The 27-Point Testing Checklist We Run on Every Used Washing Machine
"Tested" is the most abused word in the used-appliance trade. Here is what it means at our benches, checkpoint by checkpoint, so you can demand the same standard from anyone you buy from, including us.
Intake (5 checks)
1. Age verification from nameplate/model code. 2. Visual damage survey (panels, frame, base). 3. Door/lid alignment and seal condition. 4. Cord, plug and earth continuity. 5. Model history screen, recalled or problematic models pulled from sale lines.
Function bench (14 checks)
6. Power-on and control panel response. 7. Inlet valve fill test. 8. Water level sensor accuracy. 9. Wash agitate motion (both directions). 10. Drain pump full evacuation. 11. Spin cycle engagement. 12. Spin balance and vibration measurement. 13. Motor load current draw vs rated spec. 14. Belt tension and wear. 15. Bearing noise under spin load. 16. Lid/door safety cut-out. 17. Drain/leak inspection under full cycle. 18. Detergent drawer and filter condition. 19. Final cycle completion without fault codes.
Presentation (8 checks)
20. Deep clean interior tub and exterior. 21. Detergent drawer deep clean. 22. Filter cleaned and reseated. 23. Cosmetic grading against photo rubric (A/B/C). 24. Grade tag fixed with serial. 25. Accessories verified (hoses, caps). 26. Data entry: serial, grade, test results into the batch log. 27. Photographs for the batch evidence pack.
Why the log matters more than the testing
Anyone can claim 27 checkpoints; the proof is the spreadsheet. Your batch QC log maps serial numbers to results, so a unit that fails at your shop in week two can be traced to its bench record, and our warranty process starts from that document, not from a debate.
Ask for a redacted sample log on WhatsApp. Reading one teaches you more about this trade than ten supplier conversations.
