Bosch dishwashers have a self-diagnosis built-in that enables them to identify a fault and present an error code. One error code that may pop up is the e15 error code, and today, I’ll share a quick guide to Bosch dishwasher troubleshooting e15.
A Bosch dishwasher typically displays the e15 error code when it detects a leakage around its base. In most cases, the cause is a leaky hose, sump basin, or water tank.
If that’s not it, it could be a glitch, excess suds, broken fixture, obstructed drainage system, or faulty sprinkler, pressure switch, or flow meter.
So, to troubleshoot the error code, you have to consider the eight issues, which I’ll take you through, and fix them. But as you’ll realize, the fixes are straightforward, making the troubleshooting DIY.
Let’s jump in!
In a rush? See below a quick Bosch dishwasher e15 error code troubleshooting guide:

What Does E15 Mean On a Bosch Dishwasher?
The code E15 appears on a Bosch dishwasher when the dishwasher senses a leakage. These dishwashers usually have a leakage protection system that senses water around the base and triggers the error code.
What Causes E15 Error On Bosch Dishwasher?
Generally, the e15 error code appears due to any of these eight issues:
1. Water Leakage
Since the anti-flood or leak detection feature triggers the e15 error code when it detects a leakage, as I mentioned, it makes sense to check for any water leakage. In that case, inspect the following for potential leakage:
- Hoses – Inspect the water supply and drain hose for leakage. It could be that the hoses are kinked, poorly installed, or damaged and, as a result, causing water leakage.
- Water tank – The tank could also leak due to wrong installation or damage, so you should inspect it for the two issues.
- Sump basin – The sump could also trigger the error code e15 if it’s leaky and could be due to a loose or worn-out sump seal or the basin itself being damaged.
2. Electronic Glitch
Sometimes a Bosch dishwasher displays error codes due to an electronic glitch, which could be any code. So, you can’t rule out this reason regarding the e15 error code.
Generally, electric appliances like dishwashers suffer a glitch at some point; all it takes is resetting the appliance. So, consider a Bosch dishwasher e15 reset here, and I’ll share the quick process in a few.
3. Excess Suds
If there are many suds, the error code e15 may pop up. In such a case, the excess suds lead to the extra water flow to the dishwasher’s base; when the anti-flood sensor notices that, it sends the e15 warning code.
Overall, suds may form in excess due to either using the wrong detergent or applying too much of the correct detergent.
4. Broken Fixture
Sometimes the e15 error code pops up when the dishwasher sensors sense a broken fixture, such as the drain pump, drain valve, fill valve, or heating element. So check all these fixtures for breakage and replace what’s faulty.
5. Obstructed Drainage System
A significant obstruction in the dishwasher’s drain system could lead to an overflow, and the water could flood the dishwasher’s base. The anti-flood feature may activate once that’s the case, resulting in the e15 error code.
6. Faulty Sprinkler
Sometimes the Bosch dishwasher displays the error code e15 due to a faulty sprinkler. The sprinkler often fails due to a worn-out motor, blocked filter, or defective pump.
7. Faulty Water-Level Pressure Switch
If the water-level safety switch fails, you can expect your Bosch dishwasher to display the e15 error code. In such a case, the safety switch won’t regulate the amount of water entering the dishwasher, which is its job.
8. Defective Flow Meter
Lastly, consider that the flow meter could be defective; if so, it’s unable to measure the amount of water flowing into the dishwasher, which may lead to excess water flow, which could flood the base.
How Do I Fix Error Code E15 On Bosch Dishwasher?
Now that you know what to check when your Bosch dishwasher displays the error code, it should be easy to fix. Generally, here’s how to fix error e15 on Bosch dishwasher:
Step 1 – Check for water leakage
It’s essential first to check if there’s any leakage, and the parts to inspect are the hoses (supply and drain hoses), water tank, and sump basin.
But first, you may try a 45-degree tilt to drain the accumulated water. In that case, disconnect and push the dishwasher off the wall, tilt it to a 45-degrees, and drain the water. While at it, wipe dry the base of the dishwasher to ensure there’s no water.
Note, however, that while this may stop the error code, it doesn’t fix the underlying issue. You need to address that too.
In the case of a leaky drain hose, unkink it if the cause is kinking, re-install it if it’s poorly installed, and replace it if it’s damaged. Consider replacing the water tank, too, if it’s damaged.
However, in the case of a leaky sump basin, first, try to tighten any loose connection. But if that doesn’t work or the sump basin is damaged, replace it.
Step 2 – Reset the dishwasher
Just in case the issue is a glitch, a reset may help. Here’s how to reset e15 error on Bosch dishwasher:
- Disconnect the dishwasher from the power – probably by unplugging it
- Wait for 5-15 minutes to reconnect it
- Start the washer to see if the e15 error code is there
- If it is, check out the remaining steps
Step 3 – Check for excess suds
Is your dishwasher foaming too much? If yes, there is a chance you are using the wrong detergent. So, check if you are using what the manufacturer recommends.
If you use the correct detergent, but the suds are still forming in excess, you are likely putting too much of it. Hence, you need to reduce the amount.
Step 4 – Reset the water-level safety switch
Consider resetting the water-level safety switch, as it’s likely to trip when the dishwasher detects a leakage. Here’s how to do it:
- Disconnect the dishwasher and turn off its water supply
- Remove the door panel, bottom panel, and toe kick plate to access the safety switch
- Pull out the water-level safety switch
- Wipe out any water at the bottom of the dishwasher
- Reassemble everything
Step 5 – Check for a broken fixture
Sometimes the cause of the leakage could be a damaged fixture, and the ones to check include the drain pump, drain valve, fill valve, and heating element.
Thus, inspect all these components keenly and replace the one that shows signs of fault.
Step 6 – Inspect the drainage system for blockage
Another reason the Bosch dishwasher may detect leakage is if it won’t drain properly, possibly because of a blocked drain system. In that case, examine its drainage system for clogging and clean the affected part.
Step 7 – Examine the sprinkler, pressure switch, and flow meter for fault
The last step is to inspect the sprinkler, pressure switch, and flow meter for signs of wear or damage. And if so, replace the culprit. If you can’t do it, call a dishwasher expert.
Bosch Dishwasher Silence Plus 44 DBA Troubleshooting E15
To troubleshoot a Bosch Silence Plus 44 DBA dishwasher displaying the e15 error code, first determine a potential leakage source. In that case, inspect the hoses, water tank, and sump basin for leakages and possibly replace the leaky part.
After that, consider hard-resetting the dishwasher if the error code won’t go to fix a possible electronic glitch. And if the hard reset doesn’t work, tilt the dishwasher to about 45 degrees to drain the accumulated water and then reset the water-level safety switch.
