If there are air bubbles blocking the flow of water through the DI water pump, the
pump may “squeal” or emit a continuous noise. This problem is more likely to happen
when the DI water reservoir has not been filled properly. If the pump begins emitting a
noise, try the following:
1. Turn off power to the Analyzer and wait 15 seconds.
2. Restore power to the Analyzer. Cycling power causes the DI pump to stop and start,
potentially freeing a trapped air bubble. If the noise persists, turn off power to the
Analyzer again.
3. Open the Analyzer front panel.
4. Check for large air bubbles in all the tubing that connects to the DI water reservoir. If large
air bubbles are present, tap or manipulate the tubing to work the air bubbles out.
5. If simple manipulation of the tubing does not free the air bubbles, disconnect the fitting
that connects to the DI water reservoir. Raise the tubing so that it is higher than the
cartridge and remove the rubber vent cover. Move the tubing lower than the DI water
reservoir, to force any air bubbles out of the tubing. Be prepared to raise the tubing
quickly; as soon as all air is forced out of the tubing, water will begin to flow out of the
tubing.
6. Check the level of the DI water reservoir. If the water level has dropped below the
Full
line, remove the rubber inlet cover from the top of the cartridge, add more water, and
replace the inlet cover.
7. Restore power to the Analyzer. If the problem persists, repeat steps
Using the Diagnostics Menu
The Analyzer provides a series of screens to test individual hardware features to ensure
normal operation. This variety of individual modular analysis can help identify
troubleshooting issues and/or eliminate possible causes to help further isolate the
troubleshooting issue.

available: System Tests, Service Diagnostics, and Level 1 Diagnostics.
