Hey guys, any of you had a Liang DDC pump just slow down and then (apparently) stop working? I noticed a change in audio pitch last night, and then this morning it seemed to stop entirely. I started a temp monitoring program which, given it showed the CPU increasing in temp, supported the theory that the pump had stopped. I got the machine shut down right away. I'm assuming I'll have to buy a new pump, but I'm wondering if anyone else had encountered this. It's been fine for nearly 2 years; it seemed to die completely out of the blue. Thanks!
PS - I *did* change pump tops from an acrylic top to an acrylic res top a few weeks ago. But it's been working fine and I haven't touched it since then...
