Installation Troubleshooting
Machine not starting or filling
•
Ensure water supply to machine is turned on.
•
Ensure power supply to machine is turned on.
•
Check that the water inlet hose isn’t twisted or kinked.
Poor wash results
•
Check that there are adequate pre-rinse processes in place.
•
Ensure high quality non-foaming commercial dishwasher detergent has been connected at the correct dosage
for your site, water quality and application. If uncertain, consult a chemical specialist.
•
Ensure that the wash temperature is between 60°C and 65°C.
Chemical residue on items after the cycle
•
Check water pressure, this is likely too low and below the minimum 200kPa required.
•
Check that nothing is obstructing the wash & rinse arms.
•
Check the rinse fluid dosage is not too high. If uncertain, please consult a chemical specialist.
Dishwasher is foaming
•
Ensure high quality non-foaming commercial dishwasher detergent has been connected at the correct dosage
for your site and application. If uncertain, please consult a chemical specialist.
•
Allow wash water to heat to at least 60°C prior to starting the first cycle as some commercial dishwasher
chemical will foam at low temperatures.
•
Low water pressure can result in above average detergent concentrations. As low water pressure also impacts
rinse results, we recommended this is solved by installing a rinse pump rather than compensating by reducing
chemical dosages.
Other equipment in the kitchen has needed filters or has scale
•
Due to the high temperatures in dishwashers, scale will build up in the wash tank, on the arms and in the rinse
tank. The incoming water should be treated. If uncertain, please consult a water specialist.
•
As with the Combi-Oven, high chloride levels will do irreversible damage to a number of the components inside
a commercial dishwasher. The incoming water should be appropriately treated. If uncertain, please consult a
water specialist.
Pawl drive not operating
•
Clear the area around the limit switch on the roller table.
•
Adjust the clutch tension of the Pawl Drive motor, the Pawl drive clutch tension can be tightened by turning the
2 nuts at the bottom of the pawl drive shaft clockwise or loosened by turning the 2 nuts anticlockwise. (Note:
the tension must be at a level where a person can grab the pawl drive with both hands and stop the pawl drive
motion).
Too much steam escaping the machine
•
Ensure all curtains are in place and positioned correctly.
•
By default the wash thermostat is set to 65°C, reduce temperature to 60°C if required.
•
Check the hot/cold water solenoids connections are connected to the correct water mains outlet.
•
Check vents on top of the machine are clear of any obstructions - DO NOT USE THE TOP OF THE MACHINE FOR
STORAGE.
•
Check that nothing has changed in relation to allowing adequate airflow through the washroom.
•
Ensure that the condenser inlet baffles are fully open.
•
If a dryer is fitted, ensure that this is not creating a backflow through the machine.
Grinding noise from the machine
•
Phase rotation from the main power supply must be checked after installation to ensure correct direction.
(excessive noise and damage to the wash pump can occur due to incorrect direction). Indicator on drive.
Machine stops and refills during the commissioning stage
•
Fit the curtains according to the Operator Care – curtain diagram (page 14).
•
Ensure the Scrap Trays are fitted in the Wash and Rinse Zones.
