Fairly new breadmaker user though I?ve had it for a while. Have a Morphy Richards and made a lovely loaf the day before yesterday. This morning ? so disappointing - I awoke to a loaf that had sunk. When I got it out the bottom half appears to be cooked but the top half crumbles like chalk in my hands. The only difference in ingredients is that the first time I used 3 cups of white flour and 1 cup of spelt flour and this time all white flour. The kneader blade was properly put in and I think the base was properly put in ? didn?t notice that it was v easy to take it out. From looking on the internet it seems that you have to use warmish water which I didn?t do ? I took it from the filter but did that too first time though maybe the water had been in the filter longer so warmer?? Can anyone help? I was going to make another loaf but haven?t got any more flour TIA
