Unscrew one electric leading wire to the transposition terminal , and curtail one investigation of the VOM to each terminal . If the time reads zero , the switch is not faulty . The trouble is in all probability in the timekeeper . If the meter study high-pitched than zero , the transposition is faulty .
footmark 3 : Replace the switch with a raw one made to meet the dishwashing machine . The substitution is take to a mounting bracket with screws ; remove the fucking to get the one-time switch out .
Step 4 : associate the new switch the same way the old one was plug in .
Servicing Timer and Control Switches
Because the timekeeper controls many mathematical operation , a faulty timekeeper can make many problems . The timekeeper is a complex component , so you should n’t try a do - it - yourself haunt . Test the timer with a VOM set to the RX1 scale . To make headway admittance to the timekeeper , slay the front control panel . The timekeeper is forthwith behind the main timer control knob . Disconnect one of the timer ’s terminal wires and clip one probe of the VOM to each terminal . If the meter record zero , the timer is working . If the metre reads higher than zero , the timekeeper is faulty and should be interchange .
If possible , use the same procedure to test the chooser and cycle switch . The wiring hookup , however , may be too complicated to image out on either of these switches . If you are n’t sure you may deal with these switches , call a professional service person . supplant a defective timer – or a faulty control shift – with a raw one made for the dishwasher .
