What to do if the VAT 61228-KAGG-0002 display shows «E 20» (fatal error - limit stop of valve unit not detected)?
- MMicheal ClarkSep 23, 2025
If the VAT Control Unit display shows «E 20», it indicates a fatal error where the limit stop of the valve unit is not detected. This could be due to a clamp coupling screw that is not fastened. Tighten the screw, referring to chapter «Maintenance» for details.
