--- title: "U-Line nugget ice machine with the NO WATER lamp blinking (Er15)" description: "What Er15 means on U-Line nugget ice machine with the NO WATER lamp blinking (Er15)s, what to check before booking, and when it is not a failure at all." url: "https://icemachinerepair.center/error-codes/u-line-er15/" --- # U-Line nugget ice machine with the NO WATER lamp blinking (Er15) The nugget machine fills a reservoir and a level sensor watches it. ## What Er15 actually means. The nugget machine fills a reservoir and a level sensor watches it. If the sensor sees no water for two minutes, the NO WATER lamp blinks and the event is recorded as Er15. The control tries again on its own after five minutes. U-Line ice machine display · also shown as NO WATER lamp blinking What to do when Er15 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 U-Line U-Line ice machine visits in a home bar start at the drain, since a slow line affects both the ice and the floor around it. ### Source U-Line URNP115 15-inch nugget ice machine user guide U-Line 1 Class RNP115 and Outdoor ONP115 nugget ice machines, which report through the ICE, NO WATER and DRAIN lamps beside the light button. ## Before you book, in this order. Each step comes from U-Line's own guidance for Er15 on its ice machines. Follow it to the end: the last card says whether this is a visit. 01 Open the machine's supply valve all the way and make sure the tubing behind the unit has no sharp bends. 02 Wait at least five minutes for the automatic retry once water is back. 03 If the lamp keeps blinking with good water pressure, book a visit to test the inlet and the level sensor. ### Still there? It usually turns into [ice machine water valve and filter repair](https://icemachinerepair.center/services/ice-machine-water-valve-and-filter-repair/). Book with the code and the model number. ### What not to do A steady NO WATER lamp simply reports low supply, while blinking means the two-minute limit was reached. When NO WATER blinks together with other lamps, it is a sensor or cooling pattern, not a water supply problem. ## What you may notice with it. The ice machine problems Er15 tends to arrive with.

Open the machine's supply valve all the way and make sure the tubing behind the unit has no sharp bends. If it comes back, it needs a visit. ### Does a U-Line nugget machine restart by itself after Er15? Yes, the manual says it resets after five minutes. It will stop again if the water still does not arrive. ### Can a shared water line cause Er15 on my U-Line? A line shared with another appliance, a clogged inline filter or a small saddle valve can starve the machine. Check the pressure where the machine connects. ### What does U-Line check for Er15 on a visit? Supply pressure and the water level sensor, then the machine is restarted. --- **[Read on the site: U-Line nugget ice machine with the NO WATER lamp blinking (Er15)](https://icemachinerepair.center/error-codes/u-line-er15/)** **[Book a visit with IceMachineRepair.center](https://icemachinerepair.center/schedule/)**
