    Service 1. Safety rules manual Safety rules Programming is only to be carried out by qualified personnel. High voltage on the printed circuit board. IMPORTANT SERVICE NOTE! Continuity and resistance measurements suggested by the procedures in this manual require that power to the dryer be disconnected, and that the device whose resistance is being measured be disconnected from all circuits that might affect the accuracy of the measurement. Note! It is very important that the board is protected from static electricity Remember! • Always use an earthed wrist strap. • Without the antistatic wrapping the board is unprotected. • Keep all subjects away from the board which can cause static electricity. • Subjects like plastic, foam plastic, nylon, or cellophane wrapping are all big dischargers of static electricity. • Static electricity can not always be felt, heard or seen. • Board components can be damaged by static electricity under 100V. • Static electricity can not be felt, heard or seen till the voltage reaches 2500V. 487 05 40 31...

    Service 12. Error codes manual 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 causes of various errors. Items concerning the necessary air flow 1. Check that the fresh-air intake to the room and the exhaust ducts/pipes 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.
