Understanding the Bosch Dishwasher Watertap Error: Causes and Solutions

When it comes to dishwashing, Bosch is a brand synonymous with quality and innovation. However, even the best appliances can encounter issues. One common problem Bosch dishwasher owners may face is the watertap error. This error can be frustrating, especially when you rely on your dishwasher for daily chores. In this blog post, we will explore what the Bosch dishwasher watertap error is, its causes, and how to resolve it effectively.

What is the Bosch Dishwasher Watertap Error?

The Bosch dishwasher watertap error, often indicated by error code E15 or similar, signals that the appliance is unable to fill with water. This error is a safety feature designed to prevent water damage to your home. When the dishwasher detects that it cannot fill with water, it stops the cycle and alerts you with the watertap error message.

Common Causes of the Watertap Error

Understanding the potential causes of the watertap error is essential for troubleshooting. Here are some common reasons why your Bosch dishwasher might display this error:

1. Water Supply Issues

The most straightforward cause of the Bosch dishwasher watertap error is a problem with the water supply. Ensure that the water supply valve is fully open and that there are no obstructions in the hose. If the water pressure is too low, the dishwasher may not fill adequately.

2. Kinked or Blocked Hose

A kinked or bent water supply hose can restrict water flow to your dishwasher, triggering the watertap error. Inspect the hose for any visible damage or bends, and ensure it is properly positioned without any blockages.

3. Clogged Water Inlet Filter

The water inlet filter is designed to prevent debris from entering the dishwasher. Over time, this filter can become clogged, leading to insufficient water flow. Regularly check and clean the filter to avoid this issue, which could be the cause of the Bosch dishwasher watertap error.

4. Faulty Water Inlet Valve

If the water inlet valve is malfunctioning, it may not open to allow water into the dishwasher. This can result in the watertap error. Testing and, if necessary, replacing the water inlet valve can resolve the issue.

5. Electronic Control Problems

Sometimes, the issue may not be mechanical but rather electronic. A malfunction in the control board can lead to incorrect signals being sent to the water inlet valve, causing the watertap error. If you suspect this is the case, consult a professional technician for further diagnosis.

Steps to Troubleshoot the Bosch Dishwasher Watertap Error

Now that we know the possible causes of the Bosch dishwasher watertap error, let’s look at how to troubleshoot and fix the issue:

Step 1: Check the Water Supply

Begin by ensuring that the water supply valve is turned on. If there are any issues with the water supply to your home, such as a shut-off due to maintenance or repairs, this could cause the watertap error. Open the valve completely and check if water flows freely.

Step 2: Inspect the Hose

Next, examine the water supply hose connected to the dishwasher. Make sure it is not kinked, bent, or obstructed. If you notice any damage, replacing the hose might be necessary. Additionally, ensure the hose is properly connected and tightened.

Step 3: Clean the Inlet Filter

Access the water inlet filter, which is typically located where the water supply hose connects to the dishwasher. Remove the filter and clean it thoroughly under running water to remove any debris or buildup. Reinstall the filter and check if the error persists.

Step 4: Test the Water Inlet Valve

If cleaning the inlet filter doesn’t resolve the issue, you may need to test the water inlet valve. Using a multimeter, check for continuity. If the valve is defective, it will need to be replaced. This is a more technical step, so if you’re unsure, it’s best to call a professional.

Step 5: Reset the Dishwasher

Sometimes, simply resetting the dishwasher can clear the watertap error. To do this, turn off the dishwasher, unplug it from the power source, and wait for about five minutes. Plug it back in and turn it on to see if the error persists.

Step 6: Call for Professional Help

If you’ve tried all of the above steps and the Bosch dishwasher watertap error still appears, it might be time to call a professional technician. They can perform a more in-depth diagnosis and repair any electrical issues or faulty components that may be causing the error.

Preventing the Bosch Dishwasher Watertap Error

While troubleshooting can help resolve the watertap error, prevention is always better than cure. Here are some tips to prevent encountering the Bosch dishwasher watertap error in the future:

Regular Maintenance

Regular maintenance is crucial for keeping your dishwasher running smoothly. Schedule periodic checks of the water supply hose, inlet filter, and valves to ensure everything is functioning correctly.

Monitor Water Supply

Keep an eye on the water pressure in your home. If you notice fluctuations or low pressure, it might be worth investigating further to prevent future issues.

Use Quality Water Supply Hoses
