Bosch dishwashers are reliable, but when an E-code appears it points precisely to the subsystem at fault.
Water Supply & Drain
- E15: Water in the base pan — anti-flood float tripped.
- E24: Drain blockage — clean the filter and hose.
- E22: Filter clogged.
Heating & Sensors
- E09: Heating element fault.
- E01–E02: Electronic/heating circuit fault.
What To Do First
Most E15/E24 faults are debris-related, not electronic.
Fix: Clean the filter, check the drain hose, and clear the base pan before calling out.
