How it shows up ## What people describe when they call - “Two cycles to dry one load” - “Cycle time much longer than it used to be” - “Clothes hot but still damp” Two shortcuts ## Narrow it down before anybody arrives A description of the behaviour leaves a few possible causes. A code names the subsystem, and the model number says which parts to bring. Either one shortens the visit; both together usually settle it.

[ All models ](https://esbosch.djwp.xyz/models/) In more detail ## About Bosch dryer taking too long ### The fastest diagnosis is the code A published code for the lint filter exists, and it is the first thing to look at. But most slow drying arrives with no code at all — the machine does not know its filter is sealed with residue, it only knows the load is still wet. ### Slower on purpose A vented dryer pushes hot wet air outside and pulls fresh air in. A condensation dryer has to cool that air, drop the water out of it and reheat it, over and over. It uses less energy and needs no duct, and it takes longer. Judge it against how it used to perform, not against a vented machine. ### Where the time actually goes - A lint filter sealed with fabric softener film, which looks perfectly clean - A secondary filter or condenser unit nobody knew existed - A moisture sensor coated with residue, reading the load wrong - Clothes arriving too wet from a washer that did not spin properly - A drum packed too full for air to move through it This article is based on: - Official manufacturer documentation - Internal repair procedures - Technician repair history - Company quality standards Before you book ## Questions about bosch dryer taking too long Considerably longer than a vented dryer — that is the trade for having no duct. What matters is whether it has got worse, not how it compares to the machine you had before. Classic airflow. There is heat but nothing carrying moisture away, and the load bakes rather than dries. A little. The machine warms and humidifies the space it is in, and a sealed closet gives it less to work with. Leaving the door ajar is free and sometimes noticeable.
