The problem may be the
dehumidifier - or other parts
of the entire installation
(airtightness, hygrostat ...).
1. Check that the fans are moving air.
If not, replace the broken fan.
2. Check that the rotor is turning
as intended.
If not, replace the gearmotor.

is warmer than the inlet.
4. Check that the regeneration air outlet is warmer
than the inlet by approx.
40-60 °C depending on temperature conditions
of inlet.

is approx. 4,5A.
If fans and rotor are working, replace the
heating element.
