Thanks for your quick response. Sorry! It’s WF 02867GB/17 but how does the front come off?
So far I have done my metering from underneath and was hoping to withdraw the heater but now realise that it is quite long!
Heater arrived and I was most impressed at the build of the Bosch.
Heater came out OK but I was amazed at the amount of scale surrounding the element (causing localised over heating and the failure) Hopefully when I give it a test run the majority of this will be pumped out.
Would it be a good idea to run a descaler through it or is that likely to cause more problems?
