just switched shower - no water now - please help!! All aspects of plumbing questions and answers, help, tips and information

i had an aquatronic 2+ shower which recently became faulty (water was either very hot or very cold).
i attempted to replace this with a second hand aquatronic 1+. as they both had the ame shape backing and interior fittings i just swapped the "inside parts" of the shower over and it seemed to go pretty well.

when i tried to switch it on the power was ok (the indicator light came on) but there was no water coming through. i had turned the stopcock back on to roughly the same pressure, and susequently tried it at a slightly higher pressure but still no sign of water making it through to the shower.

i'm now a bit lost for ideas as to why this is the case.

my previous shower was 8.5kw and my new one is 7.5kw, would this be the problem or could it e the second hand shower i bought was faulty?

any and all help very grateully received,

thanks.

These do have a thermal cut out, I'm not sure what parts you have changed but it would have been better to have bought the same size/rate of shower. If you have fitted the 8.5kw element to the 7.5kw workings it may be that the flow rate is not sufficient enough to get rid of the heat.

Shows the thermal cut off.

hi htg engineer,

it was the entire shower that i swapped over, i just left the outside casing which i left attatched to the wall.

i did read the rest of the instructions from your link and i'm wondering if maybe i just haven't flushed it correctly if that would make a difference. i'll give it a go anyway, thanks for the help.
