Troubleshooting
Ultrawave have a dedicated Service team who are able to resolve any problems that occur
with your
Hygea 6427
. However, on many occasions, it is possible that the problem can
be rectified by the operator.
The unit fails to turn
on (no display is
shown)
Check that the unit is plugged in and that mains electricity is
present.
The screen displays:
“FLUID LEVEL LOW
OR NO DETERGENT”
Fill the
Hygea 6427
with water so that it is between the MIN and
MAX level indicated inside the tank.
If you are using “pure” water (eg. De-I or RO) ensure that the
detergent has been added.
The screen displays:
“LID OPEN
Please Close Lid””
Close the lid.
If the lid is already closed, there may be a problem with the lid
sensor. Attempt to run another cycle to see if the problem reoccurs.
The screen displays:
“SONICS LOW”
The
Hygea 6427
is fitted with an ultrasonic power feedback circuit,
which monitors the ultrasonic activity in the bath during a cleaning
cycle.
If the ultrasonic power drops below a certain level, the cycle will
abort and this message will display. This is not necessarily caused
by a problem with the machine.
If this message displays, run another cycle to see if the problem
persists.
The screen displays:
“OVER TEMP”
Drain and refill with fresh cold water
The
Hygea 6427
is fitted with a temperature sensor that
automatically sets off an audible alarm if the liquid gets too hot.
Ultrasonic activity itself will heat up the liquid at a rate of
approximately 10-15°C per hour. If the
Hygea 6427
is operated
continuously, it may eventually set off the audible alarm because
the liquid is too hot.
The screen displays:
“UNDER TEMP”
The cleaning solution is not yet at the minimum temperature. Wait
until the cleaning solution has reached the minimum operating
temperature.
The screen displays:
“NO MC CARD
PRESENT”
If the Validation Mode selected is to write to the MC Card, then the
Hygea 6427
will detect if the card is present.
If the MC Card is not present, and “MC Card Only” is selected as the
Validation Mode, then the cycle will not begin.
If “Printer & MC Card” is selected, then the cycle will run, but data
will only be stored on the printed validation ticket.
Refer to the Administrator Instruction Manual for information on
adjusting the Validation Mode.
If any of these problems persist, the Ultrawave Service Department can be contacted on
+44 (0) 845 330 4238 or [email protected].
There are no user serviceable parts inside the Hygea 6427.
