I have a duet ht frontload. It will get to about 12 minutes into a cycle with water in. Then it will flash an fh code and drain.

fh code can be caused by a dirty airtrap. small part back of tub near bottom. it is some what opaque, if it looks dirty, it probably is. can be replaced or cleaned by using vinegar or pool acid. use a plastic pail mix pool acid and water (not very much, just enough to cover part) drop in part walk away for an hour. use gloves to remove part rinse, use a bottle brush if necessary and reinstall. neutralize acid by diluting with water and adding a little baking soda before dumping into a toilet or sink. pool acid will eat metal, concrete, your skin, etc.
Airtrap has a tube that attaches it to the flow control, if it is clogged, air pressure can not be created, and it is what the sensor uses to tell the control unit if water is indeed entering machine.
this part is never mentioned in troubleshooting.

It is hard to tell from here. Sitting on my perch without my meter, does not help. Tom
