Hello there, i currently run out into a problem with my valve basestation from last year. While working this one make an insanely loud buzzing noise (like something was block under the rotor or something close to it). I try reaching valve concerning the problem but they told me my warranty was already over. As right now, i'm looking for a place where i could get it fix or even just try to fix it myself but i don't know which tool would be the best to open the curve glass from the basestation. If anyone could give me recommendations it would be greatly appreciate.
