What E24
actually means.
Each cycle, a True head fills its sump before freezing. E24 means that fill stalled for half an hour, and True's list of causes is short: no water, a clogged incoming water filter or an inlet valve that is not opening.

What to do when E24 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.

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 E24 on its ice machines. Follow it to the end: the last card says whether this is a visit.
Make sure the water supply valve to the head is fully open.
Check the water filter cartridge and replace it if it is past its capacity or the outlet pressure is low.
If water is on and the filter is new, book a visit to test the inlet valve.

What not to do
E24 is the half-hour timeout; a fill that misses its first three minutes shows as E29, shown on screen as H₂O. It is not a drain problem; a sump that will not empty is E25.

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.
