How long to vinegar bath jebao wavemaker

[DottyClown]

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?

[DottyClown]

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.

Did you open the cage / housing & drop the ceramic bushing? It's a common problem.

so, it won't turn anymore.

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?

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. Cheers

Very common

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 all the good sharing! I'm using a Jebao RW4. Getting slimy.. may need to clean it real soon to prevent clogging the turbine..

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.

Good thing they still replace. Good service from the LFS.

[DottyClown]

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.

[DottyClown]

Worried if the body will crack,water goes into motor, short circuit and fries livestock....

[Schwantz]

My RW4 also stopped spinning after 3 months . LFS said sand will cease the propeller resulting in the motor burning out.

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.

[DottyClown]

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!

i dip it for approx 2 hours, brush it, and dip in RO water for 1hr, then it's back to DT.

[DottyClown]

Guys mine is also like this.. how much does it cost to change to motor?

Mine was under warranty, so was free motor exchange. Do not know how much it would cost otherwise.

common for jebao products.. had a jebao return pump.. died on me after 2mths. changed to eheim, much more reliable.

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.
