13. Reconnect the tubing to the DI water reservoir.
14. Follow the piece of tubing with the obstruction down to the solenoid valve (see Figure 44).
Figure 44: Preparing to Disconnect the Tubing from the Solenoid Valves
15. Place a paper towel under the solenoid valves, as water is likely to leak from the valve.
Remove the obstructed tan tubing and the connector tubing from the solenoid valve.
• If water leaks out the solenoid valve, remove the inlet cover from the DI water reservoir,
attach the water bottle to the tan tubing and gently flush water through the tubing. Be
sure to carefully monitor the water level in the DI water reservoir as you squeeze the
water bottle, as you should avoid over-filling the reservoir. Reconnect the tan tubing to
the solenoid valve and resume normal operation.
• If water does not leak out of the solenoid valve, proceed to the next step.
16. Reconnect the tan tubing to the solenoid valve and disconnect the green restrictor tubing
from the same solenoid valve.
• If water leaks out the green restrictor tubing, the obstruction is in the solenoid valve.
Connect the water bottle to the solenoid valve and gently flush water through the valve.
