But you'd have to do so with the power to the dishwasher off! Or else you'd possibley get sprayed with water when it came on, while you are jumpering with the door open!īut you should not have to jumper the wires if you know you are getting the 110 in the one wire, but then, make sure we are on the same page regarding ohming out the switch itself. You can bypass the switch by jumpering the two wires (connecting them together). If you got 1 ohm, in this test, it would mean the switch is good. With one test lead on one terminal, and the other test lead on the other terminal.
In ohm testing you have to forget the wires now and concentrate on the switch's terminals with one of the wires temporarily pulled off. (I always prefer to disconnect one wire so as to not get some backfeed, skewing the results) Your analog? meter will go all the way to the right if the switch is good, or stay all the way to the left without moving, if the switch is bad. You shoujld have no resistance in this test, whjen yor meter probes are on each of the connectors on the switch at the same time. Now switch your meter to "ohms" and with the diswhasher breaker in your panel box turned off, ohm's test the switch by manually operating the latch mechanism simulating the closed door position. If you have established that 110 is in one of the wires there, then you have to test the switch itself. If there is no presence of 110, probe the other wire. Then put your other probe to a ground, while your meter is set to the 250 volt range, to see if you have 110. In testing the door switch with a voltmeter, you want to first establish if you have 120 coming into one of the door switch wires.
