date?

When the updates are available to us and the update does not require chip or board replacement, the answer is yes.

How often should I have my machine serviced?

Frequency of service is really dependent on time and usage. As a rule of thumb, if a machine has been sitting for 3 years it should be serviced before it is used. If you are a “closet sewer”— one who only brings out the machine for that occasional repair or set of curtains — every 3 years is probably still adequate. If you’re a more avid sewer, say sewing on a weekly basis, annual service is probably more in line.

What do I need to bring in when having my machine serviced or repaired?

When bringing a sewing machine in for service please bring the machine, cord(s), foot or knee control, zigzag foot, needle plate, sewing bobbin case, bobbin, and warranty card.

Do you sell just the parts?

Yes, when available. If the needed part is not in stock we will special order it for you.

Troubleshooting:

I’m having tension problems; the thread is bunching/bird-nesting/looping on the bottom. What’s wrong?

This is probably the most commonly asked question and, while there are many things that can cause it, the following is the recommended course of action:

  • Re-thread the machine, with the presser foot up. Improper threading, resulting in lack of upper tension, is the most common cause of looping on the bottom.
  • Prior to threading the needle, lower the presser bar and pull on the thread. You should feel notable resistance.
  • Clean debris from the hook and race.
  • Put a drop of hook oil on the race, this should be done about every 3-bobbin loads of thread or when starting a project if the machine has been sitting for an extended period of time.
  • Clean out the inside of the bobbin case and re-thread the bobbin.
  • If the above does not solve the problem, it’s time to bring the machine in for service and repair.

My machine is skipping stitches.

As with looping, there are a number of issues than can cause this problem. Prior to bringing the machine in for repair try the following:

  • Replace the needle, being sure that the flat part of the needle (in most cases) is facing the rear of the machine and the groove running down the length of the needle is facing you.
  • Follow steps above, under tension problems.
