Hi,I have a Mira sport that only has cold water coming from the unit.The power light is on.The low flow light is not lit.There is plenty of cold water coming out.I don't know how old the unit.Please can anybody help.Ray
Already Tried: turning the unit on moving the hot cold selection knob on the front selecting low medium and high setting on the front. turning the unit on / off at the mains.
Hi my name is XXXXX XXXXX lets see if we can get you sorted in the shortest possible time. Do you get any heat if you select the lower temperature and leave to run for a bit?
Hi Andrew, I have just tried that and the water comes out cold.
Are you able to take the cover off and use a multimeter?
Hi Andrew, I am able to do that but I don't have any tools with me tonight.
No problem, come back to me when you have the kit and we can go through it together. Don't answer until you are ready.
Hi, I have a meter and have now taken the front panel of the shower unit.Thanks Ray
The water heater unit is on the right. Can you check the electrical connection on the top of the heater and see if there is any power there.
Hi,It reads 132v ac
It sounds like the power switch is not allowing enough voltage through. Can you check the voltage into the unit - it should be 240V Live to neutral and live to earth.
checked it across the choccy block 240v
Ok, it is pointing to the main switch not allowing the full voltage through, if you have 240V in - you have 240V to the element. Can you check at the element again Live to Earth and Live to Neutral with the meter.
hello just checked again and it has 240 to the poles on top of the element
Do you have 2 sets of connections - low power and full power? If not then you need a new element.
I have 3 settings low medium and high
How many sets of electrical connections on the heating element?
there are 4 poles on the element
There will be a live and a neutral for each element
okay so in that case it looks like I have 2 elements is it likely that both of them have blown?
Yes - one will be for low, the other for medium, then both are on for high.
so is there a way to check that they are definitely not working, ie continuity check.
A continuity test would tell you whether the elements are working. You should check the power to each element
Thanks
No problem
