Gulf Coast Englewood 8000 Gecko pack issue / pump issue
I bought a Gulf Coast Englewood 8000 in 2001, last summer (July 2008) the spa stopped working, I've been busy so just now have time to diagnosis/fix. Drained all the H20 for winter (I live in Michigan).The Pump 2 works, the pump1 does not, I can hear a relay try to kick in but nothing else happens.Please advise me some diagnostics steps.Here are some picts of the control:I also got this error codeHere is pict of my spa pack:

Re: Gulf Coast Englewood 8000 Gecko pack issue
U need to first determine if there is something wrong with the control panel or the motor. You could start by plugging motor1 into the place where motor2 connects. Or by checking the voltage at the motor1 connection when pumps are turned on. Not uncommon for motors that old to have problems.

I'd just wait 2-3 minutes, re-set it and seemed to work fine. I've taken the GFCI box apart, all wires securley connected. I've checked the leads into the gecko pack, all secure.These 2 picts I took just today.What to check next?(thx for advice)

I've made some short YouTube Videos to help diagnosis, I'm feeling Pump1 is bad more and more.....[url:z4zq4foh]http://www.youtube.com/watch?v=M3pekqCRSb0[/url:z4zq4foh]Pump2 works fine, and control on top turns Pump2 on when plugged into the Pump1 or pump2 connection end, so appears the top control is fine?[url:z4zq4foh]http://www.youtube.com/watch?v=87MO4QQoHSM[/url:z4zq4foh]Pump1 tries to kick in, you can hear it go hmmmm, then kick out.[url:z4zq4foh]http://www.youtube.com/watch?v=mSEQjoyNgK8[/url:z4zq4foh]

Re: Gulf Coast Englewood 8000 Gecko pack issue
What I would do is pull the motor (and pump) and check it out. Pull the end off the motor and have a look at all the wiring. Its not uncommon for the centrifugal thingy to get loose or for some wiring to come loose. If nothing else you can power up the motor (carefully so as not to electrocute yourself). Or take it to a shop that can check it out (an electric motor shop not a hot tub shop). Do not run the motor with the pump attached for more than a few seconds - you can destroy the pump. Another thing to check is the heater. In my limited knowledge if you check continuity between either of the connections and ground and get anything other than an open circuit the heater is shorted out. internally (assuming you have a 220VAC system not a 110VAC system). Hope that helps.

Re: Gulf Coast Englewood 8000 Gecko pack issue
Denny;Thx for your help, I appreciate it.What a nice way to spend Sunday mid-day, working on my hot tub......at least it should be working soon.I think you appreciate things more when they don't work and you go w/o them for a while.Took off Pump1, as I was undoing it the white gasket on the pump side was crumbled and I can see how it leaked, looks like that accelerated pump failure:In process removed spa pack unitThe middle gasket here shows what I call failure mode, honestly it looks like bad install job, it's never been serviced.I'll get all new gaskets to make sure.Pump removed.It was siezed, I took the vise grips to the shaft between the elect motor and the H20 impeller and was able to un-sieze it.Lots of corrosion there.So now I need to get replacement pump, I wonder if the pump impeller portion is sperate or comes with the pump? Guess I'll be calling Tech Support: 813-235-4574 Parts: 1-866-364-9681 Monday to find out.I have no idea what $'s to expect either.Again, Denny thx for your help.Admin/Mod:Shold this thread be moved to another sub-forum here (bad pumps) or "ok" to keep in this forum for consistency?

Re: Gulf Coast Englewood 8000 Gecko pack issue / pump issue
I tried to take off the front H20 Pump portion, I'm stuck.Took off the front 8 screws, removed the faceplate, there are no apparent fasteners inside.Is it held on just by the pal nut that appears to be holding the pump turbine itself to the shaft??I don't want to break anything.By the way, when you look at the bottom of the pump clearly there was H20 leakage....So, my shaft seal went bad, caused my pump motor bearing to sieze....can I just replace that bearing to save some $$$'s?Edit:I'm reading in the "Pump Issues, Jet Pumps" sub-forum, [url:3a5nn2kx]http://spaforums.com/Spa-Repair/Pumps[/url:3a5nn2kx] , how to remove the impeller - there are a few threads there with exact same Q as mine, hopefully I can do it.

Re: Gulf Coast Englewood 8000 Gecko pack issue / pump issue
It looks to me like you need the whole schmear, pump and motor. They generally come as a unit and most places recommend you buy them together to avoid problems. Try Discountspaparts.com and there are several other internet sources for spa parts. Compare price with your local dealer and buy where you can get the best deal. It looks like the seals in your pump have been out for quite some time. In the future its a good idea to keep an eye on them and if leaking fix it. Now to the pump impeller, it unscrews but you have to secure the motor from turning to unscrew it. I took the electrical stuff off the other end of my motor and used (cant remember if it was vice grips) or something to stop the shaft from turning. IIRC the impeller has reversed threads and unscrews the "wrong" way. Good practice for future seal replacement jobs but like I said I think you need to but an assembled pump and motor. Probably 200-300 bux - not a bad deal. On the positive side you are getting an education in how the spa comes apart........... BTDT.

Re: Gulf Coast Englewood 8000 Gecko pack issue / pump issue
I do have a 4hp Waterway pump impeller, from what I can make on the inside center portion of the impeller.Pt# 310-4190. circa late 1990's or early 2000's, since I bought this tub Aug-2001 from a warehouse dealer (my loghome builder knew him) I suspect my tub is late 1990's manuf.Ha, the 5HP sticker on the outside of the waterway housing is a lie (earlier pict in this thread), the molded 4hp must be the real spec.The impeller spins clockwise to shoot water out the center hole, so the threads are not the std "righty tighty, lefty loosy", but reverse so they stay tight.(like you stated)google found the impeller manuf website, [url:2pq9wdv4]http://www.waterwayplastics.com/[/url:2pq9wdv4].I'll do as you recommend, check local vs web. I do like to support local person, but if their mark-up is too high I'll go with web.Yea, I'm taking ownership of my spa, and learning/saving $'s in the process.As an Engineer, I wonder what the mtbf design spec for the pump seal(s) are? 10 years?The pump1 has high duty cycle.edit:This site has good schematics, [url:2pq9wdv4]http://www.aqua-man.com/schematic.asp?kc=S1938[/url:2pq9wdv4]Mine is the current style

Re: Gulf Coast Englewood 8000 Gecko pack issue / pump issue
Interesting that HP is printed on the pump. Seems like pumps don't make HP, motors do. Maybe that is the recommended motor size for the pump. FWIW, while they rate these motors at 4HP I think that is startup HP and actual HP is more like 2. MTBF, well my first replacement was 4-5 years after I bought spa new in 2000, next was last year, so MTBF=4-5 years. Fortunately they are cheap and pretty easy to replace. Sounds like you're well on your way to a working hot tub.

Hiring a Bankruptcy Lawyer?
Are chapter 7 attorneys like this [url=http://www.bankruptcyattorneys.org/:3kta9nqk]san diego bankruptcy attorneys[/url:3kta9nqk] definitly worth what they charge or could you just go with doing it yourself?

Re: Gulf Coast Englewood 8000 Gecko pack issue / pump issue
The picture shown is very familiar -you have a leak problem - nobody knows this but check your top contro panel - most spas leak through this onto the master board thus causing the ground fault to kick in - and water leaks directly onto the main electrical panel and brains of the hot tub - go underneath and tighten the top gasket as these become loose with the vibrations of the blowers - then use clear caulking all around and on the surface around the gasket to prevent any water from leaking in . Then take a hair dryer and completely dry all wiring inside and the GFI - - then install a sheet of plastic over top the the electrical unit to prevent any further leakeage falling on the panel - GFI's are very sensitive - make sure your posts for the heater have no corrosion on them - as this will cause the heater to be faulty and the GFI will kick in - - one way to test this is unplug the electrical to the heater and individually check the electrical for your blowers, ozinator and pumps - if all work then it is either your heater element corroding the posts inside or your pressure valve - in Canada - a company is available through Pioneer Family Pools for Gulf Coast Spa parts - centralspasupply.com - go through your dealer - they have everything - hope this helps - you can save a lot of money doing a minor job yourself.
