Cycle reverse valve faulty
The cycle reverse valve could be faulty or broken. (see

Water inlet high temperature
The water inlet temperature has exceeded the set_install-
er (H) parameter value. Probable boiler presence on
same plant. At the third intervention of the pre-alarm, the
machine goes into alarm mode and blocks

156
Cycle reverse due to high
temperature of the pressing line
gas
This pre-alarm indicates the intervention of defrosting
due to cycle reverse without having respected the times
between cycle reverses. Cycle reverse has been triggered
by the pressing line gas high temperature partialisation
threshold being exceeded, set_factory (6)-set_factory (4)
= default 130°. This pre-alarm does not cause compressor
stop and does not have a limited number of interventions
57
157
Reading error of the DHW control
board remote probe.
This pre-alarm indicates a remote probe fault or a commu-
nication problem with the DHW control board. The alarm is
only active if the parameter (0)=2 or the parameter (8)=4 in
the menu with password = 30

158
Outdoor air temperature probe
reading error
This pre-alarm indicates an outdoor air temperature probe
fault when the DCP is present or the machine is in heat
pump mode.
