hi there,
i have a vokera linea 24(sealed) and it heats radiators fine but not hot water. My water pressure is not great but it never has been and it was previously ok. Could this be caused by a blockage or is it more lilkly to be a part problem. Any advice would be a big help.

There is a domestic hot water diaphragm that wears quite easily on these. On the left hand side, the diaphragm pushes a fulcrum arm, which in turn moves the diverter valve and makes a microswitch.

Two options;

A) Replace diaphragm (most desirable, 30 mins work)
B) Adjust End of fulcrum arm (If i remember rightly two screws onto switch/diverter valve)
This boiler does not have a domestic diaphragm or the aforementioned beam. It does not share any parts with the boiler that has domestic manifold and diverter linked with this beam.

Check the cold supply for adequate pressure. Check the flow rate at the hot tap is 9.5 l per minute. If all this is correct, email me (profile)
