The E07 error on your Bosch dishwasher points to a fault with the drying fan — specifically the Zeolite or Crystal Dry system on models that have it. Try a 30-second breaker reset first; if it returns, Bosch’s own guidance is to call out a technician rather than open the machine.

Error code E07
Meaning Drying fan / Zeolite system fault
Severity Medium-high — limited DIY scope
Time to fix 5 min reset, otherwise technician
Tools needed None for reset

What the E07 error means

Higher-end Bosch dishwashers use Zeolite or Crystal Dry technology — a small fan circulates air over a chamber of zeolite mineral that absorbs moisture and releases heat to dry dishes. If the fan motor stalls, the wiring fails, or the airflow is blocked, the control board logs E07 and stops the cycle. Cycles will still wash, but drying performance is gone until it’s fixed. On models without Zeolite, E07 doesn’t appear.

Common causes

  • Zeolite drying fan motor failed
  • Wiring fault between the fan and the main control board
  • Airflow blocked by debris in the drying duct
  • Control board fault commanding the fan incorrectly

How to fix the E07 error

  1. Cut power at the breaker for 30 seconds. Bosch’s official first step for E07 is a 30-second mains-side reset (not just unplugging at the wall). Flip the breaker, wait, flip it back, and run a short cycle.
  2. Run a short cycle without the rinse aid / drying option. If the wash phase completes cleanly with drying disabled, the fault is confirmed in the drying system rather than the wash circuit.
  3. If E07 returns after the breaker reset, Bosch’s published guidance points users to service rather than further home troubleshooting. The fan motor and Zeolite chamber are not designed for owner-serviceable access — opening the side panel risks damaging the chamber. Call a qualified Bosch technician.

FAQ

Can I still use the dishwasher with E07?
Often yes — wash cycles will run, but dishes won’t be properly dried. Some users carry on with the towel-dry workaround until a technician can attend. Don’t ignore the code long-term as the underlying fault may worsen.

Why does Bosch tell me to call a technician for E07?
The Zeolite chamber is a sealed unit and the drying fan sits behind multiple panels. Opening it without training can damage the chamber or void the warranty, which is why Bosch’s documentation skips the DIY repair steps for E07.

Is E07 covered under warranty?
Likely yes if the machine is within Bosch’s warranty period — Zeolite systems have a longer parts warranty on most current models. Check your warranty card before paying for a callout.
