The Water light is one of four lights on the Prodigy front panel. It blinks red when the reservoir does not fill in time. The code display has its own entry for the same slow fill, 3, and a cuber keeps trying to fill every 20 minutes until water returns. Scotsman ice machine display What to do when Water light blinking red 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 Scotsman A Scotsman visit sorts out which kind of ice the machine makes, because each kind follows a different service path. ### Source Scotsman Prodigy ELITE modular cuber service manual, MC0322 through MC2148 (January 2022) Prodigy and Prodigy ELITE cubers (MC and C models) show one character in the code display next to the lights. Prodigy flaked and nugget machines with the CM3 control (N and F models) use the same display with a different code list. ## Before you book, in this order. Each step comes from Scotsman's own guidance for Water light blinking red on its ice machines. Follow it to the end: the last card says whether this is a visit. 01 Check that the water supply valve is open and the filter is not blocked. 02 Look for a kinked supply line behind the machine. 03 If the light keeps blinking with water on, book a visit for the inlet valve. ### Still there?

Check that the water supply valve is open and the filter is not blocked. If it comes back, it needs a visit. ### My Scotsman water light is red but water is on. What else? A clogged filter or a failing inlet valve can starve the fill even with the valve open. ### Is the red water light related to code 3 on a Scotsman? Yes. Both report a slow fill. ### Can a leak make the Scotsman water light turn red? No. The light reports water not reaching the reservoir, not water escaping. For water on the floor, close the supply valve. --- **[Read on the site: Scotsman water light blinking red: the reservoir did not fill](https://icemachinerepair.center/error-codes/scotsman-water-light/)** **[Book a visit with IceMachineRepair.center](https://icemachinerepair.center/schedule/)**
