8 years old Modena 80E combi boiler.
Been getting intermittent hot water for the last couple of months, so called a boiler engineer.
He replaced 1 scaled thermister and cleaned the filter and tested the hot water taps, it worked but it was always intermittent, so wasn’t sure if it’s cured or not. But after 2 days later the problem started again, as the hot water fails to arrive on first attempt and it does not ignite. Only after several attempts, it starts. Also our mixer shower gets very hot water, when it works.
Not sure if it’s to do with low water pressure in our block of flats for the problem.
