The relay was definitely bad..... the capacitor was also replaced as this was recommended since it was not 100%. The vibration pump went out earlier and I replaced this. Perhaps there was a short or something and this damaged the board. Not sure as I've replaced the pump before. This is why I was focused on the pump running continuously so I originally thought there might be a blockage, the pump not primed right, etc. Process of elimination let me to the control board must be the problem. Hope that helps. On Sunday, November 13, 2022 at 6:56:27 PM UTC-6 [email protected] wrote:
