Hallo iedereen, opnieuw beginnen vapen maar probleempje

Hi, i’m new here and have little question about my new vape. I bought a wenax k1 and have a problem with a pod. I refilled it but when i wanted to vape, the red light flickers. I tried it with another pod and it worked. Would my first pod be broken? I only used it for 2 weeks and it worked perfect. (Sorry for my english) greetings
