Had my Bibo for nearly four years. De-scaled it three times and each time there followed a leak which meant Bibo fitter appointments plus parts. This year was advised that I needed a new hot tank to be fitted - costing £128. Only myself using the Bibo, so is hardly overworked and I don't use the hot water for cooking. Annual cost of filters and UV lamp is £77.50 + 2 Descalers £66 (was told it should have been descaled twice a year though says annually on website). Makes this machine non-economical to run. Total cost for machine/sundries/repairs over less than 4 years = £800. £213 p,a, I have now abandoned it due to the further cost of repair. Who knows if another leak will occur on the next de-scale or whatever. However, on the plus side I will miss the cold filter water and instant hot drinks.
