What E25
actually means.

Between cycles a True head purges part of the sump water to carry away minerals. E25 means the water did not leave fast enough, and True's checks are the drain valve coil, a clogged or unvented drain and a blocked sump drain.

What to do when E25 shows on the ice machine

Before you book,
in this order.

Each step comes from True Residential's own guidance for E25 on its ice machines. Follow it to the end: the last card says whether this is a visit.

01

Check the drain line from the head for kinks, and the floor drain or air gap for backup.

02

Make sure the drain line is vented as installed.

03

Book a visit if the drain is clear; the drain valve coil needs a voltage check.

Still there?

It usually turns into ice machine drain and pump repair. Book with the code and the model number.

What not to do

E25 is about water leaving the sump, not about the bin drain, which is a separate line. It is also not a fill problem; slow filling is E24 or E29.

Where E25 usually leads

Ice machine drain and pump repair.

Drain line clearing, air gap, drain pump, float and check valve · low to moderate.

Questions
about E25.

Can I clear E25 myself?
Check the drain line from the head for kinks, and the floor drain or air gap for backup. If it comes back, it needs a visit.
Can a clogged floor drain cause E25 on a True ice machine?
Yes. If the head's drain water cannot get away, the sump drains slowly and the alarm is logged.
Why does True care whether the drain is vented?
An unvented line can hold an air lock that slows draining. True lists venting among its E25 checks.
Does hard water make E25 more likely?
Scale in the sump drain and valve can slow the purge. The water hardness setting also changes how long the purge runs.

Back to your everyday

Still showing 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.
