Just had to replace our Polaris 380 cleaner and got a really good used one. All seems well except it climbs much higher than the other one and gets stuck on the love seat edge and at the top of the tile just under the coping. RPMs were low so I removed the blue restrictor plate thinking it needed more 'umph' to move off but it does not really move that much faster. We have plenty of water pressure. . The thrust jet is set at 11. I have had these cleaners for 27 yrs and this is stumping me. We did not replace the feed hose because it was cut perfectly for the pool and it has no leaks so why mess with it. Back up valve works fine but just having it stuck like that for a couple of minutes means it sprays and sprays. It never needed a tail weight before so don't want to do that. It also gets stuck on its own hose on the bottom and can't roll over it.
Thanks for any ideas
