For $200 a repair man told me to throw my three-year-old dishwasher away and buy another thousand-dollar dishwasher brand new plus pay for install. They told me it would be cheaper for me to buy a brand-new dishwasher than for them to replace the two controls.
Thanks to the very step-by-step videos and for $250 & two hours of my time I was able to replace both controls and I now have a perfectly functioning dishwasher!
