What E27
actually means.

True uses the sump level to time its harvest. If the level drops that far that early, water is escaping the loop, and True's checklist is splashing past the water curtain or the bin flap, or a drain valve that leaks.

What to do when E27 shows on the ice machine

Kind 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 E27 on its ice machines. Follow it to the end: the last card says whether this is a visit.

01

Turn the head off and check that the water curtain is seated and hanging freely.

02

Look at the bin and harvest flap area for water streaming into the bin.

03

If the curtain and flap are fine, book a visit to check the drain valve for leaks.

It usually turns into ice machine water valve and filter repair. Book with the code and the model number.

What not to do

E27 is water loss during freezing, not a leak onto the floor; if water is spreading on the floor near power, shut the water off and treat it as urgent. It also differs from E23, a level calculation alarm technicians read in the log.

Questions
about E27.

Can I clear E27 myself?
Turn the head off and check that the water curtain is seated and hanging freely. If it comes back, it needs a visit.
Can a water curtain put back wrong cause E27 on a True?
Yes. After cleaning, a curtain that is not seated lets water splash into the bin, and the sump level falls early.
Is E27 the same as my True leaking on the floor?
No. E27 means water is leaving the sump, usually into the bin or down the drain. A puddle under the head is a separate problem to report.
Why are my cubes small when E27 shows up?
Water that leaves the loop is not frozen, so sheets come out thin. Fixing the splash or the leak brings the cube size back.

Back to your everyday

Still showing E27?

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.
