Fault Screen "Low Presssure/" "Cold Rinse "

A "Low Pressure" error occurs when the vessel does not have at least 3 psi.

Possible Causes:

The lid was not tight. You do not have to over tighten the lid but it needs to be snug. Usually finger tight plus 1/4 turn is adequate.

Check the lid O-Ring and replace if damaged.

The vessel did not heat, or you have a leak, therefore no pressure was generated.

To Test:

  1. Disconnect the solution supply tubes on the left side and start a run.
  2. When the screen says "Filling" pour in 2100ml of hot soapy water (dish soap works best) over the bag suspender to cover the level sensor. Agitation will begin. Close the lid.
  3. Record the temperature and pressure.
  4. Wait 5-8 minutes and record the temperature and pressure again. Both should increase over time.
  5. Place the open ends of the drain tube and vent line in separate small buckets of water. Do you notice any "bubbling" as the instrument heats?  Bubbles would indicate a drain or vent valve leak.
  6. In DELTA Service Procedure 003, the diamond markers indicate the assemblies that have attached fittings that need to be checked. Place a soap and water mixture around the fittings. Do you notice any "bubbling" around the fittings?
  7. If the vessel has pressure but the display is still reading zero, the pressure sensor and cable may need to be replaced. Contact ANKOM at 315-986-8090 or submit a technical service request at www.ankom.com/contact/technical-services
