Viking Sapphire 835 help please
A friend has this machine. Yesterday she said after sewing a few minutes she ended up with quite the birds nest of bobbin thread. She rewound bobbin; rethreaded upper and lower thread a couple of times and still having same issue. Told her it sounded like there might be a tiny piece of thread stuck somewhere and maybe could use a good general cleaning. Told her to use vacuum and not canned air in the bobbin area. Being the good little do bee that she is, she read the manual and it said to drop the feed dogs when cleaning. She did this, cleaned out all the lint, etc. and now the feed dogs will not come back up! I went to see if I could figure out anything to no avail. Checked to make sure the FMQ settings had not been changed (and they were not plus no pop up menu to that effect); turned the machine on/off several times; took apart bobbin area several times. Don't know what else to do. Any hints or clues? Any help would be greatly appreciated. Off to look online some more now. TIA
