For the series industrial sewing machine, error codes typically flicker on the control box display to signal electrical or mechanical issues. If your machine uses a common integrated servo motor system, you can use the following list to troubleshoot and get back to work.

| Symptom / Error | Probable cause(s) | Immediate checks | Fix / next steps | |---|---:|---|---| | Machine won’t power on | Faulty power, blown fuse, switch, controller issue | Confirm mains power, check power cord, fuse, on/off switch | Replace fuse or cord; test outlet; if power present but no boot, inspect control board or call tech | | Motor hums but no movement | Drive belt slipped/broken, motor coupling, clutch issue | Visual belt inspection, try manual handwheel | Replace/adjust belt, tighten coupling, check motor brushes | | Excessive vibration / noise | Loose screws, worn bearings, timing issue | Check screws, oil points, listen to bearings | Tighten, lubricate, replace bearings, service timing gears | | Stitch skipping / uneven stitches | Needle bent/worn, incorrect needle size/type, timing off | Replace needle, verify needle is correct and installed fully | Fit correct needle, re-time machine, check thread path | | Thread breakage (upper) | Tension too tight, poor threading, burr on needle plate or hook | Re-thread, clean tension discs, inspect needle/plate | Reduce tension, replace damaged parts, clean lint | | Bobbin thread breakage / birdnesting | Incorrect bobbin winding/placement, hook timing, lint | Re-wind bobbin, clean bobbin case, check insertion | Rewind/insert correct, adjust hook timing, clean surrounding area | | Inconsistent stitch length | Feed dog height, presser foot pressure, timing | Check feed dog movement, verify presser foot pressure | Adjust feed dog/presser, service timing system | | Fabric not advancing | Feed dog down, presser foot, clutch/drive problem | Ensure feed dog raised, presser foot down | Raise feed dog, repair drive linkage | | Overheating / motor trips breaker | Motor overload, binding mechanism, electrical short | Remove load, run machine empty, smell for burning | Clean lubrication points, inspect motor wiring, replace motor if needed | | Error code on panel (e.g., E1, E2) | Electronic controller faults, sensor failure, encoder/communication error | Note exact code, power-cycle machine, check connectors | Consult manual for code; reseat connectors; replace sensor or controller as directed | | Servo motor alarm / “ALM” | Encoder mismatch, wiring, overcurrent | Check encoder cable, motor connectors | Replace or repair encoder or motor driver | | Tension dial not responding | Broken tension assembly, internal linkage failed | Try different dial settings, inspect assembly | Replace tension assembly or linkage parts | | Oil leakage | Overfilled oil reservoir, damaged seals | Inspect oil level, locate leak | Replace seals, refill correct oil amount | | Machine stalls intermittently | Intermittent electrical contact, worn clutch, loose wiring | Wiggle wiring, check connectors, observe when stall occurs | Repair wiring, replace clutch/solenoid | If your machine uses a common integrated servo

(If your unit shows other codes, treat them as controller-specified — power-cycle first, then consult manual.)

Check for thread jams in the bobbin area or "bird's nests" that might be locking the motor.

Check the cable between the display and control box for loose connections. Pedal Signal Error
