Question,

i have a hayward pl-plus automation system. I recently replaced the circuit board because the clock stopped working. The clock now works fine.

Everything appears to be working except the timer for the filter. The timer is set to run the pool for 6 hours. The timer properly turns on the filter. However, the timer fails to turn off the filter at the scheduled time. I have to manually shut of the filter via the control board.  Any ideas?? Thanks.
