My spa has a Hayward 5KW heater attached and I'm instantly blowing the fuse when I turn the temp. indicator up. I suspect the heater element is bad because I'm only reading 10.3 ohms. Not KOhms.
That seems very low so I suspect a short.
Should add it's 220V.
Any insight would be greatly appreciated. There's not too much to it and my call to Hayward tech support never got answered.
