SELF-DIAGNOSIS
The machine is equipped with a self-diagnosis system that can detect and signal a series of malfunctions.
CAUTION! Turning the machine off and then back on resets the signal, which will appear subsequently
only if the problem has not been resolved. If the signal persists, contact a qualified technician.
Message displayed
Anomaly or alarm discovered
E01
Rinse not performed (Only versions CRP-SP). This signal appears at the end of
the cycle if the working level in the tub is not correctly restored. Check whether the
plumbing connections are correct, and that the water supply cock is open. If the
problem persists, contact technical service.
E02
Water drainage anomaly. Water does not drain or drains abnormally. Check to see
if the overflow has been removed. Check the drain tube is not bent or crushed, and
that none of the filters are clogged. Run another drain cycle. If the problem persists,
contact technical service.
E03
Boiler temperature reset anomaly. The boiler temperature reset has not occurred
within the time limits set forth in the wash cycle. Turn the machine off and then back
on and run another cycle. If the problem persists, contact technical service.
E04
Tub filling time out: the tub has not filled.
Check whether the plumbing connections are correct, and that the water supply cock
is open. Check the presence of the overflow. If the problem persists, contact
technical service.
E05
Tub thermometer anomaly. (Probe open) The machine does not measure the
temperature in the tub. Turn the machine off and then back on. If the problem
persists, contact technical service.
E06
Tub thermometer anomaly. (Probe shorted out) Interrupt the programme in
progress, and shut off the dishwasheril. Turn it back on after a few minutes and start
the cycle again. If the problem persists, contact technical service.

Boiler temperature too high.
ESF
Electromechanical safety: the safety thermostats of the boiler or tub have tripped,
or the tub safety pressure switch has intervened. Contact a technical service centre.
ESL
Incorrect tub level: the tub pressure switch has detected a level of water in the tub
that is too high or too low. Contact a technical service centre.
E22
Tank heating time out: fault during the heating of washing water. Turn the
dishwasher OFF and back ON again; in case the problem persists contact an
authorised service centre.
