the drying position, the furnace
fan and the pre-cleaner are
functioning, otherwise the dryer
does not respond.
The earth leakage circuit
breaker trips
The functioning of the dryer
lights during the drying process
is abnormal or no power is

Note!
If you have reset any of the motor protection relays, and the relay trips again immediately after the
next start-up attempt, and this happens during the warranty period, contact the manufacturer's
maintenance workshop and agree on the possible remedy measures. The fault is either in the motor
protection relay or the motor connected to it. Therefore it is advisable that the manufacturer's
maintenance technician or the local authorised electrical workshop comes and finds the cause of the
fault.
