Check the items below before making a service call. You will be charged for Rheem
attending to any condition or fault that is not related to manufacture or failure of a part
NOT ENOUGH (OR NO) BOILING WATER
Is the electricity switched on?
Inspect the wall power socket to see if it is switched on. Also check the fuse or circuit
breaker at the switchboard to see if it is blown or tripped.
Is the timer in the off period?
If the unit has been in an off period and the water is below the optimum delivery
temperature, the green LED flashes when the unit is woken. To 'wake' the unit press
the hot lever on the boiling water tap or any timer button. The unit will activate the
element and reheat the water to the set temperature.
Is the leak sensor detecting there is water with the unit?
There is a leak sensor in the boiling water unit that detects if there is water in the safe
tray (error code D displayed on the timer screen, see page 11 section F,1). Phone
your nearest Rheem Service Department or Rheem Service Centre to arrange for an
inspection.
Are all Tap LED's Flashing? (safety & orange then green)
The tap lever was pushed down too slowly. Reset the tap button to the OFF position
and fully activate tap lever. If the LED's continue flashing a fault has occurred with
the tap. Phone Rheem Service or a Rheem Service Centre to arrange for an
inspection.
Has there been heavy use?
Heavy boiling water usage can result in the tank level dropping below the low level
probe. In this situation the boiling water pump is deactivated. The green LED on the
tap may also flash due to insufficient temperature as the tank refills. This is normal
operation. Wait for a time period to allow the tank to refill and reheat. The green LED
will stop flashing as the water heats up to the usable temperature.
WATER NOT HOT ENOUGH?
Heavy usage
You may find that due to heavy boiling water usage the boiling water volume required
may be less than what is available. This is due to insufficient recovery time being
allowed. If the available water temperature is too low the Green LED will flash until
usable temperature is reached.
High altitude
The boiling water unit is fitted with automatic altitude calibration to prevent the water
from continually boiling, which is not energy efficient. Different altitudes cause water
to boil at different temperatures. If you believe the water temperature is not hot
enough, recalibrate the unit (see page 11 section 4).
