One temporary solution I tried before was to reverse the flow from the heat exchanger to remove whatever could be clogging the lines, if the flow is being impeded.  After reattaching the correct way, drain and replace the fluid with fresh fluid and check if the flow is what it should be.  I am not familiar with the Elan instrument or what the correct fluid should be, but somewhere in the software there should be information on what the water flow rate should be and what the sensor is measuring.

Not specific to that model - my experience has been that 90% of the time it is a faulty flow sensor rather than true reduced flow.

Subject: Low Water Flow - Elan 9000

Hello

I am setting up a used and refurbished Elan 9000 and new at this instrument brand. The plasma ignition sequence is shutting down  and the "Diagnostics"
say "low water flow". I am not sure if his is a water chiller problem or something in the ICP and was wondering if anybody has some guidance and experience with Elan 9000 and how to find out why the water flow is low?

Thank you,
Birgit
