This Whirlpool washing machine does not flash out codes, but displays them on the 5 progress lights from left to right. I came across a machine which after 2 minutes of running on a wash program came up with 1,3,4&5 light lit from LtoR along with the service light. I proceeded to test the insulation – perfect 199M+, motor arm taco field, heater, NTC, Valves, and pump resistance – All fine. I then ran the machine and it worked perfectly and has done ever since. Does anyone have an explanation, apart from healing hands!
