E10 is tied to the Zeolite/CrystalDry chamber-heating path on compatible Bosch dishwashers. Confirm the model before applying this interpretation.
On supported Bosch dishwashers, E10 is associated with Zeolite / CrystalDry chamber heater fault. That description identifies the system path the control is concerned about; it does not, by itself, tell you which component to replace.
What E10 narrows down
The technical anchor for this record is Zeolite / CrystalDry chamber heater fault. Keep that meaning tied to the exact dishwasher platform. The code identifies a condition detected by the control system, while the full model number and the behavior immediately before the warning help determine the actual repair path.
What you may observe
- CrystalDry performance may drop
- dishes can finish wetter than normal
- the program may interrupt around the drying stage
- E10 can remain after a routine restart
What may be behind the warning
- a fault in the CrystalDry/Zeolite chamber heater
- wiring or switching problems in the chamber-heating path
- a model-specific temperature or heater-control fault
Checks that stay on the safe side
- Record E10 and the full model/E-Nr first.
- Use one external reset only where Bosch specifies it.
- Do not open the Zeolite chamber or attempt internal heater measurements.
When to stop
Stop use for overheating, smoke, a burning odor, or visible electrical damage.
If the code returns
A returning E10 needs diagnosis of the CrystalDry chamber heater and the circuitry that supplies, monitors, and controls it. Model identification is critical because the drying hardware varies across Bosch families.
Model note
Use the complete Bosch E-Nr/model number from the rating label. Do not assume that another Bosch dishwasher with the same exterior design uses the same internal components or diagnostic sequence.
FAQ
No. The verified meaning used here concerns the CrystalDry/Zeolite chamber heater, not routine descaling.
Yes, reduced drying performance is a plausible symptom when the chamber-heating path is not working normally.
No. Keep homeowner checks external.
Because Bosch uses different drying architectures across model families, and the code must be interpreted against the correct platform.
Bosch dishwasher service in San Francisco
Still seeing E10 on your Bosch dishwasher?
If the warning remains active or comes back after the appropriate safe checks, request Bosch dishwasher diagnosis in the San Francisco Bay Area. Include the full E-Nr, the exact code, what the dishwasher was doing when it appeared, and your service ZIP code.

Model compatibility: Bosch reuses codes across series and model years, so E10 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
