How to Fix the Clicking Noise While Oscillating

I had the same issue, in the beginning it was barely audible but it got louder over time. I found out there are two kinds of noise generated by the oscillating mechanism. One is a very quiet click that appears at each, or just one end position of the turning cycle. This is due to the tolerances in the oscillating mechanism and can not be solved without replacing or modifying parts of the mechanism. The other noise I noticed, did not happen at an end position and it was more like a rattle/ series of clicks, almost a silent squeak. In my case, this seemed to be coming from the cable connecting the motor with the mainboard. While the base plate and the motor moves against each other, the cable bends and may touch the housing or other parts. Also, there is a plastic clamp, holding the cable in place on the mainboard. I used just a few drips of silicone spray to lubricate the cable and reduce the friction on certain points. It is now absolutely quiet!

For the oscillating squeak-like noise: sometimes simply powering off, holding the base with one hand, then manually oscillating the unit a fraction of the way will stop the noise.

"I had a clicking during oscillation on my TP04. When it would reach the end of the rotation, on one side, it would click as though it was binding. Looking at the filter basket, it had actually worn off some paint. I noticed the gap between the white plastic base and filter basket were not the same.

I tore down the entire thing and found the metal shaft that connects the upper body (filter basket and up) to the bottom base was crooked. Looks like the cause was just poor manufacturing on the affixing plate that the shaft is bolted to. I tried to replaced the washer that sits on the bearing, readjusting the seating, but it would still wobble when spun. It’s hard to tell in the picture, but the shaft sits slightly crooked.

I ended up shimming the affixing plate, that binds the shaft to the entire upper body, with a small washer under one of the plate screws. This offset the crookedness just enough to straighten the alignment going into the base unit. Under one of these, in the very bottom of the top tower, under the motor.

This is basically an entire unit teardown to get to it. So long as you have time, torx bits and patience, you can fix this."
