What Er25
actually means.
Viking ties Er25 mainly to a cold room. When the evaporator outlet stays below its set point for 2 minutes during icemaking, the control stops and lights every lamp, and Viking asks for the machine to run only where the room is above 50°F.

What to do when Er25 shows on the ice machineKind of codeCooling system
The board saw temperatures or pressures that the sealed system should never reach: a discharge line too hot, a suction side that never cools, or a compressor that starts and stops on its overload. A dirty condenser can push a healthy system into this family, so it is the first thing to rule out; a low charge, a leak or a tired compressor is not. On many current machines that system holds R-290, which is flammable, and only a technician opens it.

The compressor, its start parts and the sealed system, including machines on flammable R-290, tested for pressure and leaks and repaired by the maker's procedure.

in this order.

Warm the space above 50°F, then turn the machine off and on.
If Er25 returns in a warm room, book a visit.

What not to do
Three steady lamps are not Er01, where the same three lamps blink because the evaporator is too warm. It is also not a sign of low refrigerant on its own.
