Understanding the E15 Error Code

The E15 error code on a Bosch dishwasher is one of the most common and frustrating problems faced by many homeowners. This error code indicates that there is a leak in the dishwasher, which has triggered the flood protection system to activate and shut off the appliance.

Understanding this error code is crucial for troubleshooting and fixing the issue, so let’s dive into what it means and how to deal with it.

Common Causes of the E15 Error Code

The E15 error code on a Bosch dishwasher can be frustrating and inconvenient, leaving you with dirty dishes and a malfunctioning appliance. This error code is an indication that there is an issue with the water supply to your dishwasher. Several common causes of the E15 error code can help you identify and troubleshoot the problem.

  1. Clogged or Kinked Water Supply Hose: One of the most common causes of the E15 error code is a plugged or kinked water supply hose. Over time, debris and mineral deposits can build up in the hose, causing it to become blocked. Additionally, if the hose becomes kinked or bent during installation or use, it can restrict water flow to the dishwasher.

Solution: Inspect the water supply hose for any visible blockages or kinks. If found, carefully remove them using pliers or a pipe cleaner. You may also need to replace the hose if it appears damaged.

  1. Faulty Water Inlet Valve: The water inlet valve controls how much water enters your dishwasher during each cycle. When this valve malfunctions, it can either allow too much or too little water into your dishwasher, triggering an E15 error code.

Solution: Test the water inlet valve by performing a continuity test with a multimeter. If there is no continuity, then you will need to replace the valve.

Water Supply Issues

Water supply is an essential component in the functioning of a dishwasher. Without a proper water supply, the dishwasher will not be able to clean dishes effectively and efficiently.

The water in the dishwasher acts as a medium to dissolve detergent and carry it to the words, removing any food particles or stains. It also helps in rinsing off the detergent residue from the dishes after they have been cleaned.

In addition, an adequate water supply ensures that all parts of the dishwasher are adequately lubricated and prevents any damage caused by friction between moving parts. Insufficient or poor-quality water can lead to mineral buildup and clogging of filters, which can affect the performance of your dishwasher.

Common Water Supply Issues Leading to E Error Code

There are several reasons why your Bosch dishwasher may display an E error code due to water supply issues. Some of these common issues include:

  • Low Water Pressure: If your home has low water pressure, it may result in inadequate water flow into your dishwasher. This can cause problems with cleaning efficiency and lead to an E error code being displayed on your machine.
  • Clogged Filters: Over time, debris such as food particles, grease, or hard minerals can accumulate in the filters of your dishwasher’s inlet valve or spray arms. These clogs restrict water flow into the machine, resulting in an E error code.
  • Faulty Inlet Valve: The inlet valve controls how much water enters your dishwasher during a cycle.

Blocked Filters

One of the most common causes for a Bosch dishwasher to display an E error code is blocked filters. Dishwashers have various filters that are designed to trap food particles and debris, preventing them from clogging up the drain or damaging the dishwasher’s components. Over time, these filters can become clogged with buildup and need to be cleaned or replaced.

There are typically three types of filters in a Bosch dishwasher: the primary filter, the fine filter, and the microfilter. The primary filter is located at the bottom of the dishwasher and catches larger food particles such as bones or seeds. The fine filter is situated above the primary filter and captures smaller particles like grains of rice or coffee grounds. The microfilter is located at the back wall of the dishwasher and catches any remaining debris before it reaches the drain pump.

When these filters become blocked, it can disrupt the flow of water within your dishwasher, causing it to display an E error code. This blockage can also lead to poor cleaning performance or even cause damage to other parts of your appliance.

So, what causes these filters to become blocked? Here are some common reasons:

  1. Food Debris: The primary reason for blocked filters is food debris that accumulates over time during dishwashing cycles. These small pieces of food can easily get trapped in any one of your dishwasher’s filters.
  2. Hard Water Buildup: If you live in an area with hard water, mineral deposits can build up on your dishwasher’s internal.

Faulty Sensors

The E error code on a Bosch dishwasher indicates that there is a problem with one of the dishwasher’s sensors. Sensors are an essential component of any modern dishwasher, as they help to monitor and regulate various functions such as water temperature, detergent levels, and cycle duration. When one or more sensors fail or become faulty, it can result in the E error code being displayed on the control panel.

There are several possible causes for faulty sensors in a Bosch dishwasher. One common cause is wear and tear over time, as dishwashers are used frequently and exposed to high temperatures and harsh detergents. This can cause the sensors to malfunction or become inaccurate. Another possible cause is water damage from leaks or spills within the dishwasher itself, which can corrode the sensor components and lead to malfunctions.

In addition to general wear and tear and water damage, another common culprit for faulty sensors is debris buildup. Over time, food particles, grease, and other debris can accumulate in the dishwasher’s interior parts, including the sensors. This buildup can block or interfere with sensor readings and cause them to malfunction.

Fortunately, there are some steps you can take to fix faulty sensors and resolve the E error code on your Bosch dishwasher. The first step is to check all visible areas of your dishwasher for any signs of debris buildup or corrosion. If you notice any issues, carefully clean these areas with a damp cloth or sponge.

  • Step 1: Turn off the Power

Before attempting any repairs, always make sure to turn off the power to your dishwasher. This will prevent any potential electrical hazards and also stop water from being pumped out if the machine is currently in use.

  • Step 2: Check for Visible Leaks

The first thing you should do when dealing with an E15 error code is to check for any visible leaks. Carefully inspect the bottom of your dishwasher and look for signs of water pooling or dripping. If you find any leaks, try to determine where they are coming from so you can address them adequately.

  • Step 3: Empty the Base Pan

If there are no visible leaks, then it’s likely that water has accumulated in the base pan of your dishwasher. To fix this, you will need to remove all dishes from inside and carefully tilt the machine forward until excess water drains out of the base pan.

  • Step 4: Clean and Dry the Base Pan

Once all visible water has been removed, use a towel or sponge to thoroughly clean and dry out the base pan. Any remaining moisture could cause further issues down the line.
