What E30
actually means.
Heads fitted with TrueZone carry a UV lamp with its own status screen. E30 tells you the control saw low current, high current or a lamp that has passed its run time; the UV information screen in the menu says which.

What to do when E30 shows on the ice machineKind of codeControl board and power
The board lost track of itself or of its power: a voltage too low or too high at startup, a relay that no longer closes, a keypad or display that stays dark, or a memory error after a surge. Switching off at the machine's own switch for a minute clears a passing glitch. A code that returns, a breaker that trips, or any hot or burning smell means the power stays off and the board, the wiring and the relays are left to a technician.

The controller, its display, the sensors it reads and their wiring, tested when a code, a blinking light or a dead machine points there.
Shows up asIce 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.

True ice machine visits begin with the installation: the supply, the drain fall and the clearance the machine needs to cool.

Before you book,
in this order.
Each step comes from True Residential's own guidance for E30 on its ice machines. Follow it to the end: the last card says whether this is a visit.
Open the UV information screen in the menu and note whether it shows low current, high current or lamp time exceeded.
If it shows lamp time exceeded, plan a bulb replacement per True's procedure.
Book a visit for a current problem; the lamp circuit is checked with power isolated, and UV light should never be looked at directly.

What not to do
E30 is not a sign that ice is unsafe on its own; the ice machine keeps its normal cleaning schedule either way. Heads without TrueZone do not raise it.

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.
