What Does Bosch Water Tap Error Mean And How To Fix it?

Bosch dishwashers are known for their sleek designs, unique features, and high-end performance. They started using a self-diagnosis system in their dishwashers to help save time and energy. 

These diagnosis systems can report the problem with the dishwasher’s fault code and will even help suggest how to fix it. This is great for anyone who is constantly looking for ways to improve their experience with their appliances.

When your dishwasher’s display shows a water tap error, it usually means that some appliance parts are broken or not working properly. To fix this issue, you should make sure that these parts are replaced or repaired.

If your dishwasher shows a water tap error on display, then there are several things that you can do to resolve it. For example, you may need to check if there is a clogged-up filter or not, or you may need to replace a faulty part. 

If the dishwasher displays a water tap error, there are a few things you can try to do to fix the problem. You must be able to properly diagnose the issue and figure out what is causing it. 

Problem No. 1: Filter Blockage

Too much sediment can clog the filter and cause it to stop working. If water can’t flow through the connection, you’ll need to remove the inlet hose and clean it out. In case of blocked filters on the supply hose or hose, make sure that the inlet hose filter is cleaned first.

How To Clean The Inlet Filter?

The inlet filter is an important part of the air conditioning system and needs to be cleaned regularly. Without regular maintenance, the filter may not be able to remove dirt and particles from the incoming air, leading to a polluted and unhealthy environment.

• You need to turn off the water.
• Connect the hose to the water tap and remove it.
• Run water through the filter to clean it.
• Cleaning should be done with a small brush.
• Check for leaks by connecting the hose.
• There may be a kink in the supply hose.
• Untwist any visible kinks on the appliance by pulling out slightly.
• Pull the appliance out slightly and untwist any visible kinks or bends in the cold-water fill and wastewater hose.

Problem No. 2: Low Water Pressure

The water pressure is the force exerted by liquid moving through a pipe per unit area. It can be measured in pounds per square inch or kilograms per square centimeter. 

How To Check The Water Pressure?

The pressure regulator helps to maintain the water pressure at an optimum level. A bucket can be used to measure the water pressure at the tap. The tap should be able to flow approximately 10 liters of water per minute when fully opened. Check with your plumber if it is not flowing well.

• Ensure that the tap has enough water pressure. You can check it using a pressure regulator. 
• Remove the hose and close the water tap.
• Turn off the water tap and place a bucket below the faucet.
• Water should come out at a rate of approximately ten liters per minute.
• If you are experiencing low water pressure, you should contact your plumber.

Problem No. 3: Kinked Or Blocked Hose

Is your dishwasher supplying clean water? If it has a kink or bend in it, there could be an issue with your supply hose, leading to water supply issues. 

If a dishwasher is not draining correctly, it is important to inspect the supply hose and untwist any visible kinks or bends. If there are kinks or bends, the dishwasher would be unable to wash the dishes effectively.

The dishwasher supply hose is a plastic tube that connects to the water source and your dishwasher drain. Unfortunately, this hose often gets twisted or kinked as it moves from the appliance to the sink, leading to clogging in the hose and dishwasher. 

The solution is simple: untwist any visible kink or bend in the dishwasher’s supply hose before it reaches your sink.

How To Check That There Are No Kinks In The Supply Hose?

• If any kinks or bends are visible in the cold-water fill hose or the wastewater hose, pull the appliance slightly out and remove them. 
• The appliance should be lifted out slightly, and any visible kinks should be undone.

Understanding E22 Error Code

You have a blocked dishwasher filter if you receive an error code E22. Filters should be cleaned regularly to prevent food from clogging them. The filter is located under the wire rack at the bottom of the dishwasher.

It can be cleaned with warm, soapy water once the filter is removed. If you want to make sure you get everything out of the mesh, you can use a soft bristle brush.

When you load your dishwasher, the condition of the dishes will determine how often you need to clean the filter. Cleaning your filter every two to four months is a good idea if you rinse your dishes before loading.

Understand E24 Error Code

A dishwasher E24 error means that the drain is not working properly and makes noise. This error can be fixed in three ways. The first step is to ensure that the filter isn’t clogged. If that is not the problem, you will need to check the pumps and hoses.

The drain pump cover can come loose, preventing it from pumping water out. You can find the pump under the filter; make sure it is securely fastened once you find it.

Last but not least, check the inlet and drain hoses in the back of the machine if the pump’s lid is closed. In drain hoses, food can clog them and prevent them from draining.

Final Words

When a Bosch dishwasher displays the watertap error, it indicates a problem with the water supply, often related to the Aquastop hose, waste water hose, or a blockage in the system. To diagnose and rectify this issue, start by inspecting the supply or Aquastop hose for kinks or obstructions that might impede water flow. Similarly, a blocked hose can prevent water from entering or leaving the dishwasher as intended. Conduct a thorough inspection of these hoses, ensuring they are not twisted, crushed, or blocked. If any blockages are found, carefully remove them to restore proper water flow.

Furthermore, the inlet filter and drain hose should not be overlooked. A clogged inlet filter can restrict water from entering the dishwasher, leading to the watertap error. To address this, turn off the water connection and gently clean the inlet filter of any debris or buildup. Similarly, check the drain hose for any obstructions that might prevent waste water from exiting the dishwasher efficiently. Regular maintenance, including checking these components and ensuring the use of proper rinse aid, can significantly reduce the likelihood of facing such errors. If the problem persists, contacting a Bosch service expert is recommended to ensure a professional and accurate water installation check, guaranteeing your dishwasher returns to optimal performance.
