14. Shutting down
!
Material losses
If the appliance is disconnected from the power supply,
it is no longer protected against frost.
f Only disconnect the appliance from the power sup-
ply for longer periods if you are also draining the
DHW tank.
If there is no usage of hot water for a long period of time, always
drain the DHW tank. See chapter "See 16.4, “Draining the tank”,
pg. 30".
The appliance can only be switched off by interrupting the power
supply.
f Pull the plug from the socket or disconnect the circuit breaker
to the appliance.
15. Troubleshooting
WARNING Risk of electrocution
Prior to all work on the appliance, turn off all power
to it.
f For work inside the appliance, remove the appliance cover
(See 16.1, “Removing the appliance cover”, pg. 29).
f If necessary, remove the upper section of the casing jacket
(See 16.2, “Removing the casing ring”, pg. 29).
Note
Refit the casing ring after completing the work. See 16.9,
“Fitting the casing ring”, pg. 31.
Note
Refit the appliance cover after completing your work. See
16.10, “Fitting the appliance cover”, pg. 31.
15.1 Fault table
Fault Cause Remedy
The appliance
switches off
unexpectedly
and does not
switch on
again.
Excessive pressure in
the refrigerant circuit.
The safety pressure lim-
iter has responded. The
compressor has been
switched off.
Eliminate the cause of the in-
crease in pressure in the refriger-
ant circuit.
Wait approx.5 to 15minutes for
the appliance to equalize the
pressure. Reset the safety pres-
sure limiter (See 15.2, “Resetting
the safety pressure limiter”, pg.
29).
The appliance is operated
outside the operation
limit. The ambient tem-
perature is higher than
the permissible value.
The safety pressure limit-
er has responded.
Ensure that the operation limit is
observed.
Wait approx.5 to 15minutes for
the appliance to equalize the
pressure. Reset the safety pres-
sure limiter (See 15.2, “Resetting
the safety pressure limiter”, pg.
29).
The compres-
sor switches off
unexpectedly.
The thermal load of the
compressor has been ex-
ceeded. The motor over-
load relay has responded.
Remedy the cause of the high
thermal load. Wait until the appli-
ance restarts.
