7 Common Problems With JUKI DX7 (Plus Solutions!)

The JUKI DX7 is a computerized household sewing machine that boasts the company’s formidable industrial  sewing machine technology to create quality stitches and perform just as effectively. The JUKI DX7 has no problem sewing through tough fabrics (which is a miracle for most sewing machines users) and it can turn most sewing designs into a reality. All this coupled with the fact that it is a fairly easy machine to use makes the JUKI DX7 seem like the perfect machine, but upon careful research, this couldn’t be further from the truth. In fact like any other sewing machines, the JUKI DX7 has problems unique to it. And here they are.

1. The Machine Breaks

It’s very annoying to notice one or two parts of a ‘new’ machine out of place or when unboxing the sewing machine and you hear some rattling noises from inside the box. That’s right one of the worst problems of the JUKI DX7 is that it is prone to breaking. Not from a long fall to the ground or by excessive knocking and hitting, but daily or frequent use can see the JUKI DX7 breaking apart. Maybe due to less than stellar build materials.

Luckily the JUKI DX7 is covered under warranty as follows: The mechanical parts of the sewing machine are under a 5 year warranty. Whilst the electronic parts, like the LCD screen and motor are under a 2 year warranty. Plus a 90 day return policy for any defects during the manufacturing, handling and shipping process. The machine should be sent to a specialized JUKI technician if the machine is still under the period of warranty.

2. Bad Customer Service

When you want to enquire about issues regarding the JUKI DX7 from their customer service, it’s either you will not get through or the customer service process will not be completed in that most, if not all, of your problems will not be answered with a solution. This is especially bad because if the customer service of the manufacturer of your sewing machine cannot give clear solutions to problems regarding their sewing machine then who will?

The instruction manual of the JUKI DX7 is one of the most understandable instruction manuals to-date, it would benefit to read through it if you have any problems concerning your sewing machine. There are plenty of online communities with people who have JUKI DX7 sewing machines. Some of which face the same problems as you, others find solutions from experience and careful observation and they nullify the problems. It would be best to find one of these online communities, one in which you are answered by people with the same sewing machine as yourself with probably a little more experience.

3. Sensor (Needle Plate) Is Prone To Damage

Located under the needle plate is a sensor that helps the computerized JUKI DX7 make straight stitches. A problem arises however when the sensor is damaged via the removal of the needle plate whilst the option to sew straight stitches is selected. This problem can also be caused by a damaged spring, also located underneath the needle plate.

When an electronic or technical problem ensues, it is best to find the nearest JUKI dealer or where your machine was purchased and ask them to take a look.

4. Presser Foot Can Malfunction

A false reading on presser foot level causes the presser foot to fall to a point where it is in direct contact with the needle plate. Making it impossible to move fabric through the stitching mechanism (presser foot, needle, feed dog, needle plate, etc).

Fortunately the JUKI DX7 seems to have been designed with this exact problem in mind, offering not one but three solutions to it.

  1. The JUKI DX7 comes with a knee lifter, which is an additional accessory that allows you to manually lift the presser foot. It is shaped like a 7 and works by moving your knee to the right as you push against it whilst connected to a lower part of the sewing machine.
  2. On the top left side of the machine, above the stitching mechanism slightly to the right are three buttons. One has a pair of scissors (it’s yellow) symbol, another has a needle symbol and the last one has a presser foot symbol. Press the one with the presser foot symbol to either lift or lower it to a certain level.
  3. Turning off the sewing machine, waiting for a few seconds and then on again would be a great help. It lets the machine recalibrate and return to its default settings.

5. Presser Foot Detection

When changing the presser foot of a computerized sewing machine, the sewing machine should be able to detect this change and automatically adjust accordingly (needle should be a certain height). The JUKI DX7 does not do this which can be problematic for the needle as it can end up hitting on the needle plate and breaking.

This issue is easily resolved with some manual tuning of course. One of the three buttons on top of the presser foot is of a needle. This button can change the height of the needle in accordance to your liking.

6. Some Measurements Are In Metric

Particularly measurements on the bobbin cover located on the needle plate. This JUKI DX7 problem can spark confusion for most users who are more familiar with the imperial system as opposed to the metric system of measurement. The bobbin cover (needle plate) is in millimeters as opposed to inches. It can be taxing to convert millimeters into inches at the top of your head whilst you are sewing, 1 inch is equal to 25.4 millimeters (it’s worse when decimals are involved).

Contacting the dealer or shop where you bought the sewing machine could prove helpful. Sometimes parts from other JUKI sewing machines are compatible with one another.

7. Knee Lifter Is Unadjustable

That means that the knee lift that comes standard with the JUKI DX7 sewing machine was built with an average body sized user in mind. So for some users with a different body size, the knee lift may be troublesome to use. It could injure the user. This problem is to be greatly considered before purchasing the machine.

The knee lift may be unadjustable but it is certainly removable. It can be replaced with a much more appealing and comfortable (to you) kind of knee lift. Which can be found at the dealer or shop you got your sewing machine from.
