I think, from memory, it's a 1050C; from memory only because the model name has been rubbed from the front. Is the model name under the cover too? if it is I'll whip it off, I'll whip it off anyway and get back to you - Paul
Our Gainsboro power shower has started to run cold only, the 'power on' LED is lit at the switch but with the shower pushing water out turning the switch on then off then on doesn't effect the flow at all. The unit has been fine for 5 years. Any ideas greatly appreciated - Paul
