The spare part "Rolling diaphragm for pressure accumulator pump" is intended for subsequent ordering by you, if it was determined during the repair inspection that this component is worn.
The rolling diaphragm, also known as a pressure bladder, serves to physically separate the air pressure from the heating oil and is located inside the pressure accumulator.
Of course, if you have the appropriate skills, you can also replace it yourself.
