Hi folks
Apologies for the *long* post - but could use some help. I have been troubleshooting a blinking red-light problem with my Hotspring Landmark (2000 year model). I have always had a problem after refilling this spa (everytime after a refill if I flipped both breakers on - the blinking red light would turn-on) - the way I would resolve this is by turning the 20A breaker on, then running jets for at least 30 mins to an hour and then turning the 30A breaker on. Sometimes it would take 2 - 3 times of doing this - but it usually worked.
Then I refilled last month and noticed one of my jet-pumps leaking - I had a local service person come take it out - had to drain the freshly filled water and replace the wet seal and impeller on it. When he came back to re-install it, he accidentally broke the little black nozzle off the right-angle elbow attached to the circulation pump (that connects to the bleeder hose) - so he replaced the elbow and put a brass barbed fitting in it to connect to the hose.
After this I refilled the tub and had my blinking light problem again - and noticed that I wasn't seeing too many bubbles through the bottom drain (they have been low in general) - so did the following troubleshooting:
1) removed the filter and tried - didn't work
2) removed the venturi injector tubing from ozonator check valve -- water comes out of this unless I started Jet-pump-1 at which point the water gets sucked back into the injector..
3) removed the intake hose from the circulation pump and connected it back in to remove any airlock -- started the jets and 10 minutes later started the 30A breaker - did not trip this time.. However few hours later the red-light was flashing again..
4) This time I took out the circulation pump (thinking it might have scale deposits inside or something broken) - plugged the hoses with caps so I didn't have to drain and dismantled the pump wet-end (its a silentflo 5000) - pump looked great - no scale / no deposits / no broken parts.. I took it to my local store and the tech there did a dry test and said the circ-pump looked ok to him.
5) Since I had the circ. pump removed - I decided to check the watakins no-fault heater for clogs too, so I removed it; opened the end caps and it's clean as well; resistance was ~9 ohms.
6) So put everything back together - turned on the the 20A breaker and got a good-stream of bubbles initially but they trickled back to a low stream very quickly after that. This time around after disconnecting the injector tubing at the ozone check valve, water still leaked out even after turning on the jet pump - so something was different than before.
7) Turned on the 30A breaker - didn't get the blinking light - left it running -- of course few hours later the blinking red light was back!!
So I am still thinking it's my circ. pump - just ordered a new Laing E5 repalcement - but in the meantime - I am wondering if something else is going on.. Any suggestions from anyone?
Thanks
