I have a Mira Sport Max 10.8 kW. It has 10mm cable, a 50 amp fuse and has been working fine for 2 years.
This morning I turned it on and all was fine for 5 mins and then it stopped. Went downstairs and the shower fuse and the 63 A RCD fuse had tripped.
Tried again and same thing.
Turned temperature down to cold and same thing.
Tried it on Low & Medium setting and all is fine.
As soon as I press the High button the RCD trips.
Can anyone offer any suggestions?
Out of interest would having a ridiculous amount of limescale effect things?
We have to clean the shower head every 2 weeks because we get so much of the stuff, I'd hate to think what the inside of the shower was like or are they engineered not to accumulate limescale?
