no dhw on ferroli optima 701

[punkc]

Hi, I have issue with a ferroli 701 optima boiler. The boiler does not fire up when hot water tap switched on.. ie no DHW. However central heating is working fine, and i am able to use hot water when this is running.
I have looked at diagnostic LED'S as stated in manual. I seem to narrowed it down to 3 things
1) faulty Dhw sensor
2) faulty Dhw flowmeter------ or flow switch?
3) Scaled up heat exchanger? ( not from LED's , but off this forum)

not sure where to go next? i am obviously gong to use a Corgi reg professional to do it. I have policy with BG, but they seem hell bent on me buying a new boiler. I admit i am going to have to replace the boiler as aware it is not a great make. However i am having a extension built soon and rather do CH system then. Please could any of professionals out there give me some much appreciated advice. I just don't want to give BG the satisfaction of taking me for a ride. I am going to give my business to good independent plumber.
cheers

sorry forgot to mention that cold water intel valve was leaking, ie staying open, i replaced that as water wa dripping from outlet drain. Could this valve have damaged flow meter?
thanks

Check the inlet filter is not blocked left side of flow meter first then I would suspect the flow meter.

I used BG as I was new to the area and knew no one in the trade, very expensive in my experience since. I am a plumber now but not corgi as I don't have the necessary experience to qualify yet.

All I can say is you'll get plenty of good advice from the lads/ladies? on here that are.

Why have you just ignored what gas4you has said....

Hi guys, not ignored what gas4u said, just finding it hard to find filter, can only see flowmeter, which is connected to cold water inlet. I don't doubt the advice given on here, i am not a professional like the lad/ladies on here, so just trying to gather as much input as possible. ie there is no substitute for experience.
thanks

Does LED2 light when you turn on a hot tap ?
Is LED4 lit at that time ?
