Tower 10 cup Coffee Maker T13001 - I bought this coffee maker from the Range in June 2019. On first use it made a very high-pitched whining noise which could be ignored as it is used in the utility room and we can shut the door. It was so high-pitched my husband could not hear it. It made coffee efficiently and easily but stopped working today 20/10/2019. There was no problem with the shop replacing it but on switching on the replacement, again there is a very high-pitched whine. I will continue to use it but am anticipating another short period of use before having to invoke the warranty. Disappointing.
