Bosch dishwashers fault codes
Every Bosch dishwashers fault code we have documented, with what it means. Pick yours to see causes, checks and the parts involved.
● 15 codes documented
Bosch uses 15 fault codes on its dishwashers, shown on the display when the machine stops — among them E0, E1, E12, E14, E15. Each one points to a specific part: on this page you find them all, with what they mean.
How to read the code on the display
On most Bosch appliances the code appears on the display when the cycle stops, or is spelled out by a sequence of blinking lights.
Write the code down before switching off: many machines clear it when unplugged, and without the code the fault has to be found from scratch.
