Janome MC10000 Warning & Machine Won’t Sew

MC10000 WarningIf you have a Janome Memory Craft 10000, and as soon as you try to sew it gives you an error message, then you’ll need to bring your machine in to your local Janome dealer for a repair.

This warning does not point to a single repair issue, but there are some common things that your dealer’s technician can do.

The error is clear:

! Warning
Is something stuck in the machine?
Is cloth too thick?
Is needle bent?
Check the above and restart.

In all the years that I’ve worked on Janome machines, I’ve had this issue with the MC10000 twice. In fact, it had been so long since I’d seen this issue that I had to call Janome and ask for help to know what to check.

How to fix the machine:

First, I cleaned the machine and checked for binds. Since the warning message clearly indicates that the machine thinks it is jammed or bound up, it’s important to make sure the machine is rotating freely.

Next, Janome told me to look for loose or disconnected wires. There were none. Janome indicated that the problem was almost certainly the main motor. I happened to have a main motor in stock, so I decided to try that. When I installed the new motor and then plugged in the machine, the new motor worked!

There are some other things that could cause the warning to appear, such as a bad stepping motor or circuit board, but that would be extremely rare. If you have a Janome MC10000 with this warning, don’t worry about it, just bring it in for repair.
