How can I fix Dolphin 1000 electrical shower?

Hi Doris
I had the same problem could not use the Dolphin shower for 2 years. I happened to buy a cheap bath tap shower sprayer yesterday then tried the new shower rose ( think most shower roses can be easily screwed on the Dolphin) and got continuous warm water. The reason is if the old rose is silted up not enough water passes to carry away the heat from the heater and the thermostat cuts out. Like you the temperature control is jammed now but it is not such a problem. As you can try to adjust the water flow - in the centre of my original Dolphin rose there is a screw that can be loosened that widens the holes somewhat. You can also try descaling the rose in its loosened state.
