Dishwashers: E10 error code by brand
On Bosch and Siemens dishwashers E10 points to the drying system, not the water supply. Other brands use the code differently.
| Brand | Code | Meaning (from the maker) | Region |
|---|---|---|---|
| Bosch | E10 (E:10) | Fault in the drying system: the Zeolite (CrystalDry) chamber heater. | USA |
| Siemens | E10 (E:10) | Fault in the dishwasher's drying system: contact Siemens service. | UK, Ireland & Europe |
Safety. Switch the appliance off at the wall or breaker before you open any panel. Heaters, pumps and control boards run on mains voltage: replacing them is a job for a qualified technician.
Why the same code means different things
Error codes are not standardised. Each manufacturer writes its own list, and even one brand can change it between model generations. That is why every page here names the brand, links the maker's own support page and shows the date we checked it. If your brand is missing, we have not yet found an official meaning: check the manual (often in a pocket on the back or inside the door, or on the maker's website by model number).
