installation
Hey, fellas.
It's been my experience that if a machine works miserably within the first year of it's life, it's almost always an installation issue. Something's not right about how it's installed.
If it's vented, the vent hose is most likely kinked. If it's a condenser dryer, perhaps the inlet valve for the cold water was not plumbed correctly.
In any event, 4 hours to dry is wrong, and my crystal ball tells me it's not the machine, but the installation which is to blame. Perhaps adequate space around the blower opening was not allowed. In any case, I'll bet you a dollar (ok, a Euro) that the machine is fine.
I have an Equator EZ1000 washer/dryer and it works wonderfully and drys properly in about one hour.
Check to see if both legs of the power are working. In USA we use two big fuses on our 240 volt machines...one can go bad and the machine will still run, but won't heat properly.
Perhaps your machine is not getting it's full operating voltage.
Good luck fixing it and do let us know what was the problem.
