Prolem drying clothes

Whilst 'combos' will 'wash' a full load of clothes, they are not so good at 'drying' a full load. Since there must be a 'tumbling space' inside of the drum, into which the clothes can fall during the drying cycle.
In a 'nutshell' one 'wash load' equals 'two drying loads',
That's the price you pay for having a space saving 'combo' machine instead of having a 'washing AND a drying machine.
Add to that the fact that most 'combos' are 'condenser driers', as opposed to 'free flow outlet driers',
.
The consequence is that it takes far longer to 'wash and dry' a load of clothes in a 'combi' as oppose to two separate machines

Most all dryers, including combo washer/dryers, have an electric wire coil for a heating element.
I suspect yours has given up ( they usually break in two, stopping the electrical flow). You should need to have the element replaced.
Going to need to take the whole machine apart to fix this.
Be blessed.

did it stop running or just not drying with heat?

I also have this unit with the same problems. After lamenting on making a poor purchase decision, I found somewhat of a solution. Basically, water is not being expelled during the dry cycle. When I addressed this issue, clothes were MUCH more dry than before. Made a quick video demonstrating the fix: http://www.youtube.com/watch?v=8EhzuzSk2Ok

The drum bearing has perished this wild cause the noise and the brown spots on your clothes is probably the grease from the bearing

I am having the same problem on a WD9900A. The wash cycle works great. Spins fast and clothes are completely rung out. Dryer cycle heats up well. Fluffs and heats cloths. At some point during dry cycle water is injected on clothes and they end up sopping wet; much wetter than after wash. Filter is clear. Outlet pipe clear and functions well. Possible problem with dryer timer? Or washer timing kicking back on?

Your timer has gone bad and you need to replace the time. Best bet is to get a Technician out there but you can do it yoursel. It is behind the face plate where it counts down the time

I have a similar problem with the FE Code. All i have manage to ascertain is that if you set the spin at 400 it will complete the cycle

my Hotpoint dry will not dry my clothes. It will run for hours and the clothes still haven't dry just felt hot.
