In Auto Mode my pool runs in Spa Mode only I can run pool filter in Service Mode but I as soon as I put it Auto switches right to Spa Mode. Disconnected the Spa Switch Remote switch to see if it was that but no luck. Assuming it’s the display board, anything else I should check since it’s a $500 part.
