1. Noticed there was and obstruction in the air line that feeds the water level pressure switch. Cleaned out the air line but still had intermittent problem with flooding.
2. Evaluated the fill solenoid valve with meter and was functioning properly
2. Evaluated pressure level switch with meter and noticed that the switch was not changing state as it should when the water level is increasing. Replaced the level pressure switch, but still had problem.
4. Noticed the air line was damaged and had a hole that prevented pressure from building up. Replaced the air line and all is good!
