Flipper’s discount diswasher fails again

The dishwasher fails again. I call the same repair technician who has already serviced the unit 3 times, replacing the main control circuit board. The technician lets me know that the warranty period is now past, and replacing the control board a 4th time will cost me over $300. At the end of the call he shows some sympathy, saying that my diswasher is the cheapest, most unreliable model on the market, and is typically bought by home flippers. Replacing the dishwasher with a reliable unit will cost between $600-900.
