This new genuine original Smeg door interlock switch is currently in stock under part number 696293489. Also known as a door interlock, it helps secure the door and confirm closed-door operation. If you need to double-check fit, use Fixit Fox Finder or contact customer services before ordering.
Quick delivery and also one of the few suppliers in the UK to have this part. It was compatible with our SMEG DI613PNH dishwasher (albeit there was no programming socket on the motherboard like there was on the original). The original board was definitely faulty with no display LED's but it did beep when buttons were pressed. The new board got both the main LED display working and the program mode LED's but there was still a fault as the display showed 888 and none of the buttons did anything apart from beep. I think the fault was more subtle probably being the wiring, not the CPU board. Will definitely use Spares2Repair again!
