The pH may not have been properly measured or the volume of W3 may be too small. Please check the following:
1) That there is 50 mL of solution inside the W3 bottle
2) That the sippers and bottles attached to the instrument are not loose
3) That the color of the sippers on the instrument are gray and blue
If there is not enough W3, please add more until it reaches the 50 mL line on the bottle.
If you are accidentally using the dark blue sippers (for the dNTPs), the tip will not touch the solution, since it is too short. Replace the sippers, press the 'start' button, and if the same message appears, change the chip to a different one and try again.
If you get an error, shut down and restart the Ion PGM System. Discard the solution inside the W1 bottle, make new solution by adding 350 ul of 100 mM NaOH, and restart initialization.
Also, if you are using an Ion 316 Chip v2 on a v3.4 or older instrument, the instrument will not recognize the chip.
