Cannot Adjust to suitable temperature

[gl]

I have a Gainsborough 8.5 shower. When trying to adjust the temperature it will come very hot or, if turned towards cold it will come too cold. I am not able to ajust it to a comfortable temperature.

Faulty shower.

I take it you're adjusting the (usually bottom) temperature control, not the top power control? The one you need to adjust is the variable one.

Thanks , Steve for the reply.
There is only one dial to adjust the temperature

Thanks GaryMo,
You say it's faulty , is a repair not possible ?

 

[GaryMo]

I suppose it depends what the faulty part is and how economical the repair would be.
When you turn the dial it just alters the flow rate of water through the heater, slower the flow - warmer the water, faster the flow cooler the water.
The heater should give a constant heat.
If you set the dial to a desired temperature, does the temperature fluctuate? Does the water flow fluctuate?

Hi Thanks garymo,

If I turn the control fully to the hot ,the water flow does slow down and the waterb is red hot. When I turn to cold, the water flow is faster and the water goes cold. My problem is I cannot get a comfortable temperature, Its' either too hot or two cold. Should I adjust the water input, ie reduce or increase the pressure.

Have you checked that your cold mains stop cock is fully opened?

Have you had any work done needing the cold mains t be turned off recently?

If not could be scaled up heating element if you live in a hard water area.

Hi Thanks for your reply.

I opened the mains stop cock fully open, and that has done the trick, I can now adjust to a comfortable temperature.

Thanks for all your help
