    Is this a new motor just installed or an old unit?

Sounds like the thermal protector for the motor is tripping. This means there is a problem with the motor overheating.
It is a self resetting switch so when it cools off enough the pump will come back on. It also means you probably need a new pump.

SOURCE: my pump pressure is 10psi i cleaned the de filters they seem fine i have good floe out of my jets but when i hook the pool cleaner up pressure drops to almost nothing. could my impeller be the problem

The pressure you are reading is the pressure in the filter tank as water is pumped though it. When the filter is freshly charged, 9 PSI is a good pressure.

As the filter removes particles from the water the filter gets "dirty" -- it takes more pressure to push the water through it thus raising the PSI.

I think you are viewing this in reverse. Low filter pressure is "good" (as long as it stays above 8 PSI) -- as the filter cleans the water the PSI will increase -- when it gets to 15-20 PSI it needs to be back-washed and recharged.

The pressure drops when the pool cleaner is connected because pool cleaners always pull in air (in varying amounts) because of all the hose connections. This causes your filter/tank pressure to drop.

SOURCE: No water coming out when I backwash. I cleaned

water level must be about the discharge (eyeball) in the pool to back wash. Check the hose connections to make sure that hoses off the the filer head are going to the right place Look for the words "Pump" , "pool" and "waste" molded into the valve. I've seen it a number of times where "Pump" and "pool" were connected the wrong way.

SOURCE: Motor Hums,No Run

Inside the back case on the motor you'll see a white piece with two copper colored arms that have two silver points that almost touch. If these are rusty I've found that the motor won't turn over
. A quick fix is to take some 600+ grit Aluiminum oxide sandpaper and give each of those contact points a brisk sanding to remove any oxidation. This will help the points make a positive contact . Make sure while very obvious that the motor is unplugged first.

SOURCE: Just cleaned filters and reinstalled

How old are the cartridges? They last 2-4 years depending on operating conditions beyond which no amount of cleaning can bring them back.

To check your impeller simply remove the six bolts holding the motor and moving parts of the pump into the housing and pull the motor back out. The diffuser sits over the impeller and it may be there or still in the housing. It aligns over the impeller with pegs and only fits properly in one orientation. If it is over the impeller pull it off and check all the impeller vanes for debris. Clean it if necessary.

If there is nothing in the impeller consider replacing the cartridge or the possibility you now have a clog somewhere else in the plumbing.

Where can I find a Wiring diagram for hayward super II PUMP AND BOOSTER PUMP to new t106 intermatic and existing t104 for the booster?

Not sure if you will find such a diagram...
New installation?
Do the pumps have their own breaker?
Is your Super II pump a 2 speed?
What is the Thermostat for? Do you have a heater that you are trying to connect, so that the pump will come on when there is a demand for heat? Not really sure what the T-stat is mentioned for here?
You still only need to have 2 timers if I'm not missing something?
The T-106 will be for the Super II pump (presuming it is a 2 speed version) It will turn hi speed, on & off. or switch between them rather. I think I see why you may be inferring about a 3rd timer? You don't want to have pump running on "Low" speed continually. If so, Then you will need a 3rd timer (T-104) to provide power as Line to the T-106. The other T-104 will be for the booster pump for your cleaner.
The power for the Super II pump from the breaker will go to the 1st T-104 as "Line". Then from the Load portion of that timer, you will wire into the Line portion of the T-106. Following the instructions from the diagram at this website address for a PDF document:
you will complete the wiring to the Super II pump via the "Load" side of the T-106
The 2nd T-104 (pool sweep pump) will be wired: from the breaker to the "Line" portion of the timer. From the Load portion of the timer, you wire to the booster pump.

Good Luck

Four winds. My pool pump will not start on the low side when I push the button. It will work on the high side. Also it will pump on the low side automatically after I have run it on the high side. ...

The motor starting switch is probably failing on the low speed side so as long as motor is running on high after starting on high it will continue to run if switched to low. You can try to replace the switch or take the motor to a local electric motor repair shop for them to quote the fix.

Suspect programing error on Honeywell TH8320U in Aux cycle

Not making any sense. I don't think you have any programming error because as you said the blower DOES kick on, then begins to shut down before ramping up again. I would have to guess it is internal of the AHU. With that being said, you jump the aux heat and it works fine. I would check high and low voltage at the motor and be sure you are not losing anything when in normal operation. Then, possibly determine a bad motor????? Good Luck, got me puzzled too!!!

There should be a wiring diagram on the motor itself. The colors of the wires vary depending on voltage and model. Generally you have a med/low and med/high setting, I'm not sure what you are getting to with the low/high setting unless you are trying to set up staging. Check the motor for a diagram, if that is not present post back with all of the wire colors coming from the motor and the voltage.

There is no cheap fix for a burned up'll need to replace it. You can replace just the motor for about half the cost of a whole new unit. When you replace the motor you should replace the pump seal as well. Your motor number should be UST1152 for the 1.5 HP and the seal number a 201.

Hayward Super ll Pump - shaft spins opposite direction when it is running, what can cause this?

The only way a motor for these units can run backwards is if the internal lead connections of the winding are reversed. On some rare occasions I have seen a failed start cap cause a motor to start in reverse but turning it off and on would fix that. If your start cap checks out OK and the motor is truly running 'backwards' you will need to replace it.

If on the other hand the flow is not going the correct way look into the valves and filter(s) for issues.

220 V Single phase/cap 4hp two speed A.O.Smith motor problem

It is a capacitor problem. Motors use capacitors to start. Your 2 speed motor should have 2 capacitors (or 1 capacitor with more than 2 connections). Changing this capacitor should solve your problem.
