Quick answer
Bosch's opened US dryer error page lists E24 with E08, E09, E25, E28 and E90 as an electronics fault that can only be eliminated by an authorized technician. Bosch's opened Germany and Egypt E24 dryer pages give the same service boundary, with the German page also mentioning a device-electronics or sensor fault. Because the dryer model and market are missing, confirm the complete display and name-plate identity before using any model-specific instruction. Do not transfer E24 from a Bosch dishwasher, washer, or another dryer platform; do not open the cabinet, enter service mode, take live measurements, or order a board or sensor from the code alone. If there is smoke, burning odor, arcing, unusual heat, cord damage, or a repeated breaker trip, leave the dryer off and obtain qualified service.
Work through in order
Diagnostic checks
Use only checks that match the exact appliance or system and its official guide.
-
Check 1
With the dryer stopped and cool, photograph or transcribe every display character exactly, including the leading E, number, punctuation, spaces, alternating segments, flashing indicators, and beeps. Do not restart the dryer merely to reproduce the message.
Expected result: The display is exactly E24, contains extra digits or punctuation, alternates with another code, or cannot be read reliably.
Next step: Keep the photo or transcription for support and compare it only with documentation matching the complete dryer model and market.
Stop if: Do not enter service mode, repeatedly clear the code, or run cycles just to obtain another display.
Why this matters
Why: Bosch publishes separate dryer entries for E24 and other displays. A partial or visually similar message cannot select the correct platform or a component diagnosis.
-
Check 2
Read the complete Bosch dryer model number from its ordinary name plate without removing panels or moving the appliance, and record the country or market where it was purchased.
Expected result: A complete model and market are available, only a partial model is available, or the market remains unknown.
Next step: Use the complete model with Bosch support and provide it with the exact E24 record when arranging service.
Stop if: Do not substitute a washer, dishwasher, heat-pump model, or another market's manual for the identified dryer.
Why this matters
Why: Bosch routes manuals and support by model. An incomplete identity cannot prove which display convention, owner-level action, or service documentation applies.
-
Check 3
While the dryer remains off, record only user-visible context: whether the drum was turning or heating, the cycle and stage when E24 appeared, whether controls respond, whether the display returned after a normal power-off, and whether the load was removed safely. Do not open the cabinet or perform live electrical tests.
Expected result: E24 appeared at start-up, after tumbling or heating began, after an interruption, with an unresponsive control panel, or on every start.
Next step: Give Bosch or a qualified appliance technician the model, market, display record, cycle stage, and observed response; keep the dryer out of service until advised.
Stop if: Do not order a control board or sensor, remove panels, bypass an interlock, or use a multimeter on the energized dryer.
Why this matters
Why: The timing helps an authorized technician reproduce the complaint, but it does not identify a specific electronics module, sensor, relay, wiring fault, or heating component. Bosch classifies E24 as a service-level electronics fault on the opened dryer pages.
-
Check 4
From outside the appliance, check for smoke, burning or melting odor, arcing, unusual heat, a hot or damaged cord, water near electrical parts, or a circuit breaker that trips again. Do not energize the dryer when any of these signs are present.
Expected result: The dryer is cool and dry with no warning, or a hazard sign is present.
Next step: For a nonhazardous recurring E24, leave the dryer off and arrange authorized Bosch service. For a hazard, isolate the appliance and obtain urgent qualified appliance or electrical help.
Stop if: Do not repeatedly reset a tripping circuit, run a heat cycle to test it, or open the rear, top, or control enclosure.
Why this matters
Why: A safety symptom takes priority over the E24 interpretation and makes powered testing inappropriate. A dry exterior does not make a Bosch electronics fault user-repairable.

Decision map
Find the observation that best matches what you see, then follow the next safe action.
-
PATH 01Next step
What you see
The complete display is E24, the appliance is confirmed as a Bosch dryer, and there is no smoke, heat, odor, arcing, water, or repeated breaker trip.
Do this next
Book Bosch or qualified appliance service with the full model, market, display photo, cycle stage, and control response; do not choose a part from E24 alone.
Why this path and its safety boundary
Why it matters: This matches the opened Bosch dryer E24 support path, which treats the condition as an electronics fault requiring authorized or experienced service rather than a lint, condensate, or user-cleaning remedy.
-
PATH 02Next step
What you see
E24 is displayed but the model, market, or complete display format is missing or cannot be matched to Bosch documentation.
Do this next
Stop code-specific troubleshooting and provide Bosch service with the complete name-plate identity and exact display record.
Why this path and its safety boundary
Why it matters: The public Bosch dryer pages support the electronics-fault/service boundary, but they do not prove a generation-specific reset, diagnostic sequence, or compatible part.
-
PATH 03Next step
What you see
The photo shows a different code, a dishwasher or washer display, or only a maintenance prompt such as a filter or condensate message.
Do this next
Preserve the exact display and use only the manual and Bosch support page for the confirmed appliance and market.
Why this path and its safety boundary
Why it matters: E24's dryer electronics meaning no longer applies. Bosch publishes separate appliance and message branches, so cross-platform mapping would create the wrong repair path.
-
PATH 04Next step
What you see
E24 is accompanied by smoke, burning or melting odor, arcing, unusual heat, cord damage, water near electrical parts, or repeated breaker trips.
Do this next
Leave the dryer off, keep clear of damaged or wet electrical areas, and obtain urgent qualified appliance or electrical help.
Why this path and its safety boundary
Why it matters: The safety condition overrides code interpretation and makes further operation inappropriate.
Helpful context
Understand the symptom
What Bosch E24 means on a dryer
The opened Bosch US dryer error list places E24 in the electronics-fault group and says an authorized technician is required. Bosch Germany describes E24 as a fault in the appliance electronics or a faulty sensor and directs the owner to factory service; Bosch Egypt likewise says E24 is an electronics fault requiring an experienced engineer. These are dryer-specific pages. They do not support importing the Bosch dishwasher E24 drain meaning, or diagnosing a particular board, sensor, wiring harness, or other part from the code alone.
Why the model and complete display still matter
The task does not provide a complete Bosch model, purchase market, or display photo. Bosch's US support guide asks owners to have the dryer model number ready for assistance and its dryer error page routes owners to the owner manual by model. Record the full model and the entire display before applying any additional instruction. The opened sources do not establish a universal E24 reset sequence, service-mode operation, or replacement-part fit across Bosch dryer generations and regions.
When checks do not resolve it
Need a professional?
Arrange authorized Bosch or qualified appliance service for recurring E24, an incomplete or unmatched model/market, an ambiguous display, or an E24 that returns after any exact-model user instruction. Bosch's opened dryer pages classify E24 as an electronics fault that requires an authorized or experienced technician. For smoke, burning or melting odor, arcing, unusual heat, cord damage, water near electrical parts, or repeated breaker trips, leave the dryer off and seek urgent qualified appliance or electrical help.
