Across switch spade contacts with harness unplugged; electronic output: 40Hz–50Hz frequency signal

Tolerance & Diagnostic CriteriaMechanical switch contacts must transition cleanly on gentle breath pressure. Coil ~22Ω ±5%.

1. Pre-Intervention Electrical Safety Protocols

!Electrical Safety Protocol: Cut 230V mains power before accessing the upper chassis or pressure switch terminals.
!Drain appliance tub completely before disconnecting pressure switch sensing hoses.
!Never blow high-pressure compressed air into electronic analog pressure sensors: internal diaphragms will rupture!

3. Preliminary Mechanical & Visual Checks

Disconnect the silicone pressure tube from the lower air trap and inspect for soap sludge, lint, or water blockage.
Inspect the flexible rubber hose along its entire length for pinholes, cracks, or loose clamp fit.
Thoroughly flush the lower compression chamber (air dome) with hot water to dissolve detergent buildup.

Perform these diagnostic steps before triggering AI Deep Search or replacing boards.Certified Workshop Routine

Frequently Asked Questions: Sangiorgio AL01

FAQ TREE

What does error code AL01 mean on a Sangiorgio appliance?

Sangiorgio error code AL01 indicates: Sangiorgio AL01: Water inlet / filling timeout in Dishwasher; appliance fails to fill to minimum operational level..

What is the root cause of Sangiorgio error code AL01?
