I have a Spa with the Brett Aqualine EM 203T Spa Pack. The fliter is on constantly. I tried changing the Timer and I ohmed out the Filter switch and it seems OK. I have to pay $300 for a new circuit board, could it be anything else?

Thanks

the question to ask is, has the filter always ran this way or has this just been a recent problem that jumped up. If it is a recent problem that came up then yes you will probably have to buy the new circuit board. If it is a problem that has always existed then you may just have to reprogram the settings on the circuit board to remove the 24hr filtration, if that is the case then simply let us know what you catalog # is off of the control box and we can tell you how to reprogram it.
