Hi Cecil, I posted recently on on bread not rising as much etc,what I found out is that breadmakers have very little in them to go wrong, I then changed the yeast which made no difference, then I purchased Canadian bread flour which is often added to British/European flour to increase the gluten content and the result was well risen,light bread.I had some Allinson's flour and wrote to them and they and other flour producers have known about this problem for the past 2 years.The wheat harvest has been affected by the weather ,the upshot being that there is less gluten to get the bread to rise.Asda should reimburse you.
