# Bosch ice maker not making ice

### The fastest diagnosis is the code

This is one of only three things Bosch refrigeration publishes a code for, so if there is one on the display it is worth reading. Most of the time there is not, and the useful information is whether it slowed down or stopped.

### Slow comes before stopped

An ice maker almost never fails overnight. A full bin becomes a half bin over several weeks, and by the time it is empty the cause has been there a while. Every one of the cheap causes — filter, air, pressure — is easier to fix and cheaper to diagnose while the machine is still working badly rather than not at all.

### The fast ice makers

The upper series produce a great deal of ice quickly, which means they ask more of everything upstream of them and they are a more expensive assembly to replace. Both are arguments for diagnosing this properly instead of ordering a module.

The water filter

Past its life, the wrong one for the model, or not seated. If it stopped right after a filter change, this is almost certainly it.

Air in the line

After a filter change. Draw several liters off at the dispenser to clear it — free, and it fixes a surprising number.

Supply pressure or a pinched line

A line crushed when the refrigerator was pushed back, or genuinely low pressure in an older building.

A freezer running warm

An ice maker in a compartment two degrees warm behaves exactly like a broken one. Worth checking before any part is discussed.

The ice maker module

Harvest motor, mold heater or the sensor. The fast ice makers on the upper series are a more expensive assembly and worth diagnosing rather than swapping.

Check the filter date

And that it is genuinely the right cartridge for the model. Aftermarket filters that "fit" are behind a lot of these calls.

Run several liters through the dispenser

If water flows freely, supply is fine and the problem is downstream. If it dribbles, you have found it.

Put a thermometer in the freezer

Overnight. A compartment that is not cold enough will not release ice from the mold however healthy the module is.

Check the arm or the switch

Many units have a shut-off arm or a control that turns the ice maker off, and both get knocked by accident when the bin is pulled out.

Slow before it stops

What it usually means

Half the ice it used to make

Stopped completely after a filter change

Ice tastes or smells wrong
