Bosch Error Code F24
Drain error (Alternative display code for E24).
Safe DIY repairWhat the Bosch F24 code means
The F24 error code on a Bosch dishwasher is a diagnostic fault reported by the appliance's main control board. In plain terms, it signals drain error (Alternative display code for E24). When this code appears, the dishwasher pauses its current cycle as a safety measure to prevent water damage, electrical strain, or mechanical wear, and waits for the homeowner or a technician to inspect the underlying cause. Understanding exactly what the Bosch F24 code points to — and the most common parts and behaviors that trigger it — lets you decide whether this is a quick five-minute fix you can perform yourself, or a job that warrants a professional service call.
Tools and supplies you'll need
No specialty tools are required for this repair. You should still keep a small towel and a flashlight handy in case you need to mop up residual water or peer into a tight cavity.
Comprehensive step-by-step troubleshooting & fixes
Follow each step in order. Before you begin, unplug the appliance from the wall outlet or flip the dedicated breaker so the unit is fully de-energized. Keep a towel and a shallow pan within reach in case any residual water escapes during the repair.

Even though this is a beginner-friendly repair, always unplug the dishwasher from the wall outlet and shut off the water supply valves behind it before opening any access panel or disconnecting a hose. Keep a towel and shallow pan within reach to catch residual water, and never bypass the door lock, lid switch, or any safety interlock to force a cycle to continue while the fault code is active.
Always disconnect power before servicing any appliance.
After the repair: how to verify the F24 code is gone
Once you've completed the repair, restore power to the Bosch dishwasher and run a short test cycle — a quick rinse, drain, or self-diagnostic mode, depending on your model — to confirm the F24 fault has cleared. Watch the display for the first two to three minutes: if the code immediately reappears, the underlying component has not been fully resolved and you should recheck the part you serviced, inspect the wiring harness for a loose connector, or replace the related sensor. If the cycle completes normally and no fault is shown, your dishwasher is safe to return to regular use. To prevent the F24 code from coming back, schedule a monthly check of debris filters, drain lines, door gaskets, and supply hoses — the vast majority of repeat-fault service calls trace back to gradual buildup that could have been cleared in five minutes.
Frequently asked questions about Bosch F24
Is it safe to keep using my dishwasher while F24 is showing?
No. The control board has paused the cycle specifically to prevent further damage. Continuing to run the appliance can compound the issue and turn an inexpensive DIY fix into a major repair.
Will resetting the appliance clear the F24 code?
A power-cycle reset (unplugging for 5–10 minutes) may silence the code temporarily, but if the underlying fault is still present the code will reappear on the next cycle. Always perform the diagnostic repair above rather than relying on a reset alone.
How much does a professional charge to fix this?
In most U.S. metros, a licensed appliance technician charges between $120 and $300 for a diagnosis-plus-repair visit on this type of fault, with the higher end reflecting parts replacement. If the steps above resolve the issue, you'll typically save the full service-call fee.
