Tunze 6100 Alarm went off

[Logzor]

I came home last night and the alarm was going off on my tunze 6100.

I turned it off - the pump was not running - and removed it from the water. I took the prop out and noticed some thick calcification at the very base of the prop. I soaked it in vinegar overnight and it is running fine as we speak.

I soaked them in vinegar around 4 weeks ago so I do not see why this issue appeared.

Should I keep my eye out for anything? What all should I take apart when soaking these pumps? All I do it remove the front cover and prop.

Here is how to clean it properly, make sure out take the bearing out behind the impeller

If this does not fix it it may need to be sent in to Roger (Tunze USA) for repair

Thanks. After a night of soaking its working great.

After looking at that I forgot there was a bearing down there. I pop it out and there was some calcification on it still.

Is it really necessary to take the actual prop apart into 15 pieces?

I generally don't recommend removing the prop from the shaft. As far as the rest of the break down, I would do that at least every other time( every 6-12 months) to be sure the hole in the middle of the drive unit is clear of lime.
