Bosch Dryer E24 Means the Self-Check Found an Electronics Error

What E24 means

The dryer stops or refuses to run and the display shows E24. What happened behind the scenes is that the machine ran its own internal self-check while operating and found something wrong in its control electronics. The code is deliberately broad: it tells us the electronics tripped a check, but not which board, wire or connection is responsible, so the cause has to be narrowed down with testing.

Common causes of E24

Control board part that has failed (the most likely finding, so it is tested first)
Internal wiring that is damaged or has a poor connection
Interference from a power surge or an outage that disturbed the electronics

✓ One safe check you can try

1. Switch the dryer off and turn its breaker off, because the terminals can stay live until the breaker is off. 2. Leave it off for two full minutes, then switch the breaker back on. 3. Start a short cycle. If E24 shows up again right away, the electronics problem is real and not a one-time glitch. Stop there and call us.

! Why to stop there

E24 does not name a part, so swapping a board on a hunch is an expensive way to learn you guessed wrong.
Probing control electronics before the unit is confirmed dead is a genuine shock hazard.
A wrong part swap can hide the true cause for a while, and the problem comes back later after more wear has done more damage.
Opening the control housing is one of the easier ways to affect manufacturer coverage, so check your terms first.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

E24E24 questions

Can I narrow down E24 on my own?

Not reliably. The code covers several possible parts, and finding the real one takes diagnostic tools and a technician who can test the circuits with the power isolated.

Is it okay to keep drying clothes while E24 is showing?

We would pause until it is checked. Electronics that report an internal error can act unpredictably mid-cycle, and a dryer is not an appliance to gamble with.

Will you tell me the price before replacing anything?

Yes. We give you a written price once we know the cause, and you approve it before work begins. The repair carries a 30-day workmanship warranty.
