It is either the touch pad or the IO board. I state this because IF the pump relay was sticking, it would NOT shut off when you release the parking Brake. The fact that you engage the Parking Brake and the system immediately runs points to those 2 parts. DO NOT CALL HWH. If you E mail them you will get faster response. Are you positive it is the 725 system? There is nothing on an HWH system that ANYTHING with the fluid, would cause the pump to run out of sequence. Either empty, overfull or foaming. Doug
