First of all, I feel like I'm flooding this excellent forum with all kinds of rookie topics, but I am very greatful for your input, so please bear with me . Now here's something that puzzles me. After washing my car with a pressure washer , 3 out of 4 times nothing happens when I turn the key. Apart from the electrics going on there is not a click when I turn the key. And strangely enough it always starts on the 3rd attempt. And then it's fine . Until I wash it again. 🤔

What's going on??
