Bosch Dishwasher Error Codes
Bosch dishwashers show an E-code (or blinking numbers) when a wash can't complete. Here's what each means and how to clear it.
E15
Means: Water in the base pan triggered the anti-flood (Aquastop) float.
Fix: Tilt the unit back slightly to drain the base water, then dry the pan. Find and fix the small leak (often the tub or a hose) so it doesn't return.
E22
Means: Filter or drain blockage — poor drainage.
Fix: Clean the filter cylinder in the tub floor and clear the drain pump and hose.
E24
Means: Drain hose blocked or kinked.
Fix: Straighten and clear the drain hose; check the air gap or sink drain connection isn't clogged.
E09
Means: Heating element fault.
Fix: The flow-through heater has failed and typically needs replacement by a technician.
E01
Means: Electronic control fault.
Fix: Power down for 10 minutes to reset. A repeating E01 usually means the control module needs service.
E25
Means: Drain pump blocked or pump cover loose.
Fix: Remove and clean the drain pump impeller; make sure the pump cover is seated correctly after cleaning the filter.
FAQ
How do I fix E15 on a Bosch dishwasher?
E15 means the base tray has water and the float switch tripped. Tip the machine back to pour the water out, dry the pan thoroughly, and check for the leak's source before restarting.
How do I reset a Bosch dishwasher?
Press and hold the Start button for about 3-5 seconds until the display clears, or cut power at the breaker for 10 minutes. This clears most transient codes.
