Check list - error codes related to overheating

General note regarding error codes related to overheating:
Before troubleshooting the electronic systems of the machine, examine the
dryer to determine if the airflow is normal.
Insufficient airflow due to over-filling the machine, lint-obstructed screens,
air passages and ducts, or improper exhaust venting are all possible cau-
ses of various errors.
Items concerning the necessary air flow
1. Check that the fresh-air intake to the room and the exhaust ducts/pi-
pes from the room are not clogged by lint/dust or blocked in any other
way.
2. Check that the dryer receives the necessary quantity of fresh air.
(See installation manual).
3. Check that the fresh-air intake preasure drop does not exceed 10 Pa
(applies only to air-intake duct kit, if installed - See installation manual).
4. Check that the pressure drop in the air outlet ducts does not exceed
the value printed on the data sheet in the Service Manual for the speci-
fic dryer. (Measurement is done with cold air (20°C/ 68°F).
5. Check that the air inlet screen on the rear of the dryer is not clogged
by lint or dust.
6. Check that the lint screen is clean and in good condition.
7. Check the door gasket and internal sealing against the drum are
defective/ missing/ dirty.
8. Check that the blower compartment and fan wheel have not become
blocked with lint or other debris.
9. Check that the fan wheel is in good condition, and that it is tightly
secured to the motor shaft.
10. Check for severely overloaded dryer. Remove some items as appro-
priate.
Items concerning gas connection
1. Check that the gas type corresponds with the dryer's data plate.
2. Check gas inlet and nozzle pressures.
