Hi

So ad blue pick up filter all good. Filled new ad blue air filter with boiling water and after 15 mins of running I’m getting an occasional mist. Not sure what I should be getting.

You should be getting the hot water out ,flush it 3 times or as many times as you want ,but it it doesn’t clear the pump requires replacing
