Bosch Refrigerator Water Dispenser Not Working – How to Fix

Troubleshoot the following components if you notice your Bosch water dispenser is not working:

1. Dispenser Control Board

Most parts of the dispenser are controlled by the dispenser control board. Refrigerator manufacturers advise that you troubleshoot all other components of your dispenser before troubleshooting the dispenser control board. If the control board is faulty, go for a replacement.

2. Dispenser Switch

With the dispenser switch, the voltage can be transmitted to the dispenser. The Bosch dispenser system will not work if just one of its switches is defective.

To know whether a dispenser switch is defective or not, test it with a multimeter for the presence of continuity. If the dispenser switch lacks continuity, get a new one.

3. Door Switch

Once the refrigerator door is opened, the dispenser turn off. If this mode of operation is altered, that is an indication that the door switch is defective. Just like the dispenser switch, you need to carry out a continuity test to ascertain the working condition of the door switch. The reading of the test should inform you on whether to go for a new door switch or not.

4. Water Filter

Another component to troubleshoot if your water filter is not working is the water filter. It ensures that the water you get to drink from the dispenser is clean and clear.

If you do not replace the water filter at least once in six months, it will get clogged and that may prevent the flow of water to the dispenser.

5. Water Inlet Valve

When the dispenser switch is pressed, the water inlet valve sends water to the dispenser. If the valve is broken and cannot send water at a pressure of 20 PSI, it may be the reason why your Bosch water dispenser is not working. Conduct a continuity test and replace the water inlet valve if no continuity is detected.

Now, let’s deal with another Bosch refrigerator dispenser problem.

Bosch Refrigerator Water Dispenser Leaking – What to Do

The different parts of your Bosch refrigerator water dispenser need to be troubleshot to get to the bottom of the leaking issue. Here is how to go about the troubleshooting of the components

1. Clogged Defrost Drain

In the event of a frozen defrost drain, the water in the dispenser will fill the drain trough and escape to the bottom compartment. After a few minutes, the water will leak onto the ground and you will start noticing it.

To troubleshoot and fix the defrost drain, check if it is frozen and if it is, melt the ice. Also, clear the drain with a bowl of hot water and that should do the trick.

2. Water Tank Assembly

Apart from the defrost drain, inspect the water tank assembly of your Bosch water dispenser to know if there are any leaks. The leaks in the water tank assembly are quite minute and unnoticeable, so you have to observe them very carefully before you can find them.

If you find the leaking part, get a new water tank, instead of repairing the old one. This is because water tanks are made of plastics and so they cannot be glued back together..

3. Water Filter Housing

Another component that perhaps is responsible for leaks is the water filter housing. If it is cracked, get a new one and your Bosch refrigerator water dispenser leaking problem will be a thing of the past.

4. Water Filter Head

If the water filter head is cracked, torn or misplaced, your Bosch refrigerator water dispenser will start leaking. So check for the aforementioned defects and replace the water filter head if you notice it is defective.

5. Drain Pan

As a self-defrosting appliance, the Bosch refrigerator water dispenser has a drain pan that holds the water, which thaws from the dispenser evaporator coils. The condenser fan circulates hot air to the drain pan for evaporation to take place.

Since evaporation takes place because of the condenser fan, the drain pan should not be empty. So, if you notice the drain pan is empty, that is an indication of a crack somewhere and calls for a replacement.

6. Water Filter

If you have troubleshot all other components and you still cannot find the issue, then the water filter is most likely the culprit. If it is not tightened properly, water may leak. So, simply tighten the water filter and your leaking problem will be gone.

7. Water Inlet Valve

This component of the Bosch refrigerator water dispenser is put in place for supplying the dispenser with the needed amount of water. Perhaps the reason for your dispenser leaking is because the water inlet valve is broken or loosely fitted.

Check the water inlet valve for any sign of cracks or loose-fitting, and fix it by simply following the guidelines in the user’s manual.

Bosch Refrigerator Water Dispenser Light Not Working – How to Solve It

Apart from leaking and locking problems, your Bosch water dispenser may also have lighting problems. Here are the different components to troubleshoot so as to fix the lighting problem:

1. Lamp

If your Bosch refrigerator water dispenser is not working, start your troubleshooting process with the lamp or light bulb. Conduct a continuity test to know if the filament is broken and needs replacement.

To test the lamp using a multimeter, start by removing the bulb from the dispenser. Next, position the multimeter on Rx1 setting and then put one terminal on the bottom of the bulb, and another at the threading. If the multimeter shows an infinite reading, you have to replace the light bulb.

2. Light Sockets

After troubleshooting and discovering that the light bulb is working properly, move on to the light socket. Start troubleshooting the light socket by unplugging it for your own safety. Check if any terminal is damaged or discolored. If either is the case, replace the light socket.

3. Door Light Switch

As the door of the water dispenser is opened, the light goes OFF and toggles ON again once it is closed. But then, if the door light switch is defective, the light will remain ON even when the dispenser door is closed.

To test whether the door light switch of your Bosch refrigerator water dispenser is defective or not, turn OFF the dispenser and situate the door light switch and remove it.

Now, the multimeter settings should be at Rx1 to allow for a continuity test. After that, the door switch terminals should be on the probes, so you can check the readings.

If the multimeter reading moves from infinity to zero and from zero to infinity, then the door light switch is working properly. However, if that is not the case, the door light switch is due for replacement.

4. Light Bulb & Ice Dispenser

If your model of Bosch refrigerator water dispenser comes with a light bulb and ice dispenser, check if they are working properly. The light bulbs are supposed to be on low wattage, which makes them unsuitable for any other purpose safe refrigerator lighting.

If you open the dispenser for an extended period of time, the light bulb and ice dispenser may get damaged. To know the working condition of these components, use a multimeter to test for continuity.

But before that, ensure that the dispenser is unplugged from its source of power. After that, go to the control panel and take off its cover to gain access to the light switch.

Now, you can conveniently test for continuity by probing both terminals of the light switch. If the reading indicates that there is no continuity, you have to replace the switch.

What to Do If My Bosch Refrigerator Water Dispenser is Slow?

If your Bosch refrigerator water dispenser had low pressure, dispensing water will be slow. Here are some actionable ways to make your water dispenser pressure higher:

1. Check the Water Filter Installation

To start with, you are supposed to replace the water filter of your dispenser at least twice a year. If you do not, the water filter may be clogged with dirt or with micro mineral accumulation. When that happens, the dispensing rate of your appliance will drop.

First of all, check the user manual of your Bosch refrigerator water dispenser to see how you can replace the water filter for that particular version.

That said, you can compare the present flow rate of the water filter and the original flow rate when you initially bought the dispenser. If you notice a decrease flow rate, it means the water filter is clogged or improperly fixed. Do the needful and your Bosch refrigerator water dispenser will be good as new.

2. Inspect the Water Supply Line

The water supply line of your dispenser is meant to link the water dispenser and the water source together. However, water will not flow from the source to the dispenser if the supply line is pinched or kinked. Consequently, the dispenser pressure will be low.

To remediate this, straighten the kinked section of the water supply line. The water supply line tends to be pinched when you position your dispenser very close to the wall.

3. Reverse-Osmosis Filtration System

If you installed a reverse-osmosis filtration system on your dispenser, the pressure will be reduced. To correct the problem, you have to install a water supply line that is separate from the reverse-osmosis system. If that does not work, you may have to take off the water filter of the dispenser.

4. Dispenser Not Evenly Leveled

If your dispenser is not leveled, the water pressure will be affected. Peruse the dispenser user manual to know the appropriate way to level the appliance because different models have different leveling techniques.
