Hi,
I have a Ferroli Modena 80E, and I recently had the Venturi replaced because the gas kept firing on and off every few seconds. At the same time the Engineer also replaced the thermistors, but they were copy parts and not Ferroli.
Now when I have a shower the DHW is getting hotter and hotter, so I have to keep adding more and more cold water to keep the water at an acceptable temperature. At the same time the cold water flow is increasing while the hot water flow is decreasing until the hot water flow becomes so low that the boiler switches off, and the water goes cold.
I've had 2 Engineers look at it so far, and neither could find a fault. They seemed to think it wouldn't be the thermistors, because they'd been replaced.
Has anyone got any suggestions? Thanks.
