Monogram uses this alternating pattern for a low water supply on both the UNC15NP nugget and UCC15NP clear-ice machines. The usual reasons are a supply valve left closed, a kinked line or low pressure; on the clear-ice model Monogram adds a spent filter to the list. Monogram ice machine display · also shown as Making Ice / Filter alternating What to do when Making Ice and Filter lights flashing alternately shows on the ice machine ### Kind of code Water supply The water side came up short: the trough did not fill in the time allowed, the float or level probe never saw water, or water kept flowing when the inlet valve should have closed. A supply valve left partly shut, a clogged filter cartridge, low building pressure or a sticking inlet valve are the usual causes. Opening the valve fully and fitting a fresh filter clears the simple cases; a valve that hums without passing water is a visit. ### Usually leads to Ice machine water valve and filter repair The inlet valve, filter, sump float or level probe and supply line, tested and replaced when water arrives short, dirty or nonstop. ### Shows up as Ice Machine Error Code or Flashing Light: What It Is Telling You An ice machine error code may show as a number on a small display, a pattern of blinking lights on the control board, a colored light on the front, or a machine that stops with one indicator flashing. ### Make Monogram For a Monogram ice machine built into cabinetry, the technician plans access to the drain and water connections before pulling anything forward. ### Source Monogram UCC15NP clear-ice machine owner's manual (GE Appliances) — line printed in an encoded font, read as decoded Current Monogram 15-inch panel-ready machines: UNC15NP nugget (manual 49-1000610) and UCC15NP clear ice. The supply needs 30 to 120 psi. ## Before you book, in this order. Each step comes from Monogram's own guidance for Making Ice and Filter lights flashing alternately on its ice machines. Follow it to the end: the last card says whether this is a visit. 01 Open the shutoff valve that feeds the machine fully. 02 Follow the supply line behind the machine and straighten any kink, especially where the unit was pushed into its opening. 03 If the filter is near or past its change date, replace the GSWF cartridge behind the lower access door. 04 If the lights keep alternating with a good supply, book a visit to test the inlet valve. ### Still there?

Open the shutoff valve that feeds the machine fully. If it comes back, it needs a visit. ### My Monogram ice machine lights take turns flashing after a remodel. Why? The water supply was probably left closed or the line got kinked during the work. Open the valve fully and check the line behind the machine. ### Can a clogged filter cause the alternating lights on a Monogram? On the UCC15NP clear-ice model, Monogram lists the filter as a possible cause, so a filter past its change date is worth replacing. ### What water pressure should a Monogram ice machine get? Between 30 and 120 psi of cold potable water, according to the current manuals. --- **[Read on the site: Monogram Making Ice and Filter lights taking turns: low water supply](https://icemachinerepair.center/error-codes/monogram-making-ice-and-filter-flashing-alternately/)** **[Book a visit with IceMachineRepair.center](https://icemachinerepair.center/schedule/)**
