[Chalked]

Hi all

Turbine pal , done loads , as far as I know they are different

 

[Chalked]

Having never swapped one. Is it an easy swap?

 

[townfanjon]

Yep , but they can often take some shifting .
Just check the sensor on the top , run hot tap it should go solid red. When the turbines are on the way out they seem to give an intermittent red and then non at all .
The sensors seem reliable , I havent ever changed one.

As above really if the sensor is sort of flickering then the turbine is beginning to fail.

Great advice .
1 in stock at the local bum Center, so bagged it for pick up in the morning.

Thanksarty:

Check its the correct one for output of boiler as they are different colour coded restrictor in them.
You will see when you remove but should be supplied with the right one once the supplier knows the boiler model and output/g.c. number.
As above may need a gentle tap on the spanner to encourage it to move initially.
A wet vac is great for taking out as no mess and suck clean any debris in flow turbine holder area in block.
Cheers,
Andy

Thanks for the tips guys.
Absolutely bang on! Light was flickering and was an easy job to replace.

Thanks again.
