).
3. Check that the waste valve is closed.
4. Prime the pump (see Section 5.16
).
5. Restart the pump.

Batch > Stop in Chromeleon.
2. Try to toggle the valve from position A to position B by clicking the
corresponding buttons on the Dionex ICS-1100 Control panel in
Chromeleon (or by clicking the Valve_2 commands under Pump_ECD in
the Commands dialog box).
3. Turn off the Dionex ICS-1100 power briefly and then restart.
4. If the problem persists, repeat Step 2
