Ideal Independent C35, Hot water only when tap fully open

[AndyVR6]

Hello, we moved house recently, the new house has an Ideal C35 combi boiler that is approx. 3 years old.

It works well, except that DHW will not come on unless the hot tap is fully opened. We have good water pressure/volume, and the issue is the same at the kitchen or bathroom tap, so we waste a lot of water just trying to get it to run warm for hand washing etc.

Is it likely to be a faulty sensor, or something incorrectly adjusted?

Thanks.

Hot water flow sensor stuck?

same problem... if you can open the front and check the sensor on top of the flow cartridge (all in here http://idealboilers.com/wp-content/uploads/sites/2/2013/08/Independent+-Installation-Manual.pdf) if its flashing led red and not on solid then the cartridge is more than likely shot a new one will cost about 20 quid... if its no led it could well be the sensor... i just replaced my cartridge and all working great.... if you want feel free to email me and ill go through it [email protected]

Thanks for that, I have the same manual, seeing that it involves disturbing the casing seal I will give it a miss and get a gas fitter in, it's good to know the parts involved though and the costs, thanks.
