1st Was a triton Ivory 2, now fitted a gainsborough. not sure of power rating on amps but was working fine before

Trition Ivory 2 is 9.5kw / Gainsborough is 8.5 kw both running from cold supply running to bath taps.

Just opened shower switch up and reads 50amp / 250v, this info any use to you?, thanks for the fast response.

sounds like pressure just dipping enough to cause problems

the cold supply water is comming from a 'self cutting' 15 mm tap which I have seen to be a problem with drops in pressure on outside taps before, could this be same if the water pressure has dropped a little overall and gone below limit ? would you suggest I change the self cutter for a better 15mm tap ?

There is no variation in temp when just left running, it is either hot or cold depending on the temp dial, no variation at all.

if your sure the electrics are ok then it has to be down to pressure,these self cutters can play up,how are the power lights on the front when you use the shower? do they go out when you experience problems?

 

[jase_one]

Lights appear fine and shower appears fine, there is no variation in temp if left alone, if the dial is turned up it Red hot, if turned down it goes totally cold, the temps don't change on there ownwithout the dial being moved, but it only works at both extremes of temp.

I've had a volt meter running across the inlet power and appears to be constant at all times when hot or cold.

not sure what you mean there fella,it sounds ok

 

[jase_one]

I mean the shower is either scolding hot or freezing cold and cannot be set in between to be use, changing the dial does not vary the temp but moves it from one extreme to the other, there is no 'middle' setting that would be useable.

id go for the water pressure although most showers wont allow the heating to be swtched on if pressure is too low,it might just be enough to give you these problems
