3.7 Machine Runs Automatically and Chirps When the Door is Opened
Cause:
Faulty grounding of the fascia panel. The ground spring in the upper door hinge does
not have contact with the stainless-steel panel.
Remedy:
Note:
The fascia panel is coated with Cleansteel and is thus nonconductive, so
measure resistance on the edge of the panel.
1. Use an ohmmeter to measure the resistance between the housing edges and
ground.
2. Release the top hinge on the door.
3. Move the spring back and forth. The spring should press against the stainless-steel
fascia.
4. Secure the hinge.
5. Check the resistance again.
