problem: tunze nano wavebox clicking

[rvitko]

I don't recall the details and without an actual name I can't look it up, but I would be sure we fixed it.

When the pumps are made the shafts are pressed into a hole that is half the diameter of the shaft using a hydraulic press, once this hole is stretched out the shaft cannot generally be reliably reseated, we have yet to find an adhesive that will hold up more than a couple years, often the shaft can be pressed in one more time, but that is really the limit.

im having the same problem rodger bought one second hand and mine is clicking to

The 6055.740 disc will stop a clicking noise for sure, this is a newer part and the older 6025.740 disk must first be removed which will require a pick tool (like our 0220.707). Under no circumstance should the shaft be pulled out to access the disc, doing so will destroy the pump. You will need to hook the disk and pull it out.

Hi, I am having the same issue - the nano is new. It started clicking after about a day of use. It is a model 6206. Please help.

On a new nano wavebox the more likely issue is the propeller is sticking or hitting the outlet in the box itself. I would remove the nano wavebox and look into the outlet hole and see that the prop is roughly centered, if it is not and could hit the housing this is the likely cause, it may be a simple as the motor is loose and needs to be adjusted in the housing. The Nano Wavebox is entirely hand made so this is not a common problem, but also not impossible.

If it is not this, it is likely that the factory test run lube (vaseline) has accumulated some gunk and bound the drive unit and simply swabbing it out with a q tip may solve the problem. Remove the drive unit, look for gobs of vaseline in the pumpand swab them out.

Hi Roger, Thanks for your reply, I'm finally getting around to looking at the wavebox. I pulled the motor/base out, reset the propellor in the motor and put it all back together. I did as you sugested and looked to see where the propellor is with respect to the outlet and it is not even close to being centered, the edge of the blade is outside the tube. I tried to adjust but it is were it is - any suggestions? It seems like the motor is too low or tipped forward.

Thanks!

I take it the issue is a thud or click noise? Please send it in, we will replace the motor or housing as needed to solve the problem. This is not common but since the Nano Wavebox is entirely hand made by modding a 6055 and 9002 skimmer housing there is definite human error possible.

If you PM me your name, address and email I can email a return label.

Hey Roger,

Just wanted to say thanks! I got the Nano back and put it in the tank and it works great.
Big waves and not ticking noise. YAY

Thanks!

Hi Roger, You still monitoring this board? My wavebox has decided to stop working i thought maybe it needed to be cleaned so i took it apart and it dod not look dirty at all. I cleaned just in case put it back together and nothing - well not nothing - when i plug the power it it does a quick spin then stops. The control show the normal pump on and flashing lights but no pump movement. I tried spinning the prop and nothing either. it will not spin since the magnetic force is holding it in place. Any ideas?

Thanks!
Erik

Does it spin once again if you give the prop a half turn after it stops?

 

[WolfInRed]

no, but i know what you mean, sometimes you can start them moving them. Was having the issue with my little Tunze pumps but cleaning usually fixes that. The odd think is that it will spin a just a tad when i plug the power into it. Is there anyway to bypass the controller incase that is the issue? Can i plug it into my tank circulator pump control? Should it default to running with out the control plugged in?

You can bypass the controller by accident when you use a 7096 like mine. If the cord leading to the controller disconnects the pump runs without pulsing. I can't remember if you can do the same by disconnecting the controller that comes with the wavebox.
I can't offer any advice on plugging it into your particular tank controller if I don't know what type it is. Roger is the man when it comes to the details.
I had a dud motor block a while back that caused a heap of arguments with the local distributors after it failed in a similar way, but with only half the motor block displaying the symptoms you discribe. It ended with a replacement motor block.

 

[rvitko]

Have you tried removing the prop and magnet (drive unit) to be sure it is not cemented in by calcium build up. Soaking alone won't penetrate the tight space between the magnet and shaft, you want to remove the drive unit and soak the motor and drive unit as separate pieces.

You could see if it works with no controller and while a 7091 or 7095 won't be able to produce a wave, you could also see if it can respond to another controller with one of these (to rule out a pump issue).

 

[WolfInRed]

Thanks for the info - hopefully Roger has some ideas. I have all tunze stuff so might be able to plug the motor into the 6105 controller. Actually now that i think about it I don't think i can. Something about how the Apex controls the speed of the 6105. I suspect it is the motor block I could turn the voltage up and see what happens, it's set at 12V. I have the wavebox multi controller 7096. And some other stuff in the attic LOL.

 

[WolfInRed]

Hey Roger,

Does is run with no controller plugged into power connector like the 6105?
Yes, I cleaned it all - it moves freely except for the magnetic force.
I'm using 6091 to control the wave box.
I have a 7096 as well that i'm not using. And a 7092. I was going to hook the wavebox to the apex but ended up not doing it.

 

[WolfInRed]

I dont have a 7091 or 7095

 

[rvitko]

Yes, with no controller it will run continuously and this would be a good basic test, if it then works it is more likely the controller, keep in mind that it will produce a ton of bubbles unless you fully submerge it for this test or run it in a bucket. If it works with no controller, you could use any of the controllers you mention just to confirm it is the 6091, with the 7092 or 7096 you should be able to produce a wave, the 7092 is the current controller included with a 6206.

 

[WolfInRed]

So it does not run with just the power in except for the half a turn just when plug it in. So it look like the poles are not reversing. The must be some sort of solid state component in the motor housing that flips the poles. Ugh. I guess the motor is bad. I seem to having a string of fish tank devices all having ills after a year and a half. I guess the honeymoon is over. So how do I get this fixed or do have to buy a new one?

 

[rvitko]

Its a bit more complicated than that, there are two coils and a Hall sensor and it essentially works like modern electronic ignition, the sensor picks up the rotating magnetic field and times the firing of the coils (like spark plugs). How old is it? The warranty is 2 years, if you send it in with the receipt we can get it replaced under warranty if it is less than 2 years old. If it is more than 2 years old and we cannot fix it, you can get just a motor and we will discount it.
