Bosch Ice Maker Not Working — How to Fix

What Does This Error Mean?

The most common reason a Bosch ice maker stops working is the water supply — check that the shut-off valve behind the fridge is fully open and that the water supply line is not kinked. Also check that the ice maker is switched on (there is usually an on/off switch on the ice maker module or in the fridge control panel) and that the ice bucket is not full (the arm or sensor pauses production when the bucket is full). For error code E30, see the E30 page.

Affected Models

Bosch French Door Refrigerator
Bosch Series 6 American-Style Fridge
Bosch Series 8 American-Style Fridge
Bosch KGF Series
Bosch KAD Series

Common Causes

Water supply shut-off valve not fully open or water supply line kinked behind the fridge
Ice maker switched off in the control panel or on the module itself
Ice bucket full — the arm or optical sensor has paused production until ice is used
Water filter clogged — flow rate too low for the ice maker to function
Ice maker module internal fault — requires a reset or replacement

How to Fix It

Check the ice maker is switched on

On the fridge control panel, confirm the ice maker function is enabled. On some models, there is a physical on/off switch on the ice maker module itself — check it has not been accidentally switched off.
Check the water supply valve

Pull the fridge out and locate the water supply line at the back. Follow it to the wall where it connects to a shut-off valve. The valve must be fully open (parallel to the pipe, not perpendicular). Confirm the supply line is not kinked.
Check the ice bucket

Remove the ice bucket and empty it. The ice maker pauses production when the bucket is full. Some models use a bail arm that rises when ice reaches the top — check the arm is in the down (on) position.
Replace the water filter

A clogged water filter reduces flow below the minimum needed to fill the ice maker tray. Replace the filter (typically every 6 months). After replacing, run the ice maker for 24 hours before expecting production to normalise.
Reset the ice maker

Switch the ice maker off at the control panel, wait 30 seconds, then switch it back on. Alternatively, press and hold the reset button on the ice maker module for 3 seconds. Allow 24 hours for the first batch of ice to be produced.

When to Call a Professional

If the water supply is confirmed and the ice maker is switched on but still produces no ice after a 24-hour reset, the water inlet valve solenoid has failed. A Bosch technician can test the valve and replace it.

Frequently Asked Questions

Bosch ice maker makes ice but it clumps together — why?

Clumping means ice is melting slightly and refreezing together — usually because the freezer temperature is not low enough. Set the freezer to -18°C and ensure the ice bucket is not near the back wall where it can be warmed by the defrost heater.

Bosch ice maker stopped working after a power cut — why?

A power cut can reset the ice maker module to its off state on some models. Check the ice maker switch in the control panel. Also confirm the water supply valve is still open if the fridge was moved during the outage.

Bosch ice maker is making a noise but not producing ice — why?

If the mechanism is running but no ice is being produced, water is not reaching the tray. The water inlet valve solenoid that controls flow into the ice maker has likely failed. This is confirmed if the water dispenser (if fitted) also has reduced or no flow.
