never reached in this cycle.
Possible Faults:
●
Bad temperature probe.
●
Wiring to electrical or steam heating relay has
failed.
●
Electrical heating elements or steam valve is
broken.
NOTE: If the cycle aborted, it may be due to a
temperature sensor error.
The control did not sense any pulses or the control
sensed wrong pulses from the rpm sensor.
Possible Faults:
●
Rpm sensor is broken.
●
Distance from rpm sensor to pulley is too large
(>2mm).
●
Bad motor.
●
V-belt is broken.
●
Problems with the inverter.
●
Wiring connection is bad.
An error occurred at the end of a spin stop or during
coast down, where the rpm sensor suddenly failed to
give output pulses.
Possible Faults:
●
Rpm sensor failure.
●
