Service manual April 2017 Uber boiler
1.1.3 Cleaning:
The exterior of these machines may be cleaned with a damp cloth and a light detergent. Do
not use abrasive cloths or creams, as this will spoil the finish of the machine. Do not use a
water jet or spray.
NB: To avoid the possibility of accidentally operating the Font Dial or buttons when cleaning
the front of the machine, switch the unit off using the switch at the bottom of the unit.
1.1.4 Limescale:
In common with all water boiler manufacturers, service calls resulting from limescale are not
covered by warranty. Fitting a scale reducer or in-line filter is recommended, especially in
hard water areas. This can reduce the build-up of scale but may not stop it altogether. The
frequency that descaling is required depends on the local water supply; hard water areas
need more attention. Descaling of the machine should ideally be carried out by qualified
service personnel.
Descaling Instructions
Descale agents/solution should be added to the Tank via the large tube as shown in photo
below. Follow the descale agent instuctions.
➢ Bring the Uber Boiler up to temperature and allow to fill and heat until Prime Ready
Full is shown on the screen.
➢ Turn off the water supply to the Uber Boiler.
➢ Mix a concentrated descale solution for a 6 litre tank, according to the instructions on
the descaler container.
➢ Press the Boost button and dispense water equal to the volume of the concentrated
descale solution.
➢ Add the concentrated descale solution via the descale hose on the front of the tank
and continue to follow usage instructions on the descaler container.
➢ Allow the descale solution to recirculate in Boost mode two or three times during the
recommended descale time, normally 30 minutes.
➢ Drain the descale solution from the tank using the drain hose.
➢ Turn the water on and thoroughly flush the tank, taking care to use Boost mode to
flush the pump and font plumbing, also.
➢ Operate Uber Boiler as normal.
