COMPONENT REPAIR AND REPLACEMENT

8.2.15 Door Safety Switch and Magnet

(All Models)

All dishwasher models utilize a magnetic reed door
safety switch mounted in the left front corner of
the slide out control cabinet.

A door magnet operates the safety switch when
the door is fully closed.

The dishwasher will not operate if the door is open
when the POWER pushbutton is pushed ON to
fill the machine.

If the dishwasher is in an automatic cyle, opening
the door will pause the cycle. When the door is
closed, the cycle will resume where it left off.

To replace door safety switch:

1. Push the POWER pushbutton off, if

machine is ON, to enter auto-shutdown.

2. Turn off main incoming power.

3. Open the door and remove (2) screws,

one in each corner of the top hood.

4. Pull the slide-out control cabinet forward.

5. Pull the mylar drip shield back.

6. Disconnect the switch wires from

T3 and T4 on the Timer Control Bd.

7. Remove (2) 6-32 grip nuts holding the

safety switch.

8. Reassemble in reverse order.

CAUTION:

Do not overtighten the safety switch
retaining nuts. Overtightening
can damage the switch.
