I have a Worcester 24 CDi boiler combi
The hot water is a problem, for example, if I run a bath, and put the hot
tap on full, it used to restrict the flow depending on the temperature set
on the front panel of the boiler.
But ohh no it doesn't, it used to, but now I get a mega blast and a bath
full of warm water. The knob on the front does not change the flow
I have been onto bosch about it and they recommend replacing "Domestic Hot
water thermister part number 8716142302"
Now I am not an expert, but this I believe is the component strapped to the
hot water exit pipe, it has some heat transfer compound and two yellow wires
connected to it. I have taken it off and had a look, and reconnected it.
Now assuming I have the correct component, what are the odds of it
failing????, can I measure the resistance across is as the hot water flows
and heats up the sensor/pipe.
Any advice would be most grateful
