I Bought a washer and dryer from Trail Appliances via online chat. I also paid to have them installed and the old ones hauled away. From the very first load the dryer has been displaying a code that means either the vent is plugged, or there are too many bends (restricted air flow).
It had been many years since we had the vent cleaned so we believed it was plugged and had someone come in to clean it. However, since the cleaning the code still shows up after every load.
Since the vent behind the wall is a straight line to outside, this could only mean the installers did not hook up the vent hose very well (too many bends or possibly even crushed).
After the first call to Trail I was told they'd talk to the installation department and get back to me. They never did. On the second call I was told they would not do anything about the install because I didn't pay for their "premium" install which I guess means their "basic" install means maybe things will work properly or maybe they won't. I was told I'd have to call the manufacturer who I'm betting will also tell me they don't deal with poor installs.
