What E31
actually means.
In harvest, a True head opens a hot gas valve to warm the evaporator. If high-side pressure keeps rising past 165 psi instead, the control suspects the valve and sends technicians to its no-harvest, frozen-in flow chart.

What to do when E31 shows on the ice machineKind of codeHarvest and freeze cycle
A freeze ran longer than the board allows, or a harvest started and the ice never fell. Scale on the evaporator holds the sheet to the plate, a thickness probe crusted with minerals never signals, a hot gas valve that does not open leaves the plate cold, a harvest assist that does not push, or a water curtain that swings without tripping its switch all end in this family. A cleaning cycle run by the manual often clears it; a valve or a probe is a technician's job.

The hot gas valve, harvest assist, curtain switch and thickness probe that decide when a sheet of cubes is done and make it drop.

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 E31 on its ice machines. Follow it to the end: the last card says whether this is a visit.
Turn the head off and check whether ice is frozen onto the evaporator.
Let any stuck ice melt on its own rather than forcing it off.
Book a visit; the hot gas valve and harvest pressures are tested with gauges on a flammable R-290 system.

What not to do
E31 is about the hot gas valve during harvest, while E26 is a harvest that ran long for any reason. Neither is a water alarm, even though a frozen-in evaporator can look like one.

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.
