(CVA 2652/2662 Only)
Cause:
Faulty grounding of front fascia.
Remedy:
Note:
The fascia is coated with CleanSteel and is non-conductive. Take
measurements at the outer edge.

appliance casing.
2. Loosen the top door hinge.
3. Pull out the hinge recessed part (this usually comes out automatically
when the door is closed and opened).
4. Move the spring back and forth. The spring should press against the
stainless-steel fascia.
5. Tighten the hinge again.
6.
Check the resistance again between the fascia and appliance casing.
