No the problem comes down to poor maintenance. Not the manufacture. The manufacture requires you to do routine maintenance. If you do not keep your water filtered, soft, and replace parts as needed then the machine will break. The warranty last for 1 year for most machines. If a part is faulty it will most likely fail within the 1st year of use.
Other wise simple things like screens and a few gaskets need to be replaced every 6 months. The flow restrictors need to be replaced yearly. About every 3 to 4 years you need to do a complete overhaul.
This includes descaling, replacing all the gaskets, screens, restrictors, overpressure valve and seals, expansion valve components and seals, inner boilers if replaceable. The whole 9 yards. Basically the only thing that doesn't get replaced is the boiler, piping, electronics, and the frame.
