ACTION
Clean the scrap screens. Do not forget
the wash pump filter (see pages 13 &
11).
Clean the jets/nozzles. Be careful not
to lose the o-rings (see pages 13 &
11).
The detergent filter in the container
may be clogged. Rinse under water.
Check the detergent tube for deposits.
Clean the line if necessary. Peristaltic
hose(s) will have to be replaced
periodically as regular maintenance
(see page 13). Check for cracks or
leaks.
Pre-rinse the wares thoroughly before
they are placed in the racks.
The unit requires a minimum incoming
water pressure of 1 BAR. Check that
shut-offt valve fully opened. If incoming
pressure is still low, a pressure-booster
pump to increase the water pressure
may be required.
If the water pressure above 3 BAR, a
Pressure Reducing Valve must be
installed (see page 8).
Water level should be just under the
opening of the overflow pipe.
Have the incoming water analysed.
May need a filtering system; or other
product(s).
Straighten or unblock hose.
Call for service. Food or debris in the
drain pump is not a warranty issue.
If the water pressure above 3 BAR, a
Pressure Reducing Valve must be
installed (see page 8).
Turn off the washer and drain the
washtank. Remove as much suds as
possible. Do not replace overflow
pipe. Close the door and turn the
power on. Let unit run for 2 to 4
minutes. Turn off unit, replace
overflow pipe, close the door and
refill unit. Try washing. If the problem
reoccurs, repeat above procedure.
