Tripped float switch in emergency drain pan. Vacuumed water out. No water was in the drain trap. This could have caused the water to spill out of the drain pan causing the water to get in emergency drain pan. Ran the system for 20 minutes and air-conditioning. Looked under unit to see if I could see any water dripping couldn’t see anything dripping around on the insulation to see if it was wet on the ductwork. I didn’t find anything that was wet not 100% sure what caused the water to go into the emergency drain pan. This Bosch air handler has a two-piece evaporator coil Horizontal drain pan. It may be an issue of the water filling up the plastic part of the drain pan and getting under the metal part where the to connect if this is The issue we may have to adjust the unit so it’s pitched toward the front and toward the drain line to try to help the water drain faster. There is also a P-trap on the unit we would replace that also with a J trap so it holds more water.
