If your Bosch ice maker isn’t working, there could be several possible causes. Check the water supply, inlet valve, and water filter. Make sure the freezer temperature is set correctly, and inspect the ice maker itself for any damage or blockages. If you’re not comfortable with DIY repairs, it’s best to call a professional.

Why Is Your Bosch Ice Maker Not Working?

Different reasons can lead to your Bosch ice maker not working. For example, the freezer’s temperature is too high, or the water inlet valve of the refrigerator has an issue.

1- The Freezer Temperature Is Too High

The freezer’s temperature plays a vital role in forming your ice. The freezing point of water is below 32 degrees Fahrenheit (0 Celsius); however, it’s advised that you keep the freezer temperature at a degree colder than that.

The colder your freezer, the more efficient is your ice maker; the recommended temperature is between 5 to 0 degrees Fahrenheit.

2- Faulty Water Inlet Valve

Your water dispenser and ice maker need a water supply to function; the water inlet valve is the one responsible for this water supply.

The refrigerator’s valve provides water from your household’s water to your ice maker. Therefore, the ice maker will receive no water if your water inlet valve is faulty.

The refrigerator’s valve provides water from your household’s water to your ice maker. Therefore, the ice maker will receive no water if your water inlet valve is faulty.

You should notice that the valve could be working correctly, but the issue is in the water pressure of your household. The inlet valve will stop working if your household has insufficient water pressure.

3- Broken Ice Maker Thermostat

Icemakers’ thermostat is essential because it detects when the ice tray temperature is suitable. Then, the ice maker exports the ice cubes to the tray and get resupplied with water.

Therefore, if the thermostat of the ice maker is broken, the ice maker will no longer detect when to eject the ice cubes.

You can determine if your thermostat is broken by using a multimeter. Switch for continuity on the multimeter’s settings and check the thermostat. If the thermostat has continuity, then it’s working correctly.

4- Faulty Ice Maker Assembly

The ice maker assembly consists of several parts; there might be an issue with one of them. Unfortunately, ice maker assembly parts are rare in local hardware stores.

As a result, if the issue is with one of the assembly parts, you will need to replace the whole unit. Don’t worry; your ice maker assembly rarely fails; you should check other components before you consider that problem is with the assembly.

5- Door Switch Not Working

The door switch is inside the freezer, mainly on the right side. You can think of the door switch as an alarm that lets the fridge shut down when the ice maker is on.

The freezer door switch is triggered when you open the freezer door. As discussed above, the freezer’s high temperature affects the ice maker.

When you open, the door of the freezer temperature starts to increase, so the ice maker should be turned off. If your door switch fails, this will result in either the ice maker stopping working or working all the time.

6- Ice Maker Switch Toggled Off

The ice maker has a switch that controls whether it’s working. Like any other switch, it has an “ON” and “OFF” position. You could have mistakenly switched the ice maker off without knowing.

Therefore, you will need to check the switch to see if it’s in the “ON” position, it may seem a bit obvious, but it’s better to check first before saying that the switch is faulty.

If the switch is in the “ON” position, you will need to check it using a multimeter to know if it has continuity. You will need to replace the switch with no electrical continuity.

7- Clogged Water Filter

As we have discussed, the refrigerator is supplied with water from your household’s water supply. Therefore, there will be a water filter in your refrigerator.

The water filter’s job is to filter the water from debris or harmful things. For example, the water filter removes lead, chlorine, and mineral deposits to improve water quality.

The water filter can get clogged with constant filtration, resulting in rare or no water passing through. As a result, the ice maker will no longer receive any water, and it will stop working.

8- Broken Ice Dispenser

The ice maker and ice dispenser work harmoniously; if one fails, the other will stop working. The ice dispenser is responsible for delivering your ice.

So the ice maker might be working correctly and forming ice, but you’re receiving none because of the dispenser.
