2151   Warning: Interface Vacuum is too high.

The vacuum pressure (IF/BK) exceeds the limit (In Analysis Mode).

Check vacuum pressure (IF/BK) for the following possible issues:

• The orifice of the sampling cone is too big.
• The seal of the sampling cone is incomplete (Defective gasket).
• The plasma is too far from the sampling cone.
• The foreline pump oil level is low or the oil is dirty.
• The vacuum tubing has failed (the tubing is off, or a leak is caused by an incomplete seal such as a pin hole or a defective O-ring).
• A drop of water was introduced into the vacuum chamber.
