Laing D5 needs push/shake to start - Page 2

post #11 of 18
Thread Starter 
Well, cleaning didn't help.Wondering if that splintered edge (around the socket on the impeller) might be the reason. If I open the back, it looks like as if the PCB is glued around the edge. So getting it out without damaging the body or the PCB might be quiet difficult. Anyone knows how to completely disassemble the pump?

I've never seen anyone to remove the PCB on D5s, perhaps you might want to go to xtremesystems.

Were you able to clean the bearing? I've got a dirty D5 and it's really hard to clean.

If you mean the white ball, yes. Every time I put the impeller on, it was again black. Took quiet a few Q-Tips to get it completely clean and stay in this way.
Is your dirty D5 running fine?

I just use it for testing, it was given to me by a friend that got it when they first came out, so it's rather old. I'm trying to get a PWM D5.

Did you clean the impeller too? I haven't tried that, but there are parts of the ceramic ball that I can't get the dirt out.

Yeap, totally clean. I did put a drop of oil (the kind of oil you use for electric hair trimmer), mounted the impeller and turned on the pump. De-mounted the impeller, cleaned the little sphere and the impeller. Then I mounted it again, turned the pump on and repeated the process.

Oil but no water? I mean, bare pump, no water cooling loop? I saw that in the Aquaero 6 video, but I'm not confident enough to do it.

It's not like you let it run for hours. It spins so fast, that 1-2 seconds are enough. The tests to see what the problem with the pump is, are done with a small loop

Any news on your pump?
