Jeros AL 07

What does Jeros AL 07 mean?

AL 07 means the lid contact is malfunctioning — the control is not seeing the contact switch when the lid moves. The manual's remedy is a power cycle, with an engineer call-out if the alarm returns. Note the machine's separate no-start troubleshooting also lists a maladjusted or defective lid contact (S6) as a cause of the machine not starting.

Symptoms

• AL 07 shown on the operating panel display
• Alarm returns after switching the machine OFF and ON again
• Machine may refuse to start with a lid-contact problem (S6 listed in the no-start checklist)

Common causes

• Lid contact not switching when the lid closes
• Lid contact (S6) adjusted incorrectly or defective

Diagnostic steps

1. 01

   Switch the machine OFF and then ON again

   Power-cycle the machine per the manual's first remedy for AL 07.

2. 02

   Check whether AL 07 reoccurs

   If the alarm stays clear after the lid is operated normally, resume service.

3. 03

   If AL 07 reoccurs, call an engineer

   The manual instructs an engineer call-out for a recurring lid-contact malfunction — adjustment of the S6 contact is a service task.

When to call a professional

Call an engineer if AL 07 survives a power cycle — the manual's instruction. The lid contact is a safety-relevant interlock on these washers, and its adjustment (S6) appears in the manual's service-level troubleshooting, not the operator section.
