I have an Essentials 10.8 shower bought from b&q & installed in my bathroom less than 2 years ago. Has been great, until today water was colder than normal, even though i hadnt changed setting on dial. even as i increased temp control, water didnt get much warmer. Its not running cold, just lukewarm, certainly not warm enough. Fuse is fine, as i know when it sometimes shorts water can run cold. Any ideas? Also, who makes Essentials? I suspect Mira?
i know you're not a thicko, but.....
has the power setting been turned down? ( cold/1/2/3 )
and do you live in a hard water area that may have limescaled / furred up the element?
