Gainsborough Energy 3000X Electronic - reduce temp light

Hi, My shower recently cut out, displaying the 'Reduce Temp' light. The water had been on the hot side, so I assumed that the thermal cutout had activated. I left everything in the same state and let the shower cool off. After a couple of minutes, the valve opened again, so I pressed the stop button and it shut down normally. I then tried running the shower on the medium setting and it seemed to be fine for a couple of minutes. It then shut down again when the outlet temperature was only moderately warm. After this, I let it cool off again and retried it, with the same results. As I had replaced the heat exchanger some years ago, I felt confident to open it up and check for a fault. As I suspected the thermal cutout, I started to remove this and, as soon as I put slight pressure onto one of the screws the body of the cutout broke. I removed it and ordered a new part, which arrived today. I've just fitted the cutout and I find that the shower is displaying exactly the same symptom as it did when the fault first occurred. Please can you advise me on what else might cause this fault. I work in Electronics and I'm just about to have a close look at the PCB for dry joints. If you have any information that might help to pin-point the fault, I would be very thankful for your help. Thanks. Best regards, Rennie Hill

Turn the shower temperature control from fully cold to fully hot. When you do this slowly there should be a gradual change in temperature and flow. At fully hot you should have not much more than a dribble coming from the hose, and on fully cold you should have a good strong flow. If you do not have this difference, or the flow or temperature is erratic, then you may have a faulty flow/stabilizer valve.
