I purchased this unit about 5 months ago and I am now needing the heat.

I turned the heat on 1 night and everything worked fine. The next night I turned it on and it would not turn on and threw the E0 then after 3 tries the E1 lockout code since it could not ignite the flames.

I had the technician come who installed it and he took the black tubes out and blew in them to make sure they were not clogged then he took the electrical connections off the switches where the black tubes are connected to and then reconnected them.
Powered it on and it still didn't work. While it was powering on a second time he wiggled the electrical connections on the switches and then it lit up and the heat started running fine.

1 week later the same thing happened and I did the same thing he did except for this time when I blew through one of the tubes that connects to what I believe to be the front drain pan water was in there and I blew bubbles. I disconnect it with my shop vac ready and about 1 cup and a hafl or so of water came out. I turn the heat on and then wiggled the electrical connections and the heat comes on again.

My questions are,
Why was there so much water and where does it come from?
Is the water supposed to be there?
Why do I keep having to wiggle these connections to get the heat to turn on?
What needs to be done to fix this?

Here are pictures since I do not know all the technical terms.

This is the unit as a whole, the both ends of the tube where the water came out are circled in yellow, the bottom end of course is where the water comes from.

This is the water coming out and me vacuuming it up once I pulled the tube

These are the switches I was talking about, we wiggled those wires connected to them and that's when the furnace finally turns on

This is the vent that goes to it outside so not sure if the water comes from here but I don't believe any water can get in that.. don't know where the water is coming from

YES it is normal.the furance pulls freash air from outdoors to the heat exchanger. Outdoor air has a higher moisture content and, when it is heated and the 93% or 95% furnace pulls all the heat out to exchange into the home the remaining air is cool so the moisture collects at the exhaust. So it flows to the collection pocket on the side from there it should have a drain to a sewer pocket or tap on a sewerline (with a loop to stop sewer gas). If the drain is uphill you can purshace a pump from a furnce supplier to remove the water. Avoid draining the water to outdoors due to freezing problems. Now from what you said without being there and the pictures are not coming up, could be a moisture problem in the room causing corrsion, you may have to replace the circuit boards or maybe a anticorrosive spray could be appyied.
