Fig. 9.6 Primary heat exchanger holder

•  Disconnect the plug-in connection (

2

) of the thermal 

fuse in the primary heat exchanger.

•  Remove the three screws (

3

) on the primary heat 

exchanger holder.

•  Turn the holder to the side around the rivet (

1

), pull 

the primary heat exchanger downwards to the right 
and remove it from the appliance.

•  Mount the new primary heat exchanger in reverse 

order and replace the seals.

  Caution!

Risk of damaging the primary heat exchanger!
Neither loosen nor retighten the four screws 
(Fig. 9.5, Pos. 4).

  Caution!

Insert the seal rings for the flow and return 
pipe on the primary heat exchanger with a suit-
able lubricant (e.g. soap lye).
Make sure the clamps are sitting correctly on 
the flow and return pipe (see Fig. 9.5).

•  Fill and evacuate the appliance and if needed, the 

plant after installing the new primary heat exchanger.

•  After completing the work, check for gas and water 

leaks and perform a function check (see Section 7.6)!

9.6 

Replacing electronics and display

  Danger!

Before replacing the component, comply with 
the safety instructions in Section 9.1.

•  Comply with the assembly and installation manuals 

provided with the spare parts.

Replacing display or electronics

If you are replacing only one of the two components, the 
parameter adjustment functions automatically. On turn-
ing on the appliance, the new component takes over the 
previously set parameters from the components that are 
not replaced.

Replacing display and electronics

When replacing both components (spare part failure), 
after being turned on, the appliance goes to fault and 
displays the error message “

F42

”. 

•  In the second diagnosis level, under the diagnosis 

point “

d.93

” enter the number of appliance variant 

according to Table 9.1 (see Section 8.1.2).

The electronics is now set to the appliance type and the 
parameters of all adjustable diagnosis points correspond 
to the factory settings.
