Richard I have fitted all parts from repair kit and still the htg comes on when ht/wtr runs and the ht/wtr is hot then cold this is caused because the boiler is running up to temp and shutting down on the stat I am about to remove the plate h/ex and wash it out will let u know the result.

replacing the diaphragms alone may not help. there is a service kit for these boilers which contain spindles and bobbins which operate in the divertor valve. what is the problem with it?
