What a Bosch dryer is like to work on
Bosch heat-pump dryers need no exhaust duct, which is exactly why they end up in condominiums and converted spaces where venting was never possible. The condenser takes on the work the duct would have done, and like a duct it fouls — quietly, with no error, over months.
Model lines we service
What we open one for
Cycles getting longer and longer
The condenser fouling with lint. No error is shown, which is why this is usually reported as "it has always been slow".
Not heating
The heat-pump circuit or its controls. Not a heating element — these do not have one in the sense a vented dryer does.
Water collecting where it should not
The condensate pump or its float. The machine collects the water it removes, and that path can block.
Is there a code on the display?
We have written out what each Bosch code reports, what causes it, and whether it needs anybody at all — several of them are not faults.
Bosch error codesParts and what they cost
Obtainable without long waits. The condenser is maintenance rather than a part, and it is the first thing we check on a slow machine.
Most dryer jobs land between $150 and $350, parts included, and the $150 minimum service call is part of that rather than on top of it.
When to call Bosch instead of us
New-build kitchens in this county are full of Bosch that is still inside its manufacturer warranty. Check before booking us — if it is covered, that repair should not cost you anything.
Answered
- It has never dried as fast as my old dryer.
- Heat-pump dryers do run longer cycles than vented ones by design — that is the trade for needing no duct. But if it has got noticeably worse, the condenser is fouled and cleaning it usually brings it back.
