What Er15
actually means.
The water level sensor in the reservoir expects to see water shortly after the inlet opens. When it sees none for 2 minutes, the control stops and blinks the No Water lamp; Viking's table names this Er15 and points first at supply pressure, then at the level sensor itself.

What to do when Er15 shows on the ice machineKind of codeWater 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.

Before you book,
in this order.
Each step comes from Viking's own guidance for Er15 on its ice machines. Follow it to the end: the last card says whether this is a visit.
Open the shutoff valve feeding the machine fully and check the supply line for kinks behind the cabinet.
If the house recently had the water off, run a nearby tap until it flows clear, then switch the machine off and on at its mode switch.
If the No Water lamp blinks again with good pressure, book a visit to test the water level sensor and inlet valve.

What not to do
Er15 is not the drain condition, which blinks the Drain lamp instead. It is also different from the steady No Water lamp in the control guide, which simply reports a low supply while the machine keeps trying.

A booking with a code goes further when it carries the light or code copied as it appeared, the model and serial off the data plate, and a word on whether cubes still fall into the bin. With those three in hand, our office can match the probable part to your machine the same afternoon.
