I agree there is an end of life for appliances. On the other hand I have found an excellent appliance repair place nearby. My dishwasher started making noises - it turned out to be the thing that ground up food on the way to the pump. I got a rebuilt pump and a lot of instructions on how to replace for $35. It is still running 2 years later - on a 15 year old dishwasher. It did take 4 hours to pull, remove, replace, and re-install the dishwasher - my first time.

So think about your time and the age of the appliance. A new one may be $200-300 and quieter - then it will last another 15 years.

Good luck! We old diesel folks just have to try and repair something before getting rid of it.
