Possible Causes - Check/Repair
•
If Blocked Intake error occurs before blower runs, make
sure pressure switch connections are clean and tight.
Check pressure switch continuity/resistance. Switch
should be closed (continuity/0 ohms). Replace switch if
open (no continuity).
•
If Blocked Intake error occurs when blower is running,
check for restrictions in intake pipe, including intake air
connection, outside termination, and inlet condensate
drains (if installed).
•
Other possible causes: High wind conditions, excessive
negative air pressure in building.
•
Ensure wire connections to upper temperature probe are
clean and tight.
•
Using a thermometer, check the water temperature of the
heater.
•
Use a multi-meter and check for continuity between the
two red wires of the upper temperature probe.
•
If the two red wires are open (no continuity) and water
temperature is below 160°F, replace upper temperature
probe.
•
If the water temperature exceeds 195°F, turn off electric
power and gas supply and call Tech Support for further
instructions.
•
Confirm the water heater is full of water.
•
Confirm the powered anode wire connections are tight
and free of debris or moisture (i.e. rust, solder, metal pipe
shavings).
•
Confirm proper electrical ground to the water heater.
•
Inspect powered anode(s), clean/replace as needed.
