Trouble Shooting "Feed water Abnormality"

• Is there water in the water tank? If there is no water, replenish it.
• Are all valves between the feed water tank and boiler open? If any valves are closed, open them.

• Is the blow valve open? If so, close the valve.

• Is the water supply pump running out of air? Open the air release valve and confirm that only water is discharged without air.

• Is the water supply strainer clogged? Clean the feed water strainer.

• Is the temperature of the water supply above 100°C? If it exceeds 100°C, steam may be returning to the feed water tank. Stop collecting condensate from the feed water tank to prevent steam from returning.

• Is there any disconnection or disconnection of the U, V, and W wiring of the feed water pump? If so, turn off the main power supply and connect the wiring.

• Are there any disconnected electrode holder terminals or broken wires? If so, repair them.

• Is the boiler full of water (water supply abnormality 10 occurs)? Blow out the boiler once and supply water again.

• Does the alarm recur after restarting the boiler? If it recurs, it should be checked by a maintenance contractor.
