TSE-P 04.00 EB
Pressure chamber blocked
(water level does not vary for at least 30 sec. during
drum rotation)
Door open
(door delay interlock does not close after 15
seconds)
Problems with door closure
(door open during cycle for more than 15 sec. or
door closed after cycle for more than 3 min.)
TRIAC which powers the door interlock faulty
(incongruency between status of door interlock
"sensing" circuit and status of TRIAC)
"Sensing" circuit of door delay interlock faulty
(input signal to microprocessor always 0V or 5V)
"Sensing" circuit of door delay interlock triac faulty
(input signal to microprocessor always 0V or 5V)
TRIAC which powers the motor short-circuited
(TRIAC short-circuit cut-out activated or motor
speed more than maximum speed)
No signal from tachometric generator on motor
(no signal after maximum time)
"Sensing" circuit of motor TRIAC faulty
(input signal to microprocessor always 0V or 5V)
Relays contacts sticking
(voltage on "sensing" circuit when the relays should
be open)
Motor circuit open

Heating phase Pressure switch hydraulic circuit; pressure switches,
skipped motor drive belt broken
