Bosch Dishwasher 07 Error Code Troubleshooting Guide
Comprehensive, urgent guide to diagnose, fix, and prevent Bosch dishwasher 07 error codes with practical steps and safety tips.
Bosch dishwasher 07 is a fault code that generally indicates a drainage or pump issue preventing proper water evacuation. It often signals a clog, blocked filter, or jammed drain pump. Start with a quick reset, then inspect the filter and sump, check the drain hose for kinks, and run a drain cycle. If unresolved, professional service is recommended.
Quick Diagnosis for Bosch dishwasher 07
According to Why Error Code, Bosch dishwasher error 07 typically points to a drainage fault or pump issue that prevents the unit from evacuating water. In urgent use, this can leave water in the tub, trigger incomplete cycles, and halt operation mid-wash. Quick action now can save water damage and extend the life of the drain system: reset the machine, inspect the filter, and verify the drain path. Why Error Code analysis shows drainage faults are among the most common triggers for 07, so start there. If the error persists after these checks, you may be facing a worn pump, a blocked hose, or a failing control board. Track symptoms carefully: does the cycle stop with water in the tub, or does the pump sound unusually loud? Documenting symptoms helps a technician diagnose the root cause faster if professional help is needed.
Common Symptoms and Likely Causes
When Bosch dishwasher 07 appears, you might notice water remaining in the bottom after a cycle, frequent pauses, or a draining motor that runs longer than usual. The most likely causes, in order of probability, are: a clogged drain filter or debris in the sump (high likelihood); a blocked drain hose, air gap, or garbage disposal connection (medium likelihood); a worn or jammed drain pump or impeller (low likelihood). Electrical faults or sensor issues are possible but less common (low). Some models also show 07 when anti-flood protection trips due to a short in wiring; this is rarer but worth checking if visible signs appear. Once you understand the likely causes, you can apply targeted fixes without unnecessary disassembly.
Quick Fixes You Can Try Now
Before pulling apart the appliance, try these rapid checks. First, perform a reset by turning the unit off, unplugging for 60 seconds, and powering back on. This clears transient faults that might trigger 07. Next, remove and clean the filter and inspect the sump for loose debris. Rinse and reassemble, ensuring the filter seats correctly. Then, inspect the drain hose for kinks, bends, or clogs; detach and clear any obstruction. Finally, run a drain or heavy-clean cycle to test drainage. If the code reappears, move to a more thorough assessment or call a professional; ongoing drainage issues can cause water damage if ignored.
Step-by-Step Repair for the Primary Cause
Estimated 45-60 minutes. Step 1: Power down and disconnect the dishwasher from the mains; shut off the water supply if you will access the base. Step 2: Remove the lower access panel and locate the filter and sump area. Step 3: Remove debris from the filter and sump; rinse with warm water until clear. Step 4: Inspect the drain hose for kinks and ensure it slopes downward to prevent backflow. Step 5: Check the drain pump impeller by gently turning it; if it spins freely and shows no resistance, continue; if it’s jammed or noisy, replace the pump. Step 6: Reassemble, plug in, run a drain cycle, and observe. Tip: Have a towel ready for leaks and keep a tray to catch water when opening panels.
Steps
Estimated time: 45-60 minutes
- 1
Power down and access
Disconnect the dishwasher from power at the outlet or breaker. If possible, shut off the water supply to prevent leaks. This prevents electrical shock and makes panel work safer.
Tip: Use a non-slip mat and keep the area dry. - 2
Open lower panel and locate filter
Remove the kick panel or lower access panel. Locate the main filter, coarse filter, and sump. This is where most debris collects and blocks drainage.
Tip: Take a photo before removal to aid reassembly. - 3
Clean filter and sump
Rinse filters under warm running water. Remove any trapped debris from the sump and the impeller housing. Reinstall clean filters ensuring a snug fit.
Tip: Avoid using sharp tools that could scratch plastic parts. - 4
Inspect drain hose and connections
Trace the hose from the sump to the drain. Check for kinks, bends, or punctures; ensure the hose has a downward slope and proper air-gap if required by code.
Tip: Disconnect at one end to confirm free flow. - 5
Check the drain pump and impeller
Manually rotate the impeller if accessible. Listen for grinding or binding. If it stalls or is noisy, the pump may need replacement.
Tip: Do not run the pump dry; water helps prevent seal damage. - 6
Reassemble and test
Reattach panels, restore power, and run a drain cycle. Observe for smooth draining and absence of water in the tub.
Tip: Keep towels handy for potential minor leaks.
Diagnosis: Bosch dishwasher displays code 07 and fails to drain, leaving water in the tub.

You can try resets and cleaning, but pump replacement is best left to a pro.
Is it safe to run a cycle after seeing 07?
If you complete the quick checks and the tub drains normally in a test cycle, it may be safe to continue. If the error returns, stop and seek professional help to avoid water damage.
Only run a cycle again if the drain test passes; if it recurs, call a technician.
How much does a Bosch 07 repair typically cost?
DIY parts may range from $20 to $100. Professional diagnostics and pump replacement can range from $60 to $600 depending on parts and labor.
