Had my TMX 4 years.
It has had a new motor and new scales, recently... the cost of repair was $380 which I was happy with.
The fault was mine - I dropped it on something not long after I got it and the rim dented. This meant it leaked. I did not realise that was a problem for the machine until it recently stopped. The liquid had been running down the back, under the machine, up the vents and into the motor, as well as up through the holes in the feet to the scales. The repairer fixed the rim, so now there are no leaks and it runs like new!
