Zanussi Dishwasher|Electrolux Dishwasher A Alarms that stop the dishwasher Remedy
A1 Error Want of water Is the water open?| Does the water load solenoid valve work? Is the water feed flow a min. of 5 l/min? Is the water inlet filter clean? Is the load solenoid valve filter clean? Is the overflow inserted? Is the main board (ATM-PRES) CN2 connector correctly positioned? Do the tank/boiler pressure switches work properly?

C8 Error During rinse phase boiler doesn't empty Are the rinse arms clogged? Does the rinse pump work correctly? Is there water in the level sensor tube? Is there scale in the boiler? Does the boiler level sensor work properly?
C9 Error Automatic hood out of order See par. C1 - Alarm codes for automatic hood type dishwashers When the alarm C9 appears, to facilitate fault-finding another parameter providing a more detailed indication has been introduced. |
B1 Error Drain not efficient Has the overflow been removed? Is the water drain blocked? Is the drain pump blocked? Are the air trap and tank pressure switch clean? Is there a constriction in the drain tube? Is the pump breather pipe returning to the tank clogged or constricted? Does the tank pressure switch work properly? Is there a hole in the drain tube (only for versions with drain pump)?
B2 Error Overflow alarm Is the water drain blocked? Are the air trap and tank pressure switch clean? Does the tank pressure switch work properly? Is the load solenoid valve blocked? (E1 - LOAD_EV) Is the load solenoid valve relay stuck? (RL8 - LOAD_EV)
C1 Error Boiler temperature rise too fast Does the boiler level sensor work properly? The boiler could be empty Are non-original power resistances installed?
C2 Error Boiler temperature too high Has the boiler temperature been changed (btC - increased above 90°C)? Has the software alarm value been modified (bHi)? Does the boiler level sensor work properly? Is the boiler relay stuck (see RL2, RL3, RL4)? C3 Error Tank temperature too high Is the feed water above 60°C? Has the software alarm value been modified (bHi)? Is the rinse water temperature too high? Is the tank relay stuck (RL5 - TUB_HEAT)?
C4 Error Tank temperature sensor out of order Is the temperature sensor broken or disconnected (NT1)? Is the temperature sensor connector correctly inserted?
C6 Error Boiler temperature sensor out of order C7 Error Boiler temperature sensor out of order C10 Error Rinse temperature sensor out of order C11 Error |

E1 Error Communication error Is the connection between main board and control panel correct? Are the connectors correctly connected? Are connector contacts clean? E2 Error Tank temperature low Does the tank heating element work properly? Are the connectors correctly connected? Are the dishwasher feed voltage and current correct? Is the relay RL5 on the board disconnected or faulty?
E3 Error Boiler temperature low Does/do the boiler heating element/s work properly? Are the connectors correctly connected? Does the possible remote control switch connected to the heating element work correctly? Is there power at the remote control switch input terminals? Does relay RL2 on the board work properly?

F21 Error Water softener operation errors This alarm appears in case of malfunctioning in the continuous water softener. To reset errorF21 it is necessary to disconnect and reconnect the main power supply to the machine by means of the main switch on the external power board.
F22 Error Communication errors between the mother board and softener board This alarm appears in case of problems in communication between the mother board and water softener board; check the connection between mother board connector J1 and water softener connector ST8.

DISHWASHER WITH INCORPORATED CONTINUOUS WATER SOFTENER Dishwashers with incorporated continuous water softener have a continuous softener in the water circuit. By means of special resins, this device removes the calcareous substances from the feed water, supplying decalcified water for washing. To activate the continuous water softener, set the parameter SER (in the HCP family) to the value 9 or the value 11 if the water softener board is connected to the LK485 board.
For the continuous softener to work properly the resins must be regenerated periodically with a frequency depending on the hardness of the inlet water, the number of wash cycles carried out and the max. hardness set with the parameter SrU (in the CFG family)Unlike conventional water softeners, this continuous softener does not require machine stops for regenerating the resins. To regenerate the resins it is necessary to put coarse salt in the special container located in the dishwasher. In particular, the salt container must be filled when the dishwasher is used for the first time and whenever the messages SAL 0 or SAL END are displayed at the start or end of a wash cycle. The salt container holds up to 1.5 kg of salt.
| | | | | |
CAUTION: use only coarse salt with a NaCl purity grade of 99.8 %. The use of salt with a lower
purity grade may cause the sale container filter to clog and the water softener to malfunction.
IMPORTANT: The messages
SAL 0 or SAL End may appear for several wash cycles even after topping-up the
salt, as the salt must circulate in the entire system. Correct operation of the dishwasher is not,
however, affected.
The number of regeneration cycles performed can be checked by consulting the parameter
nrE in the Cnt family of counters.
nrE only counts regeneration cycles carried out with the salt container adequately filled;
there is another counter, rES (in the Cnt family) that indicates the number of regeneration
cycles done without salt.
If the parameter
SrU is set to the value10, according to the factory setting, the water softener outlet
water hardness can vary between 3°fH - 10 °fH/ 1.7 °dH - 5.6 °dH / 2.1 °cH - 7 ° cH.
AUTONOMY OF A COLUMN OF RESINS ACCORDING TO THE CHANGE IN INLET
WATER HARDNESS, WITH OUTLET WATER HARDNESS OF 10 °fH / 5.6 °dH /7 °cH
(SrU =10 according to the factory setting).
Alarms that don’t stop the dishwasher for models with incorporated
continuous water softener
If alarm F21 or F22 appears, the machine indicates it on the display at regular intervals and
auto-configures itself in the same way as a machine without water softener.
Resin regeneration cycles are not performed and the column used for filling is always
the same (column B).
Alarm F21 is reset when the machine is switched off and on from the mains switch
(only if the causes that generated it have been eliminated).
Alarm F22 is reset when the machine is switched off and on from the user interface or from
the main switch(only if the causes that generated it have been eliminated).
