# Frigidaire ice machine descaling

### Soft, cloudy, slow: the water is the diagnosis

A countertop machine that has become slow and noisy is usually not failing mechanically. South Florida water leaves scale on the evaporator fingers, and scale is an insulator: the cycle lengthens, the cubes come out cloudy and soft because they never fully hardened, and the pump works against a restriction it did not have when it was new. Descaling is the whole repair in most of these cases, and where it is not, a machine that has just been descaled is far easier to diagnose than one that has not.

What this involves

The commonest cause of slow, soft or cloudy ice on a countertop machine

The maker's own routine, not a household improvisation

Twice a year in this water is the honest interval

Empty and inspect the reservoir

Scale, biofilm and whatever the tap has left. What is in there explains the ice that came out of it.

Run the descaling routine

Solution through the pump and over the fingers for the full dwell, not a rinse.

Clean the pump inlet and the fingers by hand

The parts the solution cannot reach are the ones holding the deposit.

Rinse until the water runs clean

Two or three full cycles discarded. Ice that tastes of the cleaner is a job half done.

Make a batch and check it

Cycle time and cube clarity measured against what the machine should do.

### How often should a countertop machine be descaled here?

Every few months if it runs daily on tap water, and that is not a maker's schedule so much as a local one. Filtered or bottled water in the reservoir stretches it considerably.

### Can I use vinegar instead of a descaling solution?

For a light film it works and it is what most people have. Where scale has built for a year vinegar will not shift it in one pass, and repeated soaking is harder on the pump seals than one proper descale.
