Just wanted to update everyone... after more than 3 years, my LX WE14 is still working fine. It is slightly bigger than the original Laing pump, but honestly I am very happy I had no failure since I changed it.

Thanks Jersey Hot Tub Repair for your comment. RDspaguy already mentioned I probably was having issues with my water from time to time, but as I wrote above, I had 3 failures with Laing pumps in 5 years. This is really too much for me, so I am willing to give a shot to another maker... Laing pumps cost around 400 US$ in Switzerland, so this is really driving the cost of the spa high! Thanks to all of you for those useful advices.

Nice places, too! But yes you really get snow there... I still have the feeling that often spas are not designed to function in really cold weather - I use mine a lot in winter, but there really should be a way to prevent the spa from freezing when there is a heating problem. Having an automated procedure to simply turn on all the pumps every hour if heating is malfunctioning would be smart. Then my spa is 12 years old, perhaps such option exists in newer installation...

Of course not. In Switzerland. So access to spare parts is limited - I almost have to order everything from abroad as local supply is either inexistant or extremely expensive (to give you an idea, I bought my last Laing E14 locally for around US$ 400...)

@RDspaguy, if I may borrow a little bit more of your knowledge... How about using a pump like the WE14 LX... https://www.hottubdiy.co.uk/lx-we14.html It surely won't be better, but at least it is more affordable if this becomes a consumable. Do you think it is a bad idea? Thanks again!

I would take such an offer, but being in Europe, the overall cost might be too high By no mean am I a spa specialist, but I have some quite good knowledge on water chemistry - thanks to a Ph. D. in chemistry... I agree that the material is corroded by the water, but if this is happening although my pH has always been between 6.4 and 7.8, then I still believe that pump is crappy... I use a home-made chlorine dioxide (after buying the mixture in the past, which has the inconvenience of requiring pH adjustment); my chlorine dioxide is pH neutral, and because my water is really hard, there is little variation of the pH over time. When I measure the pH, I do it in my lab, so the result should be realible; but clearly I do not monitor every day. I also use small quantities of a product called SpaBalancer, which is effective in maintaining the quality of the water. I am not questioning the fact that you can always do better with the water control, but the material should be able to handle some minimal changes in the water. After all, this is a spa... And clearly, I will welcome any advice. If I understand you, changing the pump for another brand would not help, right? Thanks!

Thanks for your comment. In my case there is a clear and repetitive rusting issue with the part linked to the propeller - likely iron - which is protect by à think layer of metal, disappearing overtime. Not sure how I can post pictures of that part. Is anyone aware of a pump replacement from another maker? Thanks and best regards

I know this is an old topic, but I thought it could be interested for those with a similar problem. I have an Artesian Spa Platinum Elite, with an E14 Laing pump for circulation, and in 4 years, this is the 3rd failure I had with this model. It always start with a stronger noise, followed by episodes when the pump can't turn on - and the heating stops, which is really convenient in winter - until eventually the breakers are clearly saying : "Stop"... I opened 2 of those pumps. It appears that the pump is using a magnetic system, and the magnet itself - which should be protected from the water - was rusted on those 2 pumps. My water is extremely hard, but there was no trace of problem coming from that. I simply think that the pump's design is EXTREMELY poor, and that this is an expensive - but low quality - material.
