Cleared for the ILS to Runway 6. Intercepted the LOC and GS (Glideslope). Crossed DANDY at around 1700. DANDY has a mandatory altitude of 1500. If you are on the GS you will cross DANDY slightly above 1500. Weather was marginal and focus was on the approach and remaining on the LOC and GS. Altitude deviation was not intentional. This mandatory altitude at DANDY needs to be removed or changed to meet the GS altitude.
CE560XL Captain reported becoming distracted after capturing a false localizer signal during the ILS Runway 06 at TEB. The mandatory crossing altitude of 1500 ft at DANDY was forgotten and the fix was crossed at 1700 ft.
