Worcester Combi Boiler (OIL) Hot Watter issue

[Starship1]

Can anyone please offer some advise. I have a Worcester Combi Boiler oil heatslave 15/19.At the moment my hot water is almost non existent, just trickling out, fair pressure from the cold. I have had this issue in the past, after which I had a new heat exchanger fitted, solved the issue, later because I had to have another fitted with in the year and told my water was very hard, after the second fitting of a heat exchanger I fitted a combi mate, worked well and later fitted a water softener. Haven't had any issues for about 3 years, but now all of a sudden it seems the problem has returned. Before I go out shopping, can anyone tell me if it could be something else causing the problem, or is it most likely to be another heat exchanger change. Thank you in advance...

Sounds like the heat exchanger but could be the heating side of it. Have you ever had your system power flushed or a magnetic filter fitted. Before you go buying a heat exchanger get a qualified often technician to diagnose. Will be cheaper than throwing parts at it.

Not familiar with your boiler, however if the flow rate through the hot taps has reduced then it does indicate a restriction somewhere. If your cold supply isn't affected then I'd be honing in on the boiler. It could be a filter blockage, if it has one or, as before, scale build up. Is your water softner still effective? My be worth checking?

Thanks guys. Softener working ok. The filter I suspect is the one at the mains inlet of heat exchanger. Boiler now stopped firing up. All cold water is supplied to taps via mains.

Update. No filter found. after watching some youtube clips it might be possibly be the capacitor, however I don't know where it is. Unless anyone has any other ideas. Trying to get a plumber out is near impossible.

It is not the capacitor.

try looking for an oil boiler technician rather than a plumber

Boiler man came out today on his way home, a switch under the control area reset the system. As the heating side had not been used for so long, a unit had seized up. a quick fix and all is running now. However as he was in a hurry and had not got the time today he was only able to do the fix., at least we have heating and hot water now. I am a little concerned on the hot water running into the sinks and bath, it does not seem to have that much pressure, running very slowly. I have given this some thought and my next question is, I have mains running through a combi mate and then through the water softener, could this restrict the flow ?, would it be better to by pass the combi mate.
