EcoStar SVRS "Drive Error!" Autoprime Failure

Postby TSH Tech » Sat 26 May, 2012 18:28

I make this entry for posterity

Pump:Hayward EcoStar SVRS

Problem: Pump throws an error code "Drive Error! - Autoprime Failure", halts the pump and does not continue into timer modes.

Cause: Homeowners solar system is mounted on the roof, a 2.5 story rise from the pump/filter. Homeowner's solar system is a manual type, always on configuration. The rise to the solars is enough back-pressure for the pump's software to think it's not priming, therefore it throws an error code. When the solars are switched off, the pump runs normal and does not throw a code.
I blame Hayward's engineers for not taking into account real world dynamics.

Solution: Have the Hayward instruction manual available(IS3400VSP Rev-C)
Page 18, Part 5.6, Step 9

-Press [MENU] to get to the "Configuration Menu Locked" display
-press and hold down both [<] [>] buttons for a few seconds until "Configuration Menu press > to enter" is displayed.
- scroll through the items until "Set max-speed Prime, Period: Auto Sense" is displayed and press [+] to change from Auto Sense to 3 minute mode.
- exit out of the menu, save any changes if prompted
- Problem will be solved, enabling timers to function as normal.

Notes: I have never run into this type of issue before with a variable speed pool pump. Usually I install Waterway Econoflo VSA pumps for many reasons that benefit my clients and make it easy for the pool techs to service the filter equipment. But the one day the warehouse is out of stock, I went ahead and took this Hayward EcoStar SVRS which is comparable, only to find out it would cease to function based upon the above problem; and then turn my clients pool cloudy on this Memorial Day weekend. I go in for ear reattachment surgery this Tuesday.
Hayward, you need to get your act together. It's not clear the purpose of the Auto Sense mode, but nowhere in your documentation do you list or acknowledge that the problem described above is an issue with your pumps. Nor do you make it aware if certain types of scenarios exist, the error code will be thrown. In my personal opinion, you could delete the Auto Sense from your Auto Prime software, or just allow the end user to adjust the RPM's within 2700-3450 rpms while it performs a do-or-die 3 minute Auto Prime session before switching to timer mode.

This is great information, thank you for sharing! I haven't had the opportunity to service or install any EcoStar pumps yet, but this is getting printed out and added to my notebook.

This is good feedback, glad it has helped!

I've installed a few more since this posting, mostly to match the AquaLogic timer communication features and have not had to adjust they Auto Sense Prime. Those pools did not have solars installed either. Seems if there is unusual amount of back pressures, it's enough to mess with the pump software.

Thanks - I have been struggling with this since they installed my Variables Speed - numerous numerous failures - now running like a baby - I'm going to run ithy 24/7 with low speed at night - high speed in daylight to let Solar Driven Heat Pump keep it toasty - Thanks for the post.

Thanks very much for sharing your knowledge. I am an inexperienced do it yourselfer who installed my first pool pump. I chose the ecostar and it has been failing to prime. Was really getting worried since its getting below freezing and afraid pipes would burst without pump and heater kicking in! Thanks, it worked like a charm! You da man!

Thanks for this post. Although I don't have a solar heater, your post sent me in the right direction. Dirty filter!
My ecostar is only about six months old and has worked well since I installed it, but after a big wind storm that caused waves in the pool it would fail when trying to prime. I checked for an air leak and tried several other things when I saw your post and started thinking about back pressure. Although the pressure gauge was at less then 20 pounds, cleaning the filter solved the problem. Might bee time for a new gauge.

Thank you very much for posting this. I have been noticing the drive failure issue more and more lately and just this morning isolated it to the solar. However, without your post I would not have known that the "AutoSense" feature could be overridden, nor how to do it. Thanks for providing such a comprehensive post!

Thank you. I had called my pool man who thought there was air in system and the solar guy who said it is not the panels. It now is working!!!!! Perhaps you can write a user guide that we can understand! I have a large pool with solar panels, what should I set the speed for on the pump?

Hey AmhowardAlan, well, when I write these help entries, I try as best as possible to make it so that a pool owner with no experience can follow the step-by-step instructions to get to the right to the core of the problem and solve it. Many times, these pool on-board computers with their menu systems are not intuitive. I have background as a Silicon Valley computer technician solving highly technical problems that normal people can understand, so that's as easy as I can get. :wink:

For your solars and having a large pool, set your solar speed anywhere from 3000 rpm to 3450 rpm and that will get your pool heated.

Thanks for the tip.

I spent 2 hours trying to figure out what the problem was and was ready to take the unit back. I reprogramed the unit and I was up and running in minutes (3 to be exact). I guess I should have checked here sooner. I also have solar panels on the roof of my house as well.

Thanks Again :)

I was COMPLETELY frustrated, and pissed at myself for buying the "more expensive yadda yadda all the fixings" pump to replace my base model which broke down after many years of service.

You saved my sanity OP. Thank you, and thank you again.


P.S. What a stupid company to have this set as default.
