Water Not Being Supplied to Generator

If there is no water supply to the generator, first turn the machine ON. Now, check whether the water supply is available or not. After 10 minutes of running the machine, you have to observe the supply. If no water is being supplied, then you need to check for issues with the water level control probe or water solenoid valve.

Scalants in the water level control probe give a false indication of a sufficient water level in the generator. So, remove and clean the probe assembly thoroughly to remove lime build-up or scalants. Moreover, the water condition must be cleared immediately with a good water conditioner to avoid further problems with your Vulcan steamer. Now, you have to re-install the water level probes and canister assembly.

Water may be drained through an open generator solenoid valve as quickly as it's fed to the generator. Scale particles trapped in the generator solenoid valve seat can prevent the valve from closing.

Water Accumulating in the Cooking Compartment

Water accumulation on the bottom of the steamer's cooking compartment is primarily condensed steam. Due to debris in this compartment drain screen, it will fail to drain out quickly and completely.

To resolve the problem, pull the screen straight out and clean it. Once the cleaning has been done, rearrange the screen in the correct position. Sometimes, improper leveling of the steamer also caused not drain completely.

Vulcan Steamer Achieves Pressure Slower than Normal

If the generator takes more than 18 minutes to get normal operating pressure, i.e., 3 to 4 psi, check the following steps.

A heavy buildup of scalants has possibly coated the interior of the generator. The insulating effect of the scalants hampers heat transfer in your steamer. Unscrew & remove the clean-out port plug on the generator bottom and with a small mirror check the interior.

If you notice scalants or lime buildup, you have to perform the generator cleaning. If there are significant scalants, examine both the generator drain solenoid valve and the water level control.

Check for the low incoming gas pressure. You can check the incoming line and manifold gas pressures as given by your owner's manual.

Check if the gas combination control valve has malfunctioned. If you have done pressure adjustments, but manifold pressure remains low, you will need to replace the gas combination control valve. Also, test the Vulcan Hart steamer for proper operation.

A gas orifice could be clogged or obstructed around the air shutter. Check for debris in the small gas orifice opening and clean it out. By using a round metal instrument of the same hole diameter. you can clean the orifice. Also, remove any other foreign objects that are obstructing the gas orifice or air shutter.
