Anyone know how to get this into test mode? I have a Dishwasher Service Handbook that I downloaded from here - it shows Power + Upper Only + Delay buttons. That does change the display to a #1 and each press of delay start changes the display to 2 - 3 - 4 - 5 etc but no actual tests take place.

Is there another sequence of buttons to use on this model to get into the actual test mode?

Thanks.

I'm not familiar with LG dishwashers, you may want to message jeff1 and refer him to your thread here, he may know. He has a appliance shop in Hamilton Ontario, Canada.

I too have an LG LDF7920ST, and I'm trying to find a Service Manual / figure out how the test modes.

The heat has stopped but everything looks to be ok, so I don't know what to repair / replace... heater, thermistor, diverter motor, whatever.

Can anyone help?
