My dryer did the same thing. I cleaned all the vents thoroughly, if you are unable to clean inside where the vent screen is try this. remove lint screen, using tape or rubberband attach a empty paper towel roll to the end of your vacuum crevice tool. Also at the 99 cent store I purchased a appliance brush to loosen any lint inside before vacuuming. The brush works better then the one I purchased from Home Depot for $15.
Vacuum the inside of the dryer, be sure to vacuum the very back inside and around the door.
This is the tricky part now.
The dryer flex hose actually has to be set just right. If the placement is incorrect you will get the error codes, dryer turns off after mins etc.
Here is a Flex hose tip video. Hope this is helpful
