That the overheat protection for the motors has not been
deployed.
For units with water coil, also check the following:
That the water coil is air free.
That there is enough water flow.
That incoming water is heated enough.
If the fault cannot be rectified, please contact a qualified
service technician.
Residual current circuit breaker (E)
When the installation is protected by means of a residual
current circuit breaker, which trips when the appliance
is connected, this may be due to moisture in the heating
element. When an appliance containing a heater element
has not been used for a long period or stored in a damp
environment, moisture can enter the element.
This should not be seen as a fault, but is simply recti-
fied by connecting the appliance to the main supply via
a socket without a safety cut-out, so that the moisture
can be eliminated from the element. The drying time
can vary from a few hours to a few days. As a preventive
measure, the unit should occasionally be run for a short
time when it is not being used for extended periods of
time.
