The spare part “Rolling diaphragm for pressure accumulator pump” is intended for subsequent ordering by you if the repair test shows that it is worn out.
The rolling membrane, also known as the pressure bag, serves to spatially separate the air pressure and the heating oil and is located in the pressure accumulator.
Of course, you can change this yourself if you have the right skills.
