Dolphin E10 - thoughts on this cable (repair concerns)?

[Pauls234]

Something seems suspicious.

Back in May my brand new Dolphin E10 quit after maybe 4 uses. (Thread here: Dolphin E10 new, suddenly won't start)

It was repaired under warranty by a local service (suggested by Dolphin). He told me it was a bad cable, so replaced it.

It worked well for about a month (again 4-5 uses) and then just died again, exact same symptoms as previous - power supply light would come on, but the unit wouldn't move. Called Dolphin and asked if they would just replace it given that it has broken twice now in 10 uses. They had me send it in to them for evaluation. Came back to me a week or so later with a work order that basically said they tested it and nothing was wrong other than the float was in the wrong position. It works fine now (at least for the 3 times I have run it since) but I have a hard time believing that nothing was wrong, but can't really prove anything.

I do not recall the cable having this bulge or splice near the plug but I can't say that for certain. When I check google images I see some cables with and some without this bulge. Anyone have thoughts or insight as to whether the cable is the stock or has been repaired?

My concern is that I have a lemon and I just want an accurate record of its repair history. I emailed Dolphin for a follow up and they just reiterated that they tested it and nothing was wrong, so they sent it back.

I don't have that model, but the cord on this video looks the same (right around the 16-second mark):

Mine has that bulge section. It looks like a Ferrite core used to quiet down any signal interference.
Commonly seen on computer monitor cables.

Having them say they tested it passing with flying colors is concerning.

Have you been able to repeat the failure if you test the E10 with it plugged
into a different outlet? Just thinking out loud for suggestions to try.

EDIT: saw in your other thread you did try other outlets.

Thanks for the replies.

I did try other outlets upon the 2nd break down as well and it never ran. Except once. After I let it dry for a while, I plugged into a garage outlet and it started moving on the ground, out of the pool. I then dropped it into the pool and it would not run and I tried multiple outlets with it in the pool as well. Nothing. I then let it dry out for a while and tried to run it on the ground again using multiple outlets and could not replicate. It was just dead.

Believe me, with how little use of this thing I have had since purchase and the short swim season, the last thing I wanted was to be without it for the 2nd time in 6 weeks, so I exhausted all home troubleshooting.

It works fine now since Dolphin sent it back, but it is hard for me to believe it just repaired itself in transit.

Other alternatives are:

-There is still something wrong with it that will resurface eventually, or....
-Some kind of user error on my part that I did not commit the first several times I ever used it, then committed over and over again when I was being very deliberate in testing it before lobbing my 2nd warranty claim, and then when it came back from Dolphin, I suddenly stopped committing this user error.

That seems highly unlikely so I am trying to reason through other alternative explanations.
