Ok as you have E00 then the electronics are not picking up a fault on the electrical side of the dryer. So as the electronics side is fine then the fault is on the sealed system side.
The main problem we see on these is the condenser chamber blocks up with dust and fluff and restricts the air flow through it which causes issues with the system.
So as you say there is some heat then i think the compressor is fine so its pointing towards a blocked condenser chamber.
But this isnt the easyist thing to clear. As what we do is replace the complete base unit which comes complete as the sealed system.
But if you are handy at repairs then what you can try is fully strip this down to the base. So you need to remove the top, side panels back panels motor and all the wiring and then the front panel.
Take pictures as you go along.
So then you will be left with just the base.
There on the left is the condenser. You will see this all the way through.
Take it out side and get a hose pipe and blast it through the condenser chamber and clear out any fluff blocking it up in there.
Once clear refit all the parts and retry it from there and hopefully this will cure it. Now it is a full strip down and will take a few hours to do but if this works then it will save a lot of money as the bases are very expensive on these.
If you need the service manual for this to strip it down then let me know and i can dig it out for you.
