Clean the door net filter. If it comes back, it needs a visit. ### Which filters does E4 refer to on an Asko dryer? The net filter in the door and, on heat-pump models, the foam heat-pump filter behind the lower cover. Clean both before assuming anything else. ### Why does Asko list E4 as a control unit failure? Its table pairs E4 with the control unit even though the first instruction is to clean the filters. If clean filters do not clear it, the control is the next suspect. --- **[Read on the site: Asko dryer showing E4 | DryerRepair.center](https://dryerrepair.center/error-codes/asko-e4/)** **[Book a visit with DryerRepair.center](https://dryerrepair.center/schedule/)**
