Samsung DMT300RFW issue (Normal + Quick flashing)
« on: December 10, 2014, 01:10:13 PM »

Hello,

We are having an issue with our DMT300RFW. Whenever we try to use it, after a long time the Normal and Quick buttons start flashing which indicates a high temperature heating error.

Any ideas on what I can check or do to fix this?

Thanks in advance!

Suspect: Heater relay. Main PCB. Thermistor.
Technical Description: Water temperature sensed above 176F during operation. Possible defect : Thermistor error, Main PBA or shorted heater relay.
