Hello Everyone, I've owned an arctic spa since October and have had no issues till today. The spa was ordered with Bluetooth and wifi but the wifi was not installed till last week. Wifi worked great but I noticed that the software version was 1.04 and before the wifi install I was running 1.32. Downloaded the latest version 1.32.1 to the spa with no issues. Now for the problem. Whenever pump 2 is activated I get feedback to the speakers. Loud humming sound. I can stop the interference by activating pump 1 or 3, but every time pump 2 is activated the humming starts again. Any ideas why or where this feedback comes from would be greatly appreciated. Thank you, Reinhold
