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,

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.
