What Does Water Tap Mean on a Bosch Dishwasher?
The “Water Tap” error message on a Bosch dishwasher indicates a problem with the water supply to the appliance. It essentially means the dishwasher isn’t receiving enough water to operate correctly, preventing it from starting or completing its cycle. The issue could stem from various factors, ranging from a simple closed valve to a more complex problem with the water inlet valve itself.
Understanding the Water Tap Error: A Comprehensive Guide
Bosch dishwashers, renowned for their efficiency and reliability, incorporate sophisticated error detection systems. The “Water Tap” error is a common indicator that something is amiss with the water intake process. Understanding the potential causes and troubleshooting steps is crucial for resolving the issue quickly and efficiently.
Potential Causes of the Water Tap Error
The “Water Tap” error on a Bosch dishwasher can arise from several sources. Pinpointing the exact cause is the first step toward a successful resolution. Here are some of the most common culprits:
- Closed Water Supply Valve: This is the most frequent reason for the error. The valve that supplies water to the dishwasher may be accidentally closed or only partially open.
- Kinked or Blocked Water Inlet Hose: The hose connecting the water supply to the dishwasher could be kinked, twisted, or blocked by debris, restricting water flow.
- Clogged Water Inlet Valve Filter: The inlet valve typically has a filter to prevent debris from entering the dishwasher. Over time, this filter can become clogged, hindering water intake.
- Faulty Water Inlet Valve: The water inlet valve itself may be malfunctioning, preventing water from entering the dishwasher even when the supply is open.
- Low Water Pressure: Insufficient water pressure in your home can trigger the error.
- Malfunctioning Flow Meter: The flow meter measures the amount of water entering the dishwasher. If faulty, it might send incorrect signals to the control panel.
- Control Board Issues: In rare cases, a problem with the dishwasher’s control board can cause the “Water Tap” error.
Troubleshooting Steps: A DIY Approach
Before calling a repair technician, you can try these troubleshooting steps to resolve the “Water Tap” error:
Check the Water Supply Valve: Ensure the water supply valve is fully open.
Inspect the Water Inlet Hose: Look for kinks, twists, or obstructions in the hose. Straighten any kinks and remove any visible debris.
Clean the Water Inlet Valve Filter:
- Turn off the water supply valve.
- Disconnect the water inlet hose from the dishwasher.
- Locate and remove the filter (usually a small screen).
- Clean the filter thoroughly with a brush and water.
- Reinstall the filter and reconnect the hose.
Check Water Pressure: Test the water pressure in your home. Ideally, it should be within the range specified in your dishwasher’s manual.
Restart the Dishwasher: After completing the above steps, try restarting the dishwasher to see if the error clears.
When to Call a Professional
If you have tried the troubleshooting steps above and the “Water Tap” error persists, it’s time to consult a qualified appliance repair technician. Potential problems that require professional attention include:
- Faulty Water Inlet Valve: Replacing a faulty inlet valve requires technical expertise.
- Malfunctioning Flow Meter: Diagnosing and replacing a faulty flow meter is best left to a professional.
- Control Board Issues: Control board repairs can be complex and require specialized knowledge.
- Persistent Low Water Pressure: A plumber may need to address underlying plumbing issues causing low water pressure.
Preventive Measures
Taking preventive measures can help minimize the risk of encountering the “Water Tap” error:
- Regularly Check Water Supply: Periodically check the water supply valve and hose for any issues.
- Clean Inlet Valve Filter: Clean the water inlet valve filter at least once a year.
- Monitor Water Pressure: Be aware of any fluctuations in your home’s water pressure.
- Use a Water Softener (if needed): Hard water can lead to mineral buildup, which can affect the dishwasher’s components.

Frequently Asked Questions (FAQs)
What happens if I ignore the “Water Tap” error?
Ignoring the “Water Tap” error can lead to several consequences. The dishwasher will not run, and attempting to force it can potentially damage the appliance. Prolonged water deprivation can also affect other components and shorten the dishwasher’s lifespan.
Can I use the dishwasher with the “Water Tap” error showing?
No, you should not use the dishwasher with the “Water Tap” error displayed. The dishwasher is designed to operate with a specific amount of water, and running it without sufficient water can cause damage to the heating element and other parts.
Is the “Water Tap” error the same as a low water pressure warning?
While low water pressure can cause the “Water Tap” error, they are not exactly the same. The “Water Tap” error is a broader indication that the dishwasher isn’t receiving enough water, regardless of the specific cause. Low water pressure is just one potential cause.
How often should I clean the water inlet valve filter?
It’s recommended to clean the water inlet valve filter at least once a year. However, if you have hard water or experience frequent clogs, you may need to clean it more often.
What tools do I need to clean the water inlet valve filter?
You typically only need a few basic tools:
- A small bucket or container
- A small brush (like an old toothbrush)
- Pliers (optional, if the filter is difficult to remove)
Can a faulty water inlet valve cause other problems?
Yes, a faulty water inlet valve can potentially lead to other issues, such as:
- Leaking: A faulty valve may leak, causing water damage.
- Overfilling: In some cases, a malfunctioning valve can cause the dishwasher to overfill.
- Incomplete cycles: The dishwasher might not complete cycles because it cannot get enough water.
How do I know if my home has low water pressure?
You can check your home’s water pressure using a water pressure gauge, which can be attached to an outdoor faucet. Consult your dishwasher’s manual for the recommended water pressure range. Also, slow-filling sinks or showers can be signs of low pressure.
What is a flow meter, and how does it relate to the “Water Tap” error?
A flow meter is a device that measures the amount of water entering the dishwasher. It sends signals to the control board. If the flow meter malfunctions, it can send incorrect signals, leading the dishwasher to believe it’s not receiving enough water and triggering the “Water Tap” error.
Can hard water cause the “Water Tap” error?
Yes, hard water can contribute to the “Water Tap” error. Mineral buildup from hard water can clog the water inlet valve, hose, and other components, restricting water flow. A water softener can mitigate this problem.
My dishwasher is new, and the “Water Tap” error is already appearing. What should I do?
If your dishwasher is brand new and displaying the “Water Tap” error, first ensure that the water supply valve is fully open. Then, check the inlet hose for kinks. If the problem persists, contact the retailer or Bosch directly for warranty service. It could be a manufacturing defect.
Is it possible to reset the “Water Tap” error on a Bosch dishwasher?
Sometimes, simply turning the dishwasher off and then back on can reset the error. If that doesn’t work, try disconnecting the power for a few minutes before reconnecting it.
Where can I find the water inlet valve filter in my Bosch dishwasher?
The water inlet valve filter is typically located at the point where the water inlet hose connects to the dishwasher. It’s usually a small screen or mesh filter inside the connector. You’ll need to disconnect the hose to access it. Refer to your dishwasher’s user manual for specific instructions.
