Electric shower - water hot and cold (no change in pressure)

[krow]

Hullo all
This happened quite a while back so I'm going by memory here.
Our shower (triton- electric only) was installed for a few months and then suddenly stopped working one day (no out put of water).

Our shower was setup so the electricity supply to the shower is controlled by one of those 'pull' lights (it drops down from the ceiling) and a Start/Stop button on the shower turns it on and off.

The little light for the dropdown light had gone off, and I believe wemust have then replaced the fuse (I will check again on this as someone else sorted it out) after a while (switching to the bath) and then we found - since the shower became usable again, the water temperature varied between extreme hot and luke -warm if placed at the '2-bar' heating setting - (1 bar doesn't heat it beyond luke-warm) irregardless of the temperature setting. The strength of the water comingout does not vary with temperature either and is quite weak.

Any suggestions would be very much appreciated

Thanks!

my guess is that the heater element has furred up and keeps hitting the overheat cutout.

Also worth descaling the head and hose at the same time.
