# Bosch dryer heating repair

### Air before heat

A condensation dryer cools its own exhaust, drops the water out of it and reheats what remains. Nothing goes outside. So the air path matters more than on a vented machine and there is more of it to block: the lint filter, a secondary filter, and on some models a condenser unit that needs rinsing.

The classic is a filter that has been rinsed for years and never scrubbed. Fabric softener leaves a film that seals the mesh; it looks clean, holds water when you pour it over, and passes almost no air.

### Then the circuit

When the heating circuit itself has gone, the machine says so with a code, and the manufacturer’s own guidance is that it is not a home repair. We agree with that one — it is a heating element and its safety devices in a sealed cabinet, and the failure modes are not forgiving.

### After a storm

Electronics codes on laundry after a power cut are common here, and a fair share of them clear with the machine unplugged for a few minutes. If it comes back after that, it means something.

What this involves

Filters and the air path first

Heating circuit and sensors

Condensate drain and tank

Every filter

There is more than one, and the secondary one is the one nobody knows about. A mesh sealed with fabric softener film looks clean and passes almost no air.

Where the water goes

A condensate hose kinked behind a stacked pair, or a tank that has never been emptied because nobody knew it was there. A dryer that cannot drain cannot dry.

The heating circuit

Measured. The manufacturer publishes a code for it, and that code means a technician rather than a home repair — this is the one circuit on the machine we would ask you not to open.

A real load, timed

Signed off against a load that actually dries in a normal cycle, not against an empty drum that gets warm.
