# Why an Ice Maker Leaks Water, and Where It Is Coming From

## First: where exactly is the water

The answer to that question sorts this page into four very different repairs.

**In the bin, with the cubes fused into a block.** Water is arriving when it should not, or ice is thawing and refreezing.

**Under the drawer, as a sheet of ice, with normal ice in the bin.** Melt water that could not leave the cabinet. That is the drain, not the ice maker.

**At the front, on the floor.** Either of the above, once there is enough of it — or the door seal.

**Around the filter housing.** A cartridge not fully seated. Ten seconds to check and it happens more than people expect.

## The four sources

### 1. A fill valve that seeps

The valve lets a measured amount of water into the mold and closes. One that no longer seals fully drips between cycles, and what it drips freezes onto the last batch. The tell is ice that grows into a solid lump rather than staying as cubes.

This is a part rather than a setting, and it is the cheaper end of an ice-maker repair.

### 2. A frozen fill tube

The tube that carries water to the mold sits in a cold place by definition. If a fill is slow — low pressure, a restricted filter — water lingers in it and freezes. The next fill arrives, meets ice, and goes everywhere except into the mold.

Thawing it clears it once. If it returns, the reason the fill was slow is the actual problem, and that is usually [pressure or a filter](/blog/thermador-water-filter-and-reset/).

### 3. A blocked defrost drain

Nothing to do with the ice maker. Melt water from the evaporator cannot leave, so it pools and refreezes under the drawer. Clearing it is [a ten-minute job](/blog/cleaning-a-refrigerator-drain-line/) with warm water and soft tubing.

### 4. A cabinet running a few degrees warm

This one produces several symptoms at once: soft ice, ice fusing, and more melt water than the drain was designed for. If the ice is poor **and** there is water, look at the column rather than at the ice maker. [How a warm cabinet is worked through](/symptoms/refrigerator-not-cooling/).

## The thing that makes all of it worse

**A column that is not level.** Water sits where it should run, the door does not close squarely, and melt water finds the front instead of the drain. On built-in equipment leveling is an installation question rather than an afternoon one, but it is worth knowing that it can be the cause rather than a detail.

## What to check before calling

- Is the filter fully rotated home, with the marks aligned?- Is the water pressure at the dispenser normal?- Is the ice **poor** as well as wet — small, hollow, or slow?- Where exactly is the water: bin, under the drawer, or the floor?- Has anything changed — a filter, a defrost, a power cut?

Those five answers tell us which of the four sources above we are coming for, and that decides what we bring. [What the repair involves](/services/ice-maker-and-water-repair/) and what it starts at.
