Bosch Refrigerator ice maker overflowing
If your Bosch refrigerator ice maker is overflowing or leaking water into the ice bin, start with the most likely causes: a faulty or stuck water inlet valve or insufficient house water pressure — the valve needs about 20 psi to shut off and will drip or run if pressure is low or the valve sticks open. Next check for obstructions or jammed food in the ice maker that can prevent normal cycling and cause overfilling. If neither of those is the problem, a failing ice maker assembly is often the culprit since many components are only sold as the full assembly. Less commonly, a bad auger motor or a jammed auger can back up ice and contribute to overflow, and broken mounting clips can let the ice maker sit out of position and leak. Inspect for visible jams, test water flow at the kitchen faucet, hand-turn the auger, and replace the inlet valve or ice maker assembly if needed.

01 - Bosch Refrigerator Water Inlet Valve
The water inlet valve requires a minimum of 20 psi to shut off properly. If the water pressure is too low, the valve may not close fully once the power is shut off. As a result, the valve will leak water into the ice maker and cause the ice maker to overflow. Check the water pressure to determine if it is at least 20 psi. If the water pressure is sufficient, the water inlet valve is likely defective. The valve may not shut off all the way or may be stuck open, causing water to leak through the valve. If the water pressure is sufficient, but the ice maker is still overflowing, replace the water inlet valve.

02 - Obstructed Ice Maker
If there are food items stuck in or jammed around the ice maker, it may not cycle properly. The ice maker may get stuck in the middle of a cycle or overflow with ice or water. Inspect the ice maker and remove any items that may interfere with its operation.

03 - Low Water Pressure from House Supply
The water inlet valve, which supplies water to the refrigerator ice and water dispenser, requires sufficient water pressure to work properly. If the water pressure is too low, the valve may not close fully when the power is shut off. As a result, the valve will leak water into the ice maker, causing it to overflow. You can check the water flow at the kitchen faucet to help determine if the home's water pressure is sufficient or not.

04 - Bosch Refrigerator Ice Maker Assembly
One component of the ice maker assembly might be defective. Since many of the ice maker components are not sold separately, you may need to purchase and replace the entire ice maker assembly.
Highly Likely
05 - Bosch Refrigerator Auger Motor
The auger motor spins the auger blade and pushes the ice through the dispenser chute. If the auger motor is burned out or defective, the ice won’t move forward and, potentially, the ice maker assembly can start to overflow. To determine if the auger motor is defective, pull out the ice bucket and turn the bucket auger by hand. If the auger turns freely, use a multimeter to test the auger motor for continuity. If the auger motor does not have continuity, or if the motor is getting power but won’t run, replace the auger motor.
Highly Likely
06 - Bosch Refrigerator Clip
Some refrigerator ice makers are secured with clips. If one or more of the clips break, the ice maker may become dislodged and start to overflow. If the ice maker assembly is not sitting flush against the wall, purchase a new clip or clips to secure and seal.
