Blocked exhaust hose (vented dryers only)
Resolution
Check the air exhaust hose to make sure that warm air can pass through properly
Time: 5 min
Check that the air exhaust hose is not blocked or folded in half (only with exhaust air dryers).

Warning: If the hose is blocked or folded, drying efficiency will be decreased, resulting in longer drying times, higher energy consumption or the heater may stop working.
