Re: Aria pumps overheating

Hello,
we have had a similar problem when Aria was first installed - only in our case the whole
pump not only overheated but went in a puff of smoke and took the "motherboard" of the
fluidics cars along with it. As in Jay Myers's, it was a faulty valve that was causing
the problem.

Hi William,
We have had this problem as well in the past.  One or both of the pumps were replaced but
the problem kept coming back.  The service tech. finally determined that it was actually
a problem with one of the valves (if I remember correctly).  There are four valves in a
row with a fifth one slightly offset just below and to the left of the pumps.  The fifth
valve has an extra port coming out of the back.  It was that valve that needed to be
replaced, I think.  It may have been that it wasn't allowing enough of fluid to get to
the pump causing it to overheat.  Anyway, the bottom line was that in our case, it was a
valve problem and not any problem with the pump.
Good luck,
Jay

I'm curious to know if anybody else has had problems with their Aira
pumps overheating and, if so, how was the issue resolved? The pumps
that I'm referring to are the ones inside the fluidic cart, behind the
access door, in the upper right corner.
We have had the 2 upper pumps replaced twice. In addition, the circuit
board that controls the pumps has been replaced and the issue has
remained. The service engineer said that he would replace the cable
between the pump and the circuit board, however, this has not happened
as yet and I doubt that this will be the solution to the problem. The
upper pump is so hot that you cannot hold your finger on it for more
than a second and I fear that there will be a fire or that the pump
will fail in the middle of a sort. Today there was an unusual smell
coming from the instrument when it was turned on. Any ideas from anyone?
William
