12. If it was clear at the start of the repair that the sensor in the bottom heat exchanger
(responsible for Espresso coffee temperature) may also have a problem, then at this step
of the repair, the bottom sensor (old installation layout) should be replaced in any case.
This means that the top heat exchanger has to be completely disassembled, following the
procedure in the next section.

a.

Disassemble the central water in-let pipe. Next, remove the flexible tube from the
elbow union (press ring on the union in the
direction of union and slide out tube in
opposite direction).

b.

Work carefully when disassembling and reassembling the elbow union.

The thread on the elbow union is very delicate and can easily be ruined by over-

tightening. When reassembling, apply >>Loctite<< sealant to thread and tighten

>>gently<<.

Press ring in direction of elbow union

and slide out tube

First loosen top hex

nut using a >>SW 10<<

spanner turning

anti-clockwise.

Then loosen >> M8<<

nut and remover top

and under plates
