OK, couple weeks ago my 3 year old generic spa with a balboa control got a OH error. I removed the filter and the problem went away. I replaced the filter last week and today it did it again. I removed the filter and found a bunch of stuff from the tree next door, kids must have left the cover off. I sprayed out the filter and replaced. The OH finally went away but now the control is blinking and counting by 2's from 80 degrees to 104 degrees constantly, up and down. I've tried powering off shortly but that did nothing. I'd appreciate any help with this spa
