Understanding the Bosch Dishwasher E15 Error Code
If your Bosch dishwasher is displaying the E15 error code, this usually indicates excess water has been detected in the machine. While this may sound worrying, don’t panic! There are some simple solutions you can try at home to resolve this issue to hopefully have your dishwasher back up and running in no time. The E15 error code signifies that too much water has been detected in the base of the dishwasher. The E15 error code is actually a protective measure—it indicates that Bosch’s anti-flood system has been activated. Bosch Official Support
The E15 error code on a Bosch dishwasher indicates a problem with the water intake or drainage process. This could be due to various factors, including: Clogged Water Inlet Valve, Faulty Water Inlet Valve, Low Water Pressure, Clogged Drain Hose, or Faulty Drain Pump. The dishwasher stops working when the E15 error appears because the anti-flooding feature prevents excess water from filling up your kitchen floor. It’s usually caused by a leak, perhaps in the sump basin, water tank, or hoses. Worst case, the leak might come from a broken fixture.
Common Causes of the E15 Error
- Using the wrong detergent—or too much of it: Households with soft water are especially prone to this. Using regular dish soap instead of dishwasher detergent, or just pouring in too much, can cause excessive suds. These suds can overflow and leak into the base, triggering the E15 code.
- Leaking hoses or seals: Wear and tear on internal hoses or door seals can cause drips or steady leaks that collect in the base tray.
- Clogged or damaged spray arms: When spray arms get clogged, cracked, or dislodged, water can shoot in the wrong direction—right into the seals or vents. That water can find its way into the base and set off the Bosch code E15.
- Dishwasher isn’t level: If your Bosch dishwasher isn’t installed on a level surface, water may pool in areas it shouldn’t. Uneven surfaces can lead to poor drainage and eventual leakage.
- Sump basin or pump issues: The sump basin collects water at the bottom of the dishwasher. If it’s cracked or the sump pump is malfunctioning, you might get water leaking underneath.
Step-by-Step Troubleshooting Guide
Step 1: Perform a Hard Reset
Sometimes, the E15 error can be caused by a glitch in the control board. Performing a hard reset may clear the error, which involves unplugging your dishwasher for five minutes and then powering it up again. If the error code persists, at least you’ll know that there’s almost certainly water in the base that needs removing.
Step 2: Tilt the Dishwasher
If you’re looking for a temporary fix to remove the water pooling in the bottom of your Bosch dishwasher, you can try tilting the appliance to help it to drain. Disconnect your Bosch dishwasher from its power source, either by unplugging or tripping the circuit breaker. Remove the lower front panel so you can see what’s happening. Gather towels to catch any spills. A shallow pan or dish is also a good idea—quite a lot of water may leak out when you’re trying this method. Carefully tilt the dishwasher backward at a 45-degree angle. Wait until the water has fully drained from the bottom of the machine. This should clear the error code.
Step 3: Clean the Filter
A severely clogged filter can cause water to pool in the bottom of your Bosch dishwasher, which can trigger the E15 error code. Locate the water filter (it’s on the bottom of your dishwasher). Twist the filter to dislodge it and then remove it. Use hot soapy water and a brush to give the filter a good clean. You can then dry it off and put it back into the dishwasher—making sure you put it back securely in the same position it previously was.
Step 4: Check the Drain Hose
A kinked or clogged drain hose can prevent proper water drainage, leading to water backing up into the base tray. Pull the dishwasher out from the wall to access the drain hose at the back. Check for any kinks, bends, or pinches in the drain hose. Ensure the drain hose is properly connected to both the dishwasher and the drain pipe/garbage disposal. iFixit Bosch Dishwasher Guide
Step 5: Inspect the Safety Switch
Remove the dishwasher door panel and kickplate. Locate the water safety switch behind a plastic cover, with a polystyrene disk under the switch. Carefully twist and pull on the safety switch to remove and take out the polystyrene disk. Thoroughly dry any residual water in the area. Place the disk and the switch back into position, ensuring they are secured correctly. Replace the door panel and kickplate. Restore power to the dishwasher and turn the water back on. Then run a test cycle to make sure the error doesn’t come back.
Frequently Asked Questions (FAQs)
Q: Can I fix the E15 error myself?

Q: How do I prevent the E15 error from recurring?
A: Regular maintenance is key. Clean the filter monthly, use the recommended amount of high-efficiency detergent, ensure the dishwasher is level, and check hoses and seals for wear. Running a cleaning cycle with a dishwasher cleaner every few months also helps.
Q: Is it safe to run my dishwasher with an E15 error?
A: No, you should not run the dishwasher until the error is resolved. The E15 code indicates a potential leak, which could cause water damage to your kitchen or harm the appliance.
