I cleaned my hot water tank, as I do on a regular basis, last night but as I installed a new filter after flushing everything through this morning the machine was showing a yellow warning saying no filter in machine. Hence I could do nothing everything stopped. Customer services were wonderful and I got a call back from a woman named April. She was absolutely wonderful .... we honestly laughed so much throughout her instructions. What she taught me to do with a tea towel. cooking tongs and a skewer was amazing. Reminded me at first of an awful experience with a pair of tongs when I was a hotelier in Blackpool .... I had to improvise !!! Problem solved and everything working wonderfully as always now. Pre her call I had just clambered to the back of a cupboard to dig out a kettle. Thank goodness I have not had to use it. Many thanks to a wonderful company
