What Does E15 Mean On A Bosch Dishwasher?

Facing an E15 error on your Bosch dishwasher indicates a potential leak. Here’s what you need to know:

  1. Meaning: This code signifies a detected leak beyond the intended water path, triggered by the dishwasher’s internal leak sensor.
  2.  Safety Feature: The E15 code is a safety measure. It halts the operation and shuts off the water supply. This way, the appliance prevents further water accumulation and potential flooding.
  3.  Impact on Use: The dishwasher will not operate until the leak is fixed. This may force you to do the dishes manually
  4. Warning Signs: Besides the E15 code, the bosch dishwasher displays a flashing tap symbol or might beep continuously
  5.  Importance of Addressing the Issue: Ignoring the E15 code can lead to water damaging flooring and cabinets and posing potential slip or electrical shock risks.

Remember, the E15 code is a warning, not a cause for panic. Promptly addressing the leak can prevent further damage and ensure your dishwasher’s smooth operation.

Why Is My Dishwasher Stuck On E15?

At first glance, the E15 error code may seem like a cryptic message. The many culprits behind this issue can confuse you. But, don’t surrender to your confusion, and let’s break down the common causes behind your Bosch dishwasher e15 code.

1- Excess Detergent

If you overuse the dishwasher soap or accidentally use the wrong detergent, you will find excess suds overflowing from the dishwasher and leaking into the base.

2- Clogged Components

Food debris, suds, and other stuck particles can accumulate in the drain filter or hose. This buildup hinders proper drainage and causes water to back up and reach the leak sensor.

3- Sump Basin Leak

Though some water remains in the sump basin after washing, a cracked basin or faulty seal can leak, triggering the E15 error and safety leakage protection system to prevent water damage.

4- Faulty Inlet Hose

The inlet hose acts as a lifeline by delivering clean water from the main supply to the appliance for effective dish cleaning.

When torn or damaged, this hose can be a possible cause of water leakage.

5- Problematic Water Tank

The dishwasher tank, responsible for storing clean dishwashing water, can leak if damaged, cracked, or poorly attached. In this case, Water leaks from a faulty tank to the base.

How To Fix Bosch Dishwasher E15 Code

Now that we’ve covered the possible causes for a Bosch Dishwasher E15 problem, it’s time to find proper fixes. Let’s troubleshoot each culprit:

1- How To Fix Excess Detergent

This is an easy fix that doesn’t require much DIY expertise. You can bring a dry clean cloth or a sponge along and follow these steps:

  1. Open the dishwasher door and remove the lower rack.
  2. Use your sponge to wipe away any excess suds from the base.
  3. Run a rinse cycle to ensure all the suds are gone. Don’t load any dishes.

2- How To Fix Clogged Components

When it comes to clogged components, you should start by checking the drain filter before the hose. To troubleshoot a blocked filter, you may need a screwdriver and a cleaning brush.

  1. Locate the drain filter: Look for it at the bottom center of the dishwasher tub. Remove the lower rack and the securing screws of the panel.
  2. Clean the filter. Brush off debris and obstruction, detach it with a screwdriver, and rinse under running water. Reinstall securely.
  3. Inspect the drain hose. This connects the filter to the drainpipe at the back.
  4. Loosen the clamps. Use a screwdriver to loosen the clamps holding the hose to the filter and drainpipe.
  5. Clear blockages: Insert a wire coat hanger to push out any clogs in the hose.
  6. Replace the hose: If kinked or damaged, replace it with a new one.

3- How To Fix Sump Basin Leaks

If you suspect a leaky sump basin to be the root cause behind your Bosch dishwasher e15 problem, you should seek professional help. This is a complex component for DIY newbies. But if you are certain about your skills, follow these steps:

  1. Access the sump basin. Remove the lower rack, spray arm, and bottom panel. Locate the basin (large, round, or rectangular) at the bottom center. Remove the drain pump and basket for better access.
  2. Clean and perform a thorough inspection. Use a dry cloth to remove water. Look for cracks in the basin.
  3. Prepare and apply epoxy. Sand the area for adhesion. Follow water-resistant epoxy instructions for mixing and application. Smooth it out and let it dry completely (around 48 hours) before using the dishwasher.

4- How To Fix Faulty Inlet Hose

In most cases, replacing the faulty inlet hose is the only fix to restore its functionality. You can easily do this by doing the following:

  1. Locate the hose. Most Bosch dishwasher models offer easy access to the water inlet hose at the back. But some other models might require reaching it from the bottom, potentially behind a removable toe kick (bottom) panel. So, refer to the manual to determine the specific location.
  2. Use a wrench to disconnect the hose from the water valve. There is a securing nut to remove.
  3. If it appears damaged or kinked, install the new hose.

5- How To Fix Problematic Water Tank

As with most components of your Bosch dishwasher, you can find this tank at the base of your appliance. So, you can find it after removing the bottom panel.

  1. Look for a cylindrical container that appears like a reservoir. This is your tank.
  2. Detach it from the dishwasher by disconnecting the hoses and wires.
  3. Clean the water tank with a soft brush and warm water, or replace it if it is cracked or broken.
  4. Reattach the water tank to the dishwasher and reconnect the hoses and wires.

How To Reset Bosch Dishwasher E15?

Sometimes, the E15 error code is just a temporary glitch that you can fix by resetting your Bosch dishwasher. Turn off the power button or unplug your dishwasher for 15 minutes, then restart it. If the error persists, further troubleshooting might be needed.
