| Damaged blast chiller power card | Replace power card | |||
| EA3 | Overpressure | The blast chiller stops and it's impossible to restart (remains the letters EA3) | Overpressure in the refrigeration circuit | Switch off the power supply of the blast chiller, wait for some minutes and then switch on again. If remains the letter EA3 check the refrigeration circuit |
| Damaged blast chiller power card | Replace power card | |||
| EA4 | Filter cleaning | Don't change the normal work of blast chiller but it will always remain the message EA4 for 3” | Filters working limit reached | Clean or replace the filter |
