If you’ve found your Bosch refrigerator dispenser not working, you’re likely scratching your head, wondering where to start troubleshooting. This issue is pretty common with fridges and so we’re here to help guide you through the process of getting it working again.
Why Is My Bosch Refrigerator Dispenser Not Working?
This handy guide will take you through common problems that can leave you with a Bosch refrigerator dispenser not working properly. From simple fixes to more complicated issues, we’ve got you covered.
Is Your Dispenser Control Locked?
Why did my refrigerator water dispenser suddenly stop working? The first thing you’ll want to check when your Bosch refrigerator dispenser is not working is the dispenser control lock. This feature, often denoted by a lock symbol, is designed to prevent accidental dispensing. If the control is locked, neither ice nor water will be dispensed.
- To unlock, simply press and hold a “lock” button (or another designated combination of buttons) for around 5 to 10 seconds.

Bosch Water Filter Replacement
If you’re Bosch water dispenser is not working after replacing the filter, this may be your problem. A clogged water filter or a misaligned filter can often be the reason behind a malfunctioning dispenser, it can also cause refrigerator leaks. If your water or ice tastes off, or the dispenser works intermittently, it might be time to replace the filter.
Bosch recommends replacing your Bosch refrigerator water filter every six months or after 200-300 gallons of water have been dispensed to maintain optimal performance. A misaligned filter may also cause a problem, so remove and reinstall it to ensure proper seating.
Checking the Water Inlet Valve and House Supply Pressure
The Bosch refrigerator water inlet valve is a vital part that opens to supply water to the dispenser. It requires at least 20 psi to function correctly. Low house supply pressure or a defective valve could result in the Bosch refrigerator dispenser not working.
- Confirm the water pressure is at least 20 psi.
- If it is, a technician can use a multimeter to check the water inlet valve for continuity. If it doesn’t show continuity, it might be time to replace it.
Look Out For Frozen Water Lines
If you’ve noticed your Bosch refrigerator water dispenser is slow, working intermittently, or not at all, you might be dealing with a frozen water line. You may also notice noises from your fridge if your water line is frozen.
- Disconnect the tube at the bottom of the door and blow air through it.
- If air does not pass, the water supply tube might be frozen.
- Thaw it out and ensure your freezer temperature is kept between 0-10 degrees Fahrenheit to prevent freezing in the future.
Check the Door Switch and Dispenser Switch
The door switch is crucial for dispenser functionality. When the refrigerator door is open, this switch prevents the ice maker and water dispenser from operating. Make sure the refrigerator door is closing fully first. If it is, check the door switch to see if it’s defective, a tech can use a multimeter to test it for continuity. Lack of continuity signals that it needs to be replaced.
Similarly, the dispenser switch plays a crucial role. It activates the dispenser when needed. If this switch fails, you’ll find your Bosch refrigerator dispenser not working. A technician can test the dispenser switch with a multimeter. If there is no continuity, it will need to be replaced.

Time to Call in the Pros
While DIY solutions can often fix the problem, there are times when you need a professional hand. For example, if you suspect a problem with the dispenser control board or the main control board of the refrigerator, it’s better to seek professional help. These parts control the majority of the dispenser’s functions and can be tricky to handle if you’re not a trained technician.
