The father in law has one of those Bosch dryers and the thing is a nightmare. It gets used about as frequently as the drying rack right next to it.
The thing is always clogging and giving esoteric error codes represented by symbols and numerals. It requires maintenance on a weekly or so basis. And this maintenance isn't just giving it a cleaning. You need to disassemble a decent portion of it.
I'm really torn about what to do for drying clothes in the winter.
