hi can you help? i have a vaillant turbo-max vuw 242e, i had someone look at the boiler when it was leaking water,1st he said an o-ring, so he replaced the o ring, it still leaked, another visit he then said the water was comming from the microswitch. is this possible & how easy is it to fix? he told me it wouldnt be worth repairing?
thank you
