it is >>water tight. Connecting clamp.
When all connections have been made, you can remount
the front machine panel and replace the knob so that
you can better observe how the machine>>handles<< .
Next,
>>only to be carried out by service engineer<<
switch off the safety switch and jam fast.
Now the whole
machine is electrified!!!!!!!
Switch the machine on and let it warm up (temporarily position and fill water
container).
Caution:
in this situation there is an electric shock hazard, and particular caution
should be used when working. Do not touch any electricity-conducting components
inside the machine. Also various components heat up significantly and therefore should
not be touched to prevent burn hazards.
Keep all unnecessary persons away from machine!!!!!!!!
When both the water and coffee temperature leds stop flashing (leds to right and left),
test the machine following operating instructions.
It is important to allow the new pump to draw in mains water supply. First place a
bucket under the water tap and open tap by pushing lever in an anti-clockwise direction.
The pump should run and water from the water container should start to flow through
the system, the valves and the heat exchanger. As soon as the system has been filled and
water is following out of the water nozzle, the pump should be generating normal (not
rattling) noise.
In the case that water supply is not sufficient or the pump continues to make a loud,
rattling noise, and another cause for this cannot be identified, then you should contact
customer service and send a report to the customer service center for advice on how to
resolve the problem.
After testing, if the pump is working without any problems, you can now complete re-
assembly of the machine.
This is the procedure:
a.
Disconnect electricity supply to machine! Release the safety switch at the back of
the machine on the left-hand side.
b.
Check everything one more time and remove the water container once again.
