Sequential Factory Diagnostic Tree

Perform each diagnostic step in order. Disconnect electrical power and turn off utility shutoffs before inspecting wiring or internal mechanical assemblies.

Step 1: Physical & Electrical InspectionMultimeter & Visual

Action: Turn off circuit breaker for 5 minutes, inspect touch console, and press each button firmly to release mechanical binding.

Bench Test: Check if any button feels sticky, depressed, or gummy from laundry detergent residue.

Expected Standard: All buttons travel freely with crisp mechanical/tactile rebound.

If Failed / Out of Spec:

Clean bezel around buttons with electrical wipe to remove residue.

If Passed:

Proceed to Step 2.

Step 2: Physical & Electrical InspectionMultimeter & Visual

Action: Disconnect electrical power, remove console panel, and disconnect the touch ribbon cable from electronic control board.

Bench Test: Measure resistance across keypad ribbon cable matrix pins with no keys depressed.

Expected Standard: Infinity (open circuit) across all matrix pin combinations.

If Failed / Out of Spec:

Shorted membrane trace detected. Replace touch keypad console membrane (134557300).

If Passed:

Proceed to Step 3.

Step 3: Physical & Electrical InspectionMultimeter & Visual

Action: Inspect ribbon cable connector receptacle on electronic control board.

Bench Test: Inspect receptacle pins for bent contacts, oxidation, or debris.

Expected Standard: Clean gold/tin pins; clamping latch locks ribbon securely.

If Failed / Out of Spec:

Clean socket or replace connector latch.

If Passed:

Proceed to Step 4.

Step 4: Physical & Electrical InspectionMultimeter & Visual

Action: Reconnect power with keypad ribbon disconnected.

Bench Test: Observe if E68 error recurs with keypad completely disconnected from board.

Expected Standard: Error clears when keypad is removed (confirming keypad failure).

If Failed / Out of Spec:

If error persists with keypad disconnected, the internal microprocessor key-sensing circuit is damaged. Replace main electronic control board (137008000).

If Passed:

Replace touch keypad membrane (134557300).
