6 FLASH CYCLE
– NOT FILLING
Display pattern:
•
6 flashes then a short pause - repeated.
Electronic check
and action:
•
This checks that the water in the tank cools when the inlet solenoid
valve is switched on.
•
This is a recoverable error. This checks that the water in the tank is
cooled by when the inlet solenoid valve is opened. If the water pressure
is within the specifications (5-50psi), the inlet solenoid should not be on
for more than a few seconds.
Probable causes:
•
Mains water pressure problem or the mains water stop valve is closed.
•
Inlet solenoid valve failure.
Action required:
•
Check the mains water supply. (Note: Temporary loss of water pressure
can occur in certain sites
– particularly when various machines are
plumbed to the same mains water supply.) If the water supply is
restored machine will recover automatically.
•
NOTE: If the water supply is the problem, ensure that this is
rectified or this error will re-occur.
•
If there is no problem with the mains water supply, check that the inlet
solenoid valve is working.
3.6. M AINT ENANCE:
Marco machines have been designed to give many years of trouble free service. Marco Beverage
Systems manufacture and test to ISO9002:2000 standard. The only regular maintenance required is
occasional de-scaling.
Descaling Procedure:
•
Isolate machine from power supply.
•
Isolate machine from water supply.
•
ALLOW TO COOL COMPLETELY!
•
Drain water from machine.
•
Remove all lids.
•
Remove as much scale as possible by hand, paying particular attention to level probes (White
plastic with steel tab). Be very careful not to damage any attachments.
•
Use ScaleKleen, Marco part No. 8000270 or similar. Follow instructions carefully.
•
Thoroughly clean and flush the machine before re-use.
•
Follow installation and first time operation instructions
3.7. CLE ANING:
The exterior of these machines may be cleaned with a damp cloth and a light detergent. Do not use
abrasive cloths or creams, as this will spoil the finish of the machine. Do not use a water jet or spray.
Beware of accidentally operating the draw off tap or push button when cleaning the front of the
machine.
3.8. LIM ESCALE:
In common with all water boiler manufacturers, service calls resulting from limescale are not covered
by warranty. Fitting a scale reducer is recommended, especially in hard water areas. This can
reduce the build-up of scale but may not stop it altogether. The frequency that descaling is required
depends on the local water supply; hard water areas need more attention. A scale reducer can
reduce the build up of scaling, but may not stop it altogether. Descaling of the machine should ideally
be carried out by qualified service personnel.
