Bosch Dryer Error Code E24
E24 is one of a group of Bosch dryer codes that all report a fault in the electronics, and the machine stops to protect itself. Try one full power reset; if the code returns, it needs a technician, as there is nothing to clean or unblock behind it.
Common causes
- Main control board failure
- Damaged wiring or a loose connector in the control circuit
- Power surge or voltage irregularity damaging the electronics
- Heat or moisture damage to the control electronics over time
What to check, in order
- Switch the dryer off and unplug it (or switch off the breaker) for at least 30 seconds, then restore power and try a short programme.
- Note exactly when the code appears, straight at switch-on or part-way through a cycle, and tell the technician.
- Make sure the dryer is plugged directly into a working wall socket rather than an extension lead, and check the breaker has not tripped.
- If the code comes back after the reset, stop using the machine and book a service visit. Bosch states electronics faults can only be fixed by a technician.
Clear the code and test
- Fix what the checks above found first. Clearing the code without fixing the cause only brings it back.
- Plug the appliance back in and restore its water supply if it has one.
- Run the shortest programme and watch the point where the code appeared before.
- If the programme finishes with no code, the fault is cleared. If the code returns, write it down before calling a technician — it speeds up the diagnosis.
When to call a professional
This code usually points to a faulty part, wiring or the control board on a Bosch dryer. Run the checks above to rule out the simple causes, then book a technician — and book one straight away if any of these apply:
- The code comes back after you have run the checks and a test cycle.
- You smell burning, see sparks or scorch marks, or the breaker trips.
- Water is leaking and you cannot stop it at the tap.
- The fix needs panels opened beyond what your manual describes, or a part tested with a meter, and you are not set up for that.
When you call, give the brand, the code E24, your model number (on a label inside the door or on the back) and the checks you already ran. It shortens the visit.
Repair or replace?
This fault is in professional territory: the fix usually means a major part or board-level work, and the labour adds up. If your machine is already well into its service life, get the repair quote first, then compare it with the price of a current equivalent model before you decide. Paying a large share of a new machine's price to repair an old one is rarely the better deal; replacing a machine over one cheap fault is wasteful too.

Parts are model-specific. Find your model number first — usually on a label inside the door, on the door frame or on the back — and match the part to that number before ordering.
