SRC Member DottyClown Posted February 27, 2016 SRC Member Share Posted February 27, 2016 Need advise. Me jebao rw4 stopped spinning after only 3 months of operation. Thinking to soak in vinegar and clean it, to see if it works again. So how long should I soak it. And do I take it apart to soak, or just put the whole "ball" in?

SRC Member DottyClown Posted February 29, 2016 Author SRC Member Share Posted February 29, 2016 Ok, so I cleaned the RW4 and sadly it is still not working. Only 3 months and its dead, that is very lousy quality. Anyone knows what is the warranty period for Jebao wavemaker? Problem is I have miss-placed the receipt, sigh.

SRC Supporter SubzeroLT Posted February 29, 2016 SRC Supporter Share Posted February 29, 2016 Did you open the cage / housing & drop the ceramic bushing? It's a common problem. so, it won't turn anymore.

SRC Member DottyClown Posted February 29, 2016 Author SRC Member Share Posted February 29, 2016 The fist time it stopped spinning, I took it apart and just rinse, brush and wipe it clean. Put it back and it did start to spin again after some hesitation, but not very strong and strength quite unstable. But less than a week later, it stopped again. So took it apart again and vinegar soak. But this time it just won't spin again. Both times I did not see anything loose and made sure did not lose anything. What does the ceramic bushing look like and where is it located? Quote Link to comment Share on other sites More sharing options...
SRC Member inwear Posted February 29, 2016 SRC Member Share Posted February 29, 2016 I had a similar situation for RW15. I took it apart for quarterly maintenance and it won't start. I've ensure all components attached and aligned. I just attribute to poor make and quality management. Nevertheless the price vs specification is unbeatable. I pay for what i get.

SRC Member sgtayc Posted March 1, 2016 SRC Member Share Posted March 1, 2016 I had my RW 15 since Sep14 which is already close to 1.5 years and it is still working perfectly. Sent from my SM-N920I using Tapatalk Quote Link to comment Share on other sites More sharing options...
SRC Supporter SubzeroLT Posted March 3, 2016 SRC Supporter Share Posted March 3, 2016 A very common issue is losing the bushing after cleaning your pump or motors. The symptom with the missing bushing will be a stalled propeller. The Jebao RW4 comes with a silicone bushing (held by the tweezer in the photo) that is placed at the tip of the propeller. It drops out very easily. In fact, i just bought this replacement bushing from AquaMarin today ($2). An alternative is to use a hard air tube. Do check if yours is a case of the missing bushing.

Thanks for the pic bro. Yes, I still have that piece (bushing). In the end I brought it back to the shop early this week. Believed to be the motor died. They wanted to check if mine was brought in by them(agent) or through parallel importer, before they replace motor or entire unit. Just got a call from them today, asking me to go collect replacement. Hope I have better luck with the replacement unit/motor. Quote Link to comment Share on other sites More sharing options...

SRC Member DottyClown Posted March 4, 2016 Author SRC Member Share Posted March 4, 2016 Just to update. Got the RW4 back from lfs. They changed the motor unit and its working now. Sadly, I believe they replaced with a "old & used" motor, as the physical appearance is not good. Quote Link to comment Share on other sites More sharing options...

SRC Member Schwantz Posted March 5, 2016 SRC Member Share Posted March 5, 2016 My RW4 also stopped spinning after 3 months . LFS said sand will cease the propeller resulting in the motor burning out. Quote Link to comment Share on other sites More sharing options...
kohanson Posted March 5, 2016 Share Posted March 5, 2016 My jebao wp25 have been running since the day i started my nano tank in nov 2013. It has been running on w1 s3 since the first day and I usually take it out for cleaning every 2-3 months and oil it with vaseline at the shaft. Still going strong till today, no regrets and bought a jebao RW-8 in Sep 2015 to run both concurrently for my 3.5ft tank.

SRC Member DottyClown Posted March 11, 2016 Author SRC Member Share Posted March 11, 2016 Just for the record. After I feedback to LFS on the replacement quality. They responded quite promptly and agreed to change the motor again. Collected the new motor today. Have to give kudos to the LFS, great service EOA! 2 Quote Link to comment Share on other sites More sharing options...

I took mine apart and soaked for only 1-2hrs. Then brushed off any coralline that was still present. I removed and did not soak the rubber cushion and bushing. Just to play safe as dunno if these soft rubber parts will be affected by the vinegar. Quote Link to comment Share on other sites More sharing options...
