What Does the Flashing Tap Symbol on your Neff Dishwasher mean?
If you have been getting some sort of mysterious flashing tap symbol on your Neff dishwasher, then you are not alone. To many, this is a sort of warning light that’s always unnerving if you do not know what it means or how to resolve it. Well, do not worry; this is relatively common and the solutions are pretty straightforward. This blog will walk you through what the flashing tap symbol means, why it may be occurring, and how to fix it in steps.
What does the flashing tap symbol mean?
The blinking tap icon signals a warning by your dishwasher and means there is an issue in the water supply. In other words, your appliance is trying to tell you that it is either not getting enough water for its operation or it cannot drain the water it has already used. This could be because of several reasons, which include blockages and interruptions to the water supply.

Causes of the Blinking Tap Icon
The blinking faucet icon does not always indicate a problem that you cannot fix yourself at home. Most of the time, it will be because of something easily solvable by you. Below are some of the most common causes of this problem:
Blockages in Filter or Drain Hose
A blocked filter or drain hose can be the cause of improper water inflow or outflow into or from the dishwasher.
Kinked or Damaged Water Supply Hose
If the supply hose that connects your dishwasher to the water source is kinked, bent, or damaged, it can restrict water flow.
Water Supply Issue
The problem might not be with your dishwasher at all. For instance, if your home’s water supply pressure is low or cut off, the dishwasher will display the alert.
Faulty Aquastop System
Aquastop is a protection device that many Neff dishwashers are equipped with. It serves to automatically cut off the water intake in case of a leakage. The failure of such a device can be one good reason for the tap symbol to appear.
Dirt or Faulty Water Intake Valve
With time, the element controlling the entry of water into your dishwasher may block due to junk that enters the valve or may have simple wear and tear.
Miscommunication Between Dishwasher Components
Sometimes, an internal error or a sensor malfunction can cause the tap symbol to flash even though the water supply is fine.
How to Fix the Flashing Tap Symbol
Now that you have an idea of what might be causing this issue, here are some actionable steps to troubleshoot and resolve it:
1. Check the Filter and Drain Hose
Turn the dishwasher off and unplug it for safety. Remove the filter, generally located at the bottom of the dishwasher. Clean out the food particles, grease, or debris. Check if there is blockage or bends in the drain hose. If so, remove the blockage with the help of a flexible cleaning brush.
2. Check the Water Supply Hose
Ensure that the hose is not kinked or twisted. Straighten it if necessary. Check it for wear and damage. If you find any cracks or leaks, replace the hose.
3. Check Your Home Water Supply
Run a faucet in your home to confirm the water pressure is on. If there is no water or low water pressure, call your water supplier to get the issue resolved. Check the water valve that supplies water to the dishwasher’s supply hose to make sure it is fully opened.
4. Check the Aquastop System
Check for any leaks underneath and around the dishwasher. If you notice some water, it may indicate that the Aquastop has engaged because of a leak somewhere. If you suspect that the Aquastop is faulty, you may need to contact Neff customer service or an appliance technician for assistance.
5. Clean the Water Intake Valve
Turn off the water supply and disconnect the intake hose from the dishwasher. Clean the screen from any junk off the valve. Replace the hose in its original position and ensure it’s tightly connected.
6. Reset the Dishwasher
At times, your dishwasher just needs a little reset to jog some minor faults back into place. Just switch it off, pull it from the power, leave it for about 10 minutes, plug it on, and restart.
7. Call for Professional Help
If all else fails, this may be a good time to call in a professional. Reach out to Neff’s customer service for help or contact a qualified appliance technician to further diagnose and repair the problem.

How to Prevent This in the Future- Running Your Dishwasher
So, to avoid other instances of a flashing tap symbol and to maintain your dishwasher: clean the filters more regularly and avoid blockage. Periodically check hoses for wear, tear, or blockages. Don’t overload the dishwasher, as this can affect drainage and water flow. Use cleaning products in the dishwasher designed for dishwashers to reduce the amount of residue left behind. Schedule annual maintenance checks, especially if your dishwasher is an older model.
Conclusion
The flashing tap symbol might feel daunting at first, but in most cases, it points to an issue that can be resolved quickly with a little troubleshooting. Remember to stay patient and methodical in your approach. By following the steps outlined above, you’re well on your way to restoring your Neff dishwasher back to normal operation.
If none of the above steps work, do not be afraid to call a professional. It’s worth the effort to have a fully functioning dishwasher that saves you time, energy, and the aggravation of washing dishes by hand.
