Dishwasher Door Latch Tripping the Machine? NL-DLK-4 Dishwasher Door Switch Endurance Tester Runs Four Stations (dishwasher test equipment)

The dishwasher door latch and door switch carry the safety interlock: power only when the door is closed, stop the moment it opens. Insufficient bolt travel, degraded contacts or short mechanical life cause constant error codes and mid-cycle stops — and in the worst case an energised door that can be opened. Door switch life and interlock reliability must be verified with a quantifiable cycling test before shipment.

What the NL-DLK-4 door switch endurance tester measures

• Four stations closing and opening in parallel, reproducing real closing force and travel
• Latch-in-position signal and interlock contact make / break reliability
• Contact resistance trend over the full action count
• Closing force – displacement curve with automatic jam detection
• Action counting, automatic failure stop and record
• Optional live load switching to verify the safety interlock circuit

Applicable standards

IEC 60335-2-5 (dishwashers – safety), GB 4706.25 (particular requirements for dishwashers), IEC 60436 (dishwashers – performance), GB/T 20290, IEC 60730-2-8 (automatic electrical controls).

Stations and throughput

Four-station and eight-station configurations running 24/7 — the hundreds of thousands of door cycles no operator can complete by hand are finished in a few days.
