All the newer machines have the electronics and cheap China-made parts that break down on a regular basis. At least you have a Hobart LXG and not a Canadian Disaster built to break Moyer Diebel POS carousel glasswasher behind the bar. That damn thing does 1/10'th the work the Hobart AM-14 does and shits a brick 10x as often.
As far as old Hobart DW's I have experienced a KDS-15, AM-9-T2, WM-5H, AM-11, AM-12, CM-2, C-44, KDI-20 and KDP-20. For the modern Hobarts I've worked with the C-44A, Am-14, FT-820 KDS-21 and LX-30 All were great. I will take exception on the made for Ecolab/Ecotemp ET-20 and ET-40, While better than an Auto-Chlor or Jackson they did not perform to the usual Hobart washing standards. I have also used older Blakeslee, Champion, Vulcan, and ADS DW's.
