3 year old Hayward Super II pool pump went out after intermittently turning itself off due to overheating for a month. Pool vacuum booster pump and spa aerator still worked fine. I replaced the Hayward Super II with a Xtreme Power 75035 pool pump from Home Depot trying to save a few $$ because the Hayward pricing has gone nuts. The Xtreme Power 75035 is a dual speed pump which I intended to set to run continuously on the high speed when activated by the timer. Pool pump and booster vacuum pump uses a Intermac T1040R dual timer. The spa aerator wires run through the Intermac timers on the feed side, but the aerator has it's own off and on switch built onto the unit itself. I bought this house in March of 2015 and replaced the existing Hayward Super II with another Hayward Super II in the summer of 2016 without any problems.
Now neither the new pump, booster pump, or spa aerator come on. Even the timers don't appear to be keeping the time either? They all act as if they are not getting proper voltage, but I tested the circuit and the two hot legs have 120v each at the timers, pool pump, and vacuum booster pump. All appear to have 240v power when checked. The power lines to the pool pump and vacuum booster pump are dead when the timer switches are off and live when the are switched on manually as they should be. I even wired the system hot by attaching the pump power lines on the timer at the same location as the feed from the breaker box to bypass the Intermac timer switches and still the same problem?
I am out of ideas.....
Wiring explanation:
Incoming from breaker box is on the right side to the back. the extra white and blue wires are not used.
Power to the pool pump is the right front
Power to the vacuum booster pump is just to the left of the ground bar
Power to the spa aerator is in the front to the far left
Power to a pool light switch down the wall is to the back on the far left. These wires are not connected to the timers. They go directly from the breaker box to the pool light switch.
