ITW Food Equipment Group 19

What does ITW Food Equipment Group 19 mean?

The machine has detected a chemical deficiency in the detergent, rinse aid or sanitizer supply. This usually means a chemical container is low or empty, the bottle level sensor float has dropped below working condition, or, where no bottle level sensor is fitted, the required jumpers are missing from the chemical level sensor connectors.

Symptoms

• Error code 19 shown on the display
• Poor wash, rinse or sanitizing results
• Detergent, rinse aid or sanitizer bottle low or empty
• Chemical level warning during cycles

Common causes

• Low or no chemicals in the supply container
• Bottle level sensor float below working condition
• Missing jumpers on the chemical level sensor connectors (no bottle level sensor present)
• Faulty chemical level sensor or connection

Diagnostic steps

1. 01

   Check chemical levels

   Confirm there is detergent, rinse aid and sanitizer in the supply containers and refill any that are low or empty.

2. 02

   Check the bottle level sensor

   Verify the float on the bottle level sensor is above its working condition and not stuck.

3. 03

   Check for missing jumpers

   If no bottle level sensor is present, confirm the jumpers are installed on the chemical level sensor connectors.

4. 04

   Restart and confirm

   Restart the machine and verify code 19 clears once chemical supply is restored.

When to call a professional

If code 19 persists after refilling chemicals and confirming the bottle level sensor and connector jumpers, contact your chemical supplier or Hobart Service at 1-888-4HOBART. A sensor or connector wiring fault can keep the machine reporting a deficiency even when chemicals are present, and an authorized technician should verify the chemical level sensing circuit so sanitizing is reliable.
