2. Compact Home Symptoms of the problem (click on the relevant line) No display on the unit The machine has frozen up The oxygen consumption is too high. The machine switches on but nothing happens even if you override manually. The right hand pressure gauge is below 2.5 bars. The right hand pressure gauge is above 2.5 bars The pressure on the right hand pressure gauge does not reach 2.5 bars The pressure on the left hand pressure gauge remains at 0. The pressure on the left hand pressure gauge is above 2 bars. The Norton tube (noodle) on the equipment outlet disconnects constantly. The equipment will not run in automatic mode. The equipment does not work and the machine is displaying an error code.

3. Yes No Home Is the equipment connected to a power supply?

4. YesNo Home Disconnect and reconnect the equipment to reinitialise it. Has the machine restarted?

5. YesNo Home Is the equipment connected to the regulator properly? And is the pressure at 6 bars? (sometimes the connection is poor due to oxygenation)

6. YesNo Home Is the pressure on the right hand pressure gauge at 2.5 bars?

7. YesNo Home Is the equipment connected to the regulator properly? And is the pressure at 6 bars? (sometimes the connection is poor due to oxygenation)

8. Manually override in small increments by turning the regulator clockwise to 2.5 bars. Did this help to solve your problem? YesNo Home

9. YesNo Home Is the pressure on the left hand pressure gauge over 2.5 bars?

10. Completely unscrew the regulator, carry out a manual override in order to remove any impurities, then reset the pressure to 2.5 bars. If the problem persists, the doser module is defective. Contact our after- sales service. Did this help to solve your problem? YesNo Home

29. Pipe blocked - replace it. Note: This happens if you switch off the device without taking the diffuser out of the wine or if you leave it to soak in cleaning solution without disconnecting it. If effect, the wine or cleaning solution will consume the oxygen in the tubes and rise up to the dosing device, crystallise, block all the tubes and may even damage the dosing module, resulting in it needing to be replaced. It is very important to remove the diffuser from the tank and to disconnect it as soon as it is no longer in use. Did this help to solve your problem? YesNo Home
