Graco EQ300C manual Cleaning the Auto-Vent Valve

Cleaning the Auto-Vent Valve

After the pop-up has been closed while filling the pot, the auto-vent valve should release air (you should be able to hear the air venting).

The pot pressure gauge will not show pressure until the auto-vent valve has bled all of the air and sealed. If the auto-vent valve does not release air, or if water leaks from the stem during the fill process, the stem valve may be clogged or faulty.

Perform the following procedure to clean a clogged auto-vent valve.

1.Try to push and quickly release the valve with your finger. If that does not cause the valve to seal, open the dump valve to release all of the pressure in the pot.

2.Turn the selector valve to RINSE.

Repair

3.Use the rinse hose to force water backwards into the valve stem.

NOTE: If the previous steps fail to resolve the issue, replace the whole valve assembly (EQ1860).

NOTICE

The valve stem itself is internally attached to the float and it is not field-serviceable. Do not try to remove the valve stem. Damage to the equipment will occur.
