T, thanks for ur prompt reply..
If its filter on main water inlet problem, the hot water in kichen is supposed to be affected as well, not only shower, is it right?
BTW, what is dhw? am not good at this stuff.

Firstly, check the filter on the mains water inlet to the boiler, is clogs up often enough. Then check the dhw thermister. Then the dhw flow/turbine is working correctly. Failing that replace the plate heat exchanger
