I recently ran a "Quick wash" for the first time in over 15 years. The machine will not shut off. I have pressed the last button to stop the machine and also tripped the circuit breaker to stop the machine for grinding, no water involved. But when I reset the circuit breaker, the cycle continues to grind. How can I reset this? Machine about 18 years old w no previous problems. Always run full wash except this time. Regards
