The following picture shows the top-positioned heat exchanger seen from above.
In the centre of the heat exchanger there is the water in-let pipe assembly
through which heated water under pressure passes. Top left >>at 10 O’clock<<
there is the earth connection with a brass seal under which the temperature
sensor (Minimum-Maximum operating temperatures- older installation layout)
can be found.
5.
On the left side >>at 9 O’clock<< there is the reversible thermostat. In the
middle, between the two electrical connections, the reverse push button can be
seen (beige-brown). Test the thermostat by pushing in the button. Wait to see
what happens!
6.
After the reverse push button has been set in the pushed-in position, close the
machine for testing (do not reassemble the top front cover!). Switch the machine
on following operating instructions. Wait until the top left and top right leds
(showing brewing water and hot water/steam temperature) remain alight. For
testing purposes, turn the knob on the front panel and check whether hot water is
delivered from the wand. In the event that the thermostat should be triggered
again, then the fault could be with the sensor on the corresponding heat
exchanger. In this case, disconnect power supply to machine and open it up.
7.
Follow the photo sequence and explanation in the next section to replace sensor.
This procedure is for the >>old<< type of sensors.
