If you mean a fluid leak, then check the sensor in the column compartment, most leaks occur there. These must be dry; if wet, soak up the fluid and let air dry, then turn on again.

Second would be to make sure the autosampler isn't leaking at its needle/seat or at its rotor valve, if so, check its leak sensor as above.
