Wow. Great restoration. We had a 15790 from new when i was younger did about 16 years solid service with no real probe until the end when the gearbox got noisy.
Then we had a new one think it was a 96702 and that was RUBISH! had a new motor and gearbox within the first 2 years. 3 pumps within first 6 years. new programmer after about 8 years. and it wasn't used any more than the other one in fact probably less. I lived in a house of 6 adults so the machine was on nearly every day.
