Intelliflo SVRS Pump not able to ramp up without help

The "alert! unclog drains" signal keeps coming on everytime the on button is pushed. If I push reset and then on several dozen times the pump may start up and everything runs fine until it is turned off and then the whole process has to be started over. I need help please. Thanks Darold..

These pumps are very sensitive. If you are pushing the on button and the pump trys to prime and then the alarm kicks on I would check the following:

Water level in pool
Make sure skimmer weir door are not stuck in up position

Most Likely Cause
Diffuser oring needs to be replaced on pump. Easy check - shut power off to pump: remove 6 bolts that hold seal plate together (2 on top and 2 on bottom of each side of seal plate with no nuts, and 2 in middle on each side of seal plate with nuts) do not remove bolts that mount motor to pump. Once 6 bolts are removed, grab motor and pull motor unit away from pump. You will see a cone at the end of the assembly with an oring on it. Make sure the oring is snug, if not replace. This is most likely what is causing your problem.

Alarm on pentair intelliflo sv+svrs says clear drain before restart. pump shuts and displays this message after priming and ramping down to running speed. flow seems to stop then backwashes before shutting...

I don't know why yours is giving you this indication but I have seen one do this when its DE filter needed to be backwashed. I am guessing that anything that restricts flow could cause this issue. I hope this helps.

Intelliflow pump shuts off consistently when I connect my Barracuda cleaner, at all pump speeds. Might run for five or ten minutes tops.

The Intelliflo SVRS will do this everytime. The SVRS part of the model indicates that it has a Safety Vacuum Release System integrated into the pump. This means that whenever the pump senses a change in the vacuum pressure (when you connect your barracuda this happens) the SVRS kicks in and shuts the pump down.
If you want to avoid this, you either need to disable the SVRS in the intelliflo menu, Or simply push the "quick clean" button and it will run constantly with no SVRS for 1 hour.
Below is the link for the manual on this pump, this will tell you how to disable the SVRS function if the 1 hour quick clean is not sufficient time to clean your pool

I have intelliflo VS+SVRS pool pump, after stopping for 4 days i want to start again & after start it goes to priming & then alarm & it says clear the drain & restart

There is either something blocking the suction side of this pump (blocked valve, strainer, strainer basket, leaves on main drain.) or the pump is not getting primed in the aloted amount of time. You can increase the priming time on the pump, or manually prime it, or just turn off the svrs feature temporarily until you get a good prime again. If you need the manual to figure out how to do these things, here is the link.

Pump will work manually when you turn it on but will not come on all the time with a intermatic time clock. no power light on speed light, timer is in on position, reach down press desired speed and start,...

This pump cannot work with a mechanical timer alone.You would need to use a pentair controller to use this in the fashion that you desire. The intellicomm P/N: 520641 is the cheapest way to accomplish this feature. However, if you have the intelliflo vs-3050 WITH SVRS then you simply need to program the timer to come on and off when you want it to. If you have only the VS-3050 with no SVRS , then you need the intellicomm module. Just incase you have the vs-3050 with SVRS, I will post the link for the manual so that you know how to program the timer. Any other questions, im @

We lost our password for our Pentair IntelliFlo VS SVRS pump, part No. 011017. Our serial No. is 03321380901156. Please help us retrieve our password. Thank you.

On the normal vs-3050, you need to reset the whole unit. You do this by holding all 4 speed buttons for 30 seconds. After thi, shut off the power at the breaker. let sit for 2 minutes. Restore power and all setting are reset. I cant find any information about the SVRS model, but it should work the same way.
