Hi Rizwan, I'm a complete novice myself, so take my advice with a grain of salt. I recently bought a Bii to refurbish myself.
If the temp controller dot is on and the SSR light is on, then it would be trying to heat the brew water. So if that is not working, you have 3 potential problems: 1) The SSR is broken (or intermittently working). 2) The Heating element in the brew boiler is broken (or intermittently working). 3) The steam boiler (which has priority) is staying on and not allowing the brew boiler a chance to heat up properly (pstat not switching power to the brew boiler). You say that when you flush, the brew boiler eventually comes up to temperature; but be aware that the brew boiler water gets preheated in the steam boiler, so if the steam boiler is hot and you run the brew pump, the brew boiler will begin to get heated by stealing heat from the steam boiler. This explains why the temperature goes up when you run the pump. When first testing my machine I had an earth fault in my brew element, so had it completely disconnected; despite this I was getting fairly hot water out of the brew boiler! Best bet would be to hook up a multimeter to the brew boiler heating element directly and watch when 120V is present. If you see 120V there and no heating of water (or inconsistent heating), you can assume there is a problem with the element. If you don't see 120V there when the steam boiler is off (and the brew boiler temp is still low), then you can start to move onto checking the SSR and any other series connections (such as the over temp switch).
