I replaced the heater relay a week ago and the spa heated up for a day, then failed. If I disconnect the power for a bit and reconnect, it resets the heater relay board and works for a day or so, then fails again. Lather, rinse, repeat. I was told the new heater relay may be faulty, and/ or the new relays are not compatible with the old motherboard, so it's time for a new motherboard.
Naturally, I'd like to fix this, but want to make sure I'm solving the real problem, and not just throwing money at it. Thanks.
