Hello Roger,
I recently purchased a group of used Tunze equipment from another hobbyist to add to what I'm already using. The pumps were from a system that was dismantled, and they were not cleaned before being stored dry, so they were covered in calcium deposits. After a long vinegar soak and thorough cleaning, one of the 6100s still does not run.
When I plug it in (without the controller) the propeller kicks back and forth a few times, with intermittent beeps from the driver unit. After a few seconds, the pumps stops and the driver alarms continuously. The propeller assembly does rotate by hand, although there is some resistance at one point through the rotation.
I started swapping parts between this one and a working 6100 to help isolate the problem.
-swapped out the driver, same result.
-swapped out the impeller, same result.
-put the bad unit's impeller in a working 6100, and confirmed it works just fine.
Before replacing the motorblock (6100.10), any other suggestions?
Also, I notice that there is a certain amount of "wiggle" with the propellers on all of these pumps (6100s and a wavebox pump). Is that a sign that of worn bearings, or normal? The wavebox pump in particular is a little noisy when running, like the magnet assembly is moving around too much.
Thanks,
Jeff
