The bobbin on the Janome Sewing Machines is one of the most common problems identified. The bobbins jam, the bobbin thread tangles, and the bobbins fail to reload properly making it difficult to use the machines consistently, according to customer reviewers on Amazon.com.
Other common problems with the Janome sewing machines include breaking needles, malfunctioning needle threaders, and failure of the feed dogs. The company does provide a troubleshooting manual on its website to help address issues that arise when operating the machines.
Three complaints against the Janome company with the Better Business Bureau have been closed within the last 12 months, as of March 2015. The company does not have BBB accreditation.
