Troubleshooting
Grant have a dedicated service team who are able to resolve any problems that occur
with your Grant digital ultrasonic bath. However, on many occasions it is possible that
the problem can be rectified by the operator.
If any of these problems persist, the Grant Service Department can be contacted on
+44 (0) 1763 260811 or
[email protected] .
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:
“Liquid Level Low”
Fill the Grant digital ultrasonic bath with water so that
it is above the fill line 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:
“Sonics Low”
The Grant digital ultrasonic bath is fitted with an
ultrasonic power detector, which monitors the
ultrasonic activity in the bath during a cleaning cycle.
If the ultrasonic power drops below a certain point, the
cycle will be incomplete 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.
