This guide dives into the most common Bosch dishwasher error codes, what they actually mean, and—perhaps most importantly—how you can try to fix them yourself before calling in the pros.
Why Bosch Dishwashers Display Error Codes
Modern Bosch dishwashers are packed with sensors and smart diagnostics designed to keep things running smoothly. When something goes off track, the appliance alerts you with a specific code—usually a combination of numbers and/or letters—on the display. These codes point to the underlying issue, from water supply hiccups to heating glitches.
Common Bosch Dishwasher Error Codes
Let’s break down the error codes you’re most likely to encounter.
E01 / E02: Heating Issues
- What it means: The dishwasher’s heating element isn’t working as it should.
- What to check: Sometimes, the issue is as simple as a tripped breaker or a loose wire. In other cases, the heating element or control board might need replacement.
E09: Faulty Heating Element
- What it means: The water isn’t heating up because the heating element has failed.
- How to fix: If you’re handy, you might check for continuity in the element using a multimeter. Otherwise, this is often a job for a technician.
E15: Water Leak Detected
- What it means: There’s water collecting in the base of the dishwasher, likely due to a leak.
- Quick fix: Unplug the appliance and tilt it slightly to drain out the water. Inspect the hoses and seals for visible leaks. If you’re still seeing the code, further inspection is needed.
E24: Drainage Problems
- What it means: The dishwasher isn’t draining properly, which might mean a clogged filter or hose.
- Steps to try: Clean the filter, check the drain hose for kinks or blockages, and ensure the garbage disposal (if connected) isn’t clogged.
E25: Pump Problems
- What it means: Similar to E24, but points more directly to an issue with the drain pump itself.
- Solution: Sometimes, cleaning the pump area fixes it. If not, the pump might need replacement.
Less Common Codes and What They Indicate
E04: Water Flow Meter Error
- This code means the flow meter isn’t detecting water properly. The root cause could be a faulty sensor or simply a kinked hose.
E22: Filter Blockage
- A simple one—clean the dishwasher’s filter and run a test cycle.
E27: Voltage Too Low
- This error pops up if the power supply dips below safe levels. Check your home’s voltage or try plugging into another outlet.
Troubleshooting Tips Before You Call for Help
Before you assume the worst, a few quick steps can sometimes resolve even stubborn Bosch dishwasher error codes:
- Restart the dishwasher: Sometimes, unplugging the appliance for five minutes can reset the control board.
- Double-check the door: If the door isn’t fully closed, the dishwasher might throw an error.
- Inspect hoses and filters: Many codes relate to simple blockages or loose connections.
When to Call a Professional
If you’ve tried the basics and the error code keeps returning, don’t let frustration get the better of you. Some repairs, especially those involving internal sensors or electrical components, are best left to certified professionals. Attempting complex repairs without proper experience can end up costing more in the long run.
