Gary September 11, 2014 for Model Number WF219ANW/XAA-0000 The machine displayed OE error code. I removed the dl-s14t pressure switch & checked continuity between terminals. The 2 outer terminals are closed & do not open when I blow through tube on switch (I hear the diaphragm move the switch when I blow on it) The middle terminal is open to both outer terminals & does not change. Based on this test, I ordered new switch #dc97-03716c from you. Is this the correct test & did I order the correct switch?
1 Answer Gary, Yes, with the switch not changing with pressure added then the pressure switch would be the issue with the unit. Read More...
Ronald November 02, 2012 for Model Number samsung wf306law/xaa Looking at part #ap4209074 pressure switch. I suspect it is faulty. I am checking about 20 ohm resistance between the two outside terminals but applying pressure to the line that connects to the diaphram I can hear movement in the switch but there is no switching taking place. No resistance change nor any continuity between the center pole and either of the outside terminals. Question how do you check this switch? I am having erratic operation of the drain pump and the pump is fine. Caught between ordering a complete control board or making sure this switch is the problem. Thanks.
1 Answer Hi. Verify board output voltage on CN 3 : pins # 6 (org) & # 7 (Vio) and Connector CN 3 : # 6 (org) & # 8 (pnk). Voltage output is 2.5 VDC Board output. Resistance : CN 3 : Pin # 8 (pink) & CN7 pin 7 (Violet). 22-24 ohms. The symptoms mentioned allows me to believe the pressure switch part # WP34001324 is bad. Rattling loose internal parts. Otherwise. Thank You. Read More...
