M2 Machine Operation

Press On/Off Key for 3 Seconds
Start key glows white as machine fills. If door is open then the start key glows
purple
Once full, rinse heating starts. Start key glows orange while heating.
Machine can be started when machine is heating. NOTE: If rinse temperature
is not sufficient cycle countdown will stop at 22 seconds. Washing continues
until rinse reaches temperature required for sanitization and countdown then
resumes.
Start key glows green when machine is fully heated. For different cycles press
the UP and DOWN arrows: Light, Medium, Heavy, Manual or Drain.
Close door/Press start key to start cycle. When manual cycle is selected
machine will continue washing until START button is pressed. Rinsing and
draining follow washing to complete cycle.
Start key glows red during cycle. Pressing Start key again terminates cycle

PRE-RINSING
Food scraps must be removed from dishes by scrapping, dunking in water or preferrably with a Fisher
pre-rinse spray unit. Soak accumulated cutlery in container filled with water before washing.
RACKING PROCEDURES
Do not overload racks or cutlery containers, minimise the overlap of crockery. Wash cutlery unsorted,
handles down (except sharp knives). Cycle times are short and water consumption per cycle low – so
there is no advantage in overloading racks.
CYCLE TIMES
The M2 has a 1, 2, 3 minute cycle and an extended manual cycle.
CHEMICAL
Correct type and quantity of detergent is essential for good results and rinse fluid speeds drying. Use
good quality chemicals and regularly check supply containers. Detergent and rinse fluid concentration
can be changed by adjusting dispensing time on the keypad (refer to page 8 User Programming). Prime
detergent line by turning on the DETERGENT PRIME option in the User Settings menu. Detergent pump
will operate continuously for up to 1 minute and prime the line; repeat process as necessary until line is
fully primed.
DRYING
Single tank commercial dishwashers do not have a drying cycle. However, the machines do rinse at
high temperature which promotes fast drying particularly when drying agents are used. At the end
of the cycle promptly remove the rack from the machine and leave it on the bench for 2 to 3 minutes
before emptying.
Operating Procedures
REGULAR CLEANING – at least once a week
Remove scrap tray (1) and upstand (2). Remove wash (3)
and rinse arms (4) by undoing the central thumbscrews
(5). Inspect all jets – use toothpick or paperclip and
remove arm end-caps if necessary to flush and clear.
Clean and then replace all items.

Issue Resolution
Error 7 Fill failure - check drain upstand is fitted & water supply is turned on and
good flow rate
Error 8 Drain failure - check drain upstand is removed & drain hose is not kinked or
blocked
Not filling Check water supply is on and door is closed
Refills during Wash Check Drain upstand is fitted

Wash too long Check water supply temperature - wash stops at 22 seconds if rinse is still
heating
Foaming Wash Excessive use of rinse fluid and/or low wash temperature can cause
foaming
Poor Results Read and carefully follow the machine installation, operating and care
procedures
All of the following is actually in the instructions on previous pages of
the manual
Pre-scrap and pre-rinse washware
Do not overload dishracks - avoid overlap of plates, wash cutlery
unsorted, handles up
Use quality low foam detergent and rinse fluid - check containers
and adjustment
Use heavy cycle - baked on soil requires pre-scraping and/or pre-soaking
Remove and check wash & rinse arms & jets are clean and rotating freely
If plates are not pre-rinsed wash water may need changing regularly
Check wash and rinse temperatures
Remove rack when cycle ends and leave on the bench a few minutes for
drying

If an error message appears on the control display first try turning the machine OFF for 30
seconds and then back ON. If the error message remains call for service.
