Boiler stat knackered (i think) - a few questions

[jawbreakers]

Hi there - i have some questions that i hope can be answered - i believe my boiler stat is knackered-the header tank pumps over when my heating and hot water are on (heating quicker) - this happens after about 25 mins, and then it continues every 5-10 mins. There is a gushing sound shortly after - and the process lasts for about 15-20 seconds. Is this rare?

Is there anyway I can double check using a multimeter/other way/device to make sure 100% that the boiler stat is the fault?

I have a Potterton Flamingo II RS50 wall hung, room sealed balanced flue boiler. Is it still possible to get a boiler stat for this boiler ?

Last point (sorry for the long post) - is it possible to change a boiler stat myself as a home owner (and not a corgi reg engineer) ?

Thanks for listening...

certainly sounds like the stat has gone part should still be readily avialable and it is a diy job as no seals or gas jkoints are broken ,cost around 20 quid

thanks namsag - i will call potterton directly and try and get a part. but before i do, is there any test i can do, using a multimeter perhaps, to make sure 100% this is the faulty part??

I presume the stat just has 2 wires that unscrew from the solenoid?
